Re: [PD] Pd performance at TED

[J bz]

Well with a danger of this going completely OT...

My TOTP moments are:
1.  New Order always refused to mime and when they did Blue Monday they have
the distinction of being the only group to perform on TOTP and their song
going down the chart the next week, and then the week after it went back up
again.
2. The Human League 'don't you want me baby' being the xmas no1 and just as
Phil Oakey made a super pretentious pose into the camera a sneaky audience
member hit him full in the mouth and up his nose with loads of
'silly-string'.
3. For cultural capital the dancer out of Shalimar doing the 1st examples of
body-popping on British TV.  Everyone was going nuts at school the next day.
4.  KLF.

Re: [PD] Pd performance at TED

[J bz]

I think it's a shame that in this day and age we are still promoting the
concept of high and low culture and so protective of peoples narrow
definition of what Pd is and for.

I do a fair amount of improv with Pd and it's a hell of a simpler gig
playing to 18 chin-scratching middle class people aged 40+  sat on chairs (I
include myself in that description) than 400 braying clubbers demanding you
make them dance NOW!

During Hip Hop's more militant times people like Ice T would refuse to diss
someone like MC Hammer, for example.  They took the attitude that he was one
of them, doing his best, and making headway in an industry that was the site
of the real battleground.

Ok, so nothing to worry about then:)  I was worried that there was a

Maybe I should have said but it's for interfacing with a pair of xbees

[PD] Comport under Linux - baudbits question

[J bz]

Hi all,

Just transferring a patch into Linux from W7 and I get this message in the
console which I didn't previously:
get_baud_ratebits: 115200
set_baudrate baudbits: 4098

Now I want the baudrate to be 115200, which is good but what does the
baudbits info mean - for example is it telling me that data is only coming
in at 4098? Which I don't want, or, seems a waste if the overall patch is
expecting a much faster rate.

[PD] List delete carnage - 2 questions

[J bz]

Hey all,

I'm stuck.

I have a sensor which is spitting out numbers between 1-180.

Each number triggers an event that I only want to happen once but the sensor
repeats numbers every so often.

What I require is to have my numbers in 'something', so that if that number
has already been used I want Pd to say - 'hey' and then allow me to change
that number until we find one that hasn't been used?

I have spent the last couple of hours working with my numbers in a message
box and using [list-delete].  I think it must be my usage because it's
behaving very erratically (patch attached).  If someone could tell me what
I'm doing wrong with this and then maybe I/we can get onto the main problem
- which is; what should/can I use that will tell me if a number has already
been used and spit it back at me so I can do some maths stuff to change to a
different number that hasn't been used already.

Best wishes,

Julian

[PD] Compiling Pd external using Codeblocks on Windows

[J bz]

Hi peeps,

Wondering if anyone has experience of using Codeblocks to compile an
external for Windows?

Lorenzo Sutton has very kindly forwarded me an external he has made for quad
panning using Chowning's methodology which I really like.
In the package he forwarded to me, he says that all the code is there for
building in windows using codeblocks.

I have had a quick go in Puredyne with it but I require a Windows version
for a piece next week.

I have zero experience of compiling on any platform and don't really know
where to get started.  I'm aware there are a couple of tutorials knocking
around on the pd & hurleur sites but going through them last night made my
teeth hurt.  I found a couple of Codeblocks tutorials but the .dll files I
made from them of the external don't work.

I'm sure that if I had a couple of days with nothing else on I could get to
grips with this but I don't.  What I do have is a looming deadline though!

I attach Lorenzo's external (Lorenzo if this is a problem please contact me
asap)

Btw, I have the Codeblocks version with MinGW and the GCC compiler.

Cheers,

Julian

Hey all,

I'm going to ask what is possibly a dumb question but I can't find the

Does the elevation refer to an actual speaker raised of the ground or is it
to do with horizontal position?

Also, with settings for a quad output at ground level do I want:
3 -90 0 90 0 -180 0 180 0 ?  It makes vbap complain it's not vald so I'm
doing something wrong here.

[PD] vbap not working in pd extended

[J bz]

Hi all,

I have been wanting to explore vbap in pde and I have found what may be
causing some of the trouble with it not working properly.  There is a
duplicate set of vbap files in the 'ggee' folder which have been causing all
sorts of weirdness.

Most recent pde on windoze.

I have a whole bundle of questions regarding vbap but as it now seems to be
working I am going to explore a little further first.

Re: [PD] sending audio panning with 4 speaker setup

[J bz]

Sorry, didn't reply to the list before.

I'm going to leave it as is but I have stuff to add...

Pd and its community is bloody marvellous.  A few hours ago I knew nothing
about vbap or ambisonics apart from going to some concerts/installations
where they have been used and occasional list-chatter.  I now have a basic
working knowledge, with some additional questions that I think I can locate
answers to fairly soon (well not today, I've pretty much had enough now).

Hopefully I can do some coding and get myself in a studio and hear what's
going on and code some more.  No doubt there will be more questions to come
but I at least feel I can get started.

Many thanks for holding my hand (so to speak) with this Matt and big props
to all the IEM bods, especially Georg Holzmann for his spatialisation
tutorials.

(Big aside here)
Speaking of IEM, I have an ongoing discussion/argument with a MaxMSP/IRCAM
advocate who is most disparaging about the whole FLOSS thing.  I think IEM
set an excellent example for what I like to think of as the right side to be
on, a real 'rebel alliance' if you will.  Like IRCAM are going to make their
no doubt millions of Euros worth of yearly funding back by selling a few Max
externals.

Rant over.  Calm is restored.

Cheers,

Julian




Right then Matt,

I'm going to pester you (chisel as we say in Northern England).  I have
attached my current stereo square root panner (I can make it equal power if
that's the best way to go) - am I right in thinking I need to add and
subtract 90 degrees to this signal to get the basic quad working.  If so,
how and where?

I'm sorry, I have looked at the supercollider code, and although it seems
quite straightforward, I have no idea how to implement that in Pd?

I am in the process of ripping my patch apart and using 2 instances of Pd to
help with the cpu load but I must admit to being wary of doing too much on
that front until I know what's happening with everything in the patch then
splitting the load when things are a little clearer.

Going through the Holzmann tutorials as we speak.  very good too.

Hey Matt,

Well, good to hear the zeitgeist hasn't completely deserted me then:)

Yes I'm sorry, I wasn't very clear on what it is I'm working with.  That
thing of, I've been working for ages on this and can't quite understand why
it's not bleedin' obvious to everyone else...

So, ambisonics then - eek!

Well I have to say my trigonometry is dreadful, not something I'm proud of,
just wish I had paid a little more attention in maths classes as a teenager
- too busy dreaming of pop stardom and how I would never need any of this
stuff.  Many is the time when I have heard the ghost of my maths teacher
snickering over my shoulder since I got into Pd.

I'm gonna do some experimenting and reading up before I dive into anything.
There seems to be the Holzmann tutorial, plus all the iem stuff to wade
through.  The Cubemixer looks interesting but also hefty (back to the
possible overkill) and also as msd doesn't work on my usual Puredyne OS I'm
moonlighting in W7, so super unsure about compiling stuff in W7 plus the
performer runs on a mac, so then setting it up for his machine as well.
Aaargh.  Plus the 1st performance is now only 2 weeks away!

I think the simpler the better basically.

Cheers for weighing in though Matt, hopefully speak soon.

All the best,

Julian

Re: [PD] sending audio panning with 4 speaker setup

[J bz]

I probably haven't described the space particularly well, I attach a picture
to hopefully explain a little clearer.

It's a 'swarm' of [msd] masses and links, with only the masses visible.  The
swarm is in a zero gravity space so they just float around.  The space
receives bangs/force at various points on the x-y grid triggered by an
accelerometer attached to the performers instrument.  So the swarm is in
constant motion, sorry if that wasn't clear.

At the moment I'm just using the coordinates on the x plane of each mass,
which msd handily spits out.  I have patched in the option of using the y
coordinates but I haven't used them as of yet.  Each mass controls the pan
position of a partial (of which there are 48) from the instrumentalist and
fed into [sigmund~].So the pan position of each mass/partial is slightly
different in the (currently) stereo field across 0-1.

Hope that helps,

Jb

Re: [PD] sending audio panning with 4 speaker setup

[J bz]

Hey Matt,

Thanks for pushing my understanding along...

I should have said that the pan positions are constantly shifting for 48
separate points within the x-y grid so would be, I presume, heavily cpu
intensive with some of the solutions you propose.  The patch is running off
the performers lappy and is already doing a lot within Pd.

My supervisor, the composer Aaron Cassidy, thought that as the GEM window is
projected as part of the performance with the msd swarm, that it is somewhat
'dishonest' to only have a stereo field when the visuals are obviously
moving on the y plane as well.  And annoyingly I have to agree with him.
You know when someone has said something and one feels (me in this case)
that the genie is out of the bag and there is no going back.

Cheers,

Julian

[PD] sending audio panning with 4 speaker setup

[J bz]

Hey all,

So I'm still scratching my head with controlling audio panning in an x,y
grid using 4 speakers.

What, at first, seemed like a somewhat trivial problem, upon closer
inspection ain't necessarily so.

Does anyone have examples of panning with 4 speakers?  About the only things
I have found so far are:
Building upon Hans' [pan_core~]
[pan_quad~] from 'nSLAM', which seems to be unavailable for d/l
The 'pd-tutorial' patch
3-9-3-1-spatial-quadro.pd

Anyone know about any others?

My stereo panning is built upon the square root example in Andy Farnell's
book, which I'm really happy with.  Ideally I would like to expand upon
that.

Then of course there is the whole vbap/ambisonics/cubemixer (possible
overkill) route too.  My concerns before diving into this are threefold.
1. If it's only going to work for the 2 people in the 'sweet-spot' then
what's the point?  If it makes any difference I'm using some Bose 180
degrees radiating speakers.

2. The piece is for a performer with electronics, with only the electronics
coming out of the speakers.  So I'm also wondering whether a 5.1 type setup
with the performer as the front centre speaker (as such), may be preferable?

3.  The piece requires 96 separate pan positions - how cpu intensive is that
going to be?  It currently works fine in stereo, which is why 2 lots of
stereo in an x,y fashion seems initially preferable.

I'm aware that it's pretty much impossible with this speaker setup to make
everyone in the room have a similar audio experience, and also to map my
visual masses from an msd swarm in the GEM window as audible points, but
surely it is possible to do this as an x,y grid.

I also admit that I don't understand the dsp theory necessary to make the
x,y, grid idea happen so if anyone has some pointers regarding that I would
be delighted.

Cheers,

Jb

[PD] Quad Sound question

[J bz]

Hi all,

I have a 2d 'swarm' of [msd] in a GEM window.

Each mass has 2 audio partials mapped to it's location, 1 on the x axis and
1 y.

What's a good way of mapping the output within pd so that the visual is
mirrored within a quad speaker setup.

So 1 stereo pair left to right and 1 stereo pair bottom to top?

I want to keep it in Pd so it's not soundcard specific.

Julian

Re: [PD] Sigmund~ and tracks.

[J bz]

Hey William,

Appreciate the involvement...

Unfortunately I'm on W7 atm.  My main patch uses the MSD lib and after what
I thought was a trivial problem with using it in Puredyne (my regular
distro), last Nov, MSD is still not working for me.  Fortunately I bought a
2nd hand lappy with W7 on it early Dec, so have been working in that since.
The instrumentalist is a Mac guy but that doesn't help me prepare the piece.

So yeah, a long way round of asking do you have a windows version?

Funnily enough I was nosy'ing around your site a couple of months ago and
d/l'd the timbre ID lib for further research.  Looks well good:)

Best wishes,

Julian

Re: [PD] Sigmund~ and tracks.

[J bz]

Thanks guys, that's really helpful - got things a bit straighter.

So can I say for clarification (and I noticed it came up on an earlier
thread when (of the top of my head) someone was asking why the attack
settings didn't work for tracks and they had to use [env~] -
vibrato
stabletime
minpower
growth

Have no effect when in 'tracks' mode./?

Not really sure what to do with the viola d'amore source sounds if they are
just not going to be stable.  Having the huge hop & npts settings seems
kinda counter-productive and also introduces a significant delay.  I guess
if I want a smoother sound I could always sample and loop a small portion of
the viola sound as he plays.  My thinking atm is to go with the sound from
sigmund 'cos that IS the sound.

BTW,  I started out with fiddle~ and sigmund is much more responsive and
more importantly better sounding.

Anyway back to the flags and my attacks and decays I guess.

Very best wishes,

Julian

Hey William,

Ho hum...,

Cheers for having a look though.

I'm not completely clear about the continuation flags?  I can see from the
help file that they're there but what do they mean?

Perhaps this should be a new thread but why does sigmund have a frequency
range of 100,000hz, and what would be a decent useable range from practical
experience?

Re: [PD] Sigmund~ and tracks.

[J bz]

Hey William,

Many thanks for offering to have a look at this for me.  I'm currently
trying to extricate the offending section out of what has now ballooned up
into a very involved patch (certainly for me anyway).  In the process of
doing this I have realised that I am mistakenly constantly sending attacks
and decays to the[osc~]'s.  It would probably be best for me to just send it
'as is' rather than trying to sort it out.  I'm somewhat in over my head
with this as it is (maybe not always a bad place to be) and could really do
with some advice/help/coding-elegance as my brain is starting to melt.

Mathieu,

If you mean the tuning of the viola, yes it's the standard D Maj tuning, low
to high A D A D F# A D.

Very best wishes,

Julian

P.S. Back soon

[PD] Sigmund~ and tracks.

[J bz]

Hi all,

I'm doing a piece with a viola d'amore (7 string viol) where [sigmund~] is
analysing the live input and feeding 48 tracks/partials to a bank of 48
[osc~] for resynthesis and a bit of jiggery-pokery, mainly reversing the
amplitudes so the quietest partials are the loudest and vice versa.

The viola is playing long(ish) single notes between 1-3 seconds and the
problem I am having is that when sigmund processes the partials they come
out rhythmicised/pulses which seems to be a combination of the 'hop' and
'npts' settings.  As the values for hop and npts get higher the pulses get
longer up until my current huge setting:
[sigmund~ -npts 65536 -hop 65536 -npeak 48 tracks]
when the partial frequencies balance out into steady lines.
I have also tried -hop 131072 which works too but trying that with the -npts
completely locks pd.

The problem I have now is that there is a significant delay between the
beginning of the processing in comparison to the viola and worse still is
the overlap after the viola has stopped playing.  Also the viola notes are
indeterminate so I can't just set a cutoff to sync the two together.  I
could use the input of the viola to gate the tail of the processing but I am
currently using a combination of [env~] and [lop~] so that as the performer
plays his amplitude controls the processing in reverse, so when he's loud
the processing is quiet etc.  I suppose I can add another layer on top of
the end

I am aware that the gap between the two sounding events is caused by the
huge window sizes I am using and that there may well be no way around this
to get the kind of sound from the processing I'm looking for, i.e. without
the pulses, but I am wondering if anyone has any tips and tricks I can apply
to try and bring the two sounds, viola and processing, closer together.  Or
ideally some way of achieving the smoother processing with lower npts and
hop settings. This is for a live performance btw.

All good wishes,

Julian

Re: [PD] Combining two audio signals

[J bz]

Hi Lorenzo,

Yes, I should get into using [lop~] more for this kind of thing, instead of
reverting to [line/~] which doesn't work as well in this instant.

Many thanks,

Julian

[PD] Combining two audio signals

[J bz]

Hey all,

I have two audio signals, 1 instrument input and then some processing of the
instrument.

What I want is for the processing to work like [swap] where when the
instrument is loud the processing is quiet and vice versa.

My question is how can I do this smoothly without there being big jumps at
the beginning and end of the processed sound?

Cheers,

Julian

Re: [PD] msd puredyne errors

[J bz]

Hey Nicolas,

Yes, very strange behaviour indeed.

As [msd] comes 'pre-installed' there doesn't appear to be a msd.h file.

I did look at trying to build msd as a possible work-around, though I must
admit it seems a little beyond my experience.  I got stuck when attempting
to install flex when I realised that there is no source files (as far as I
am aware) for Pure Data either.

This is not to complain about puredyne - it's a marvellous distro.

Anyways, here's the latest output:

[PD] msd puredyne errors

[J bz]

Hi all,

I'm working on quite an involved patch using the msd library and for some
reason it just doesn't work happily on Puredyne.

So for example, the '02_msd2Dadd' example when loaded gives a stream of
error: msd2D - link : Index not found
messages out of the console.
This is the same error message I receive when loading my msd.txt file
containing all my data.

Other examples from msd2D:
1.  Works
2.  See above
3.  Crashes pd
4.  As 2
5.  As 2
6.  Works

I have tried the Puredyne mailing list but I ain't getting anything so
thought I would try for some help from here.

If anyone can help me track this down I will be immensely grateful.

Cheers

Julian

Re: [PD] Musical notation object on Pd

Hey Ed,

Many thanks for getting back to me about this.

The score needs to be generative but that wont stop me having a good mooch
around 'Bleep':)

Many thanks for the font and the cpu freq gov too, looks like a vital piece
of software.

Best of luck with your piece, I know the stress involved with looming
deadlines, looks like it will be good though. UoEA is a bit far for me but
if all goes well you should get in touch and we should see if we can get you
a gig up in Huddersfield where I'm currently based.  Certainly sounds like
the kinda thing we're into up here.

[PD] msd structures and force

[J bz]

Hi all,

I have created a 2d grid in msd and I have a question regarding the use of
force...

I'm going to have to mix my metaphors here I think:

Is it possible to send force so it acts almost like in layers so that, say,
I have my grid;
 ._._._.
|._._._.|
|._._._.|
|._._._.|

which is fixed.

I would then like to add a ball (for want of a better descriptor) which can
travel around the grid by being 'blown' by an overall x,y type force (which
I already know msd has/can do).  On top of this I would like the separate
masses and links to be capable of speeding up and slowing the 'ball' as it
travels around the space.

Pinball on train-tracks sort of thing (how's that for a simile:)

Is this even possible and if so how do I go about it?

Also, what's the best way of doing the grid?  At the moment I have one
version where all the masses are fixed and another where just the corners
are fixed.

Many thanks in advance,

Julian

[PD] msd-editor persistence question

[J bz]

Hi All,

Finally got msd-editor working (I think) and I have a few
questions...(hopefully not too dumb)

Most immediate is how do I save the structure I have created as a pd patch?
I'm aware I can save the DS as a txt file but does that mean that I have to
go through the editor everytime I want to use the structure?

Cheers,

[PD] msd puredyne

[J bz]

Hi all,

Before I add a bug report can I ask if anyone using puredyne can confirm
whether the msd library and/or the msd-editor is working for them?

Both are packaged with puredyne but I'm having no joy with them at all(
apart from the [msd] object itself, so no 2d, 3d etc.

Very best wishes,

Re: [PD] Attaching a Sensor to Acoustic Instruments Question

[J bz]

Hey all,

I love this list:)

I had thought about wiimotes but I think they are too cumbersome, visible
and heavy.  I would like the instrumentalist to not have to be aware that
they are connected to anything.  The point of the tracking is to use the
performers involuntary movement as input data for the pd patch, so I would
like for them to be as un-selfconscious as possible.

I have heard that there are problems with bluetooth in concert situations,
although the feedback I have just received from you guys seems inconclusive?

Although this is in a university setting for the 1st performance, I'm also
really keen that this can be portable and as inexpensive as I can make it,
thus hopefully allowing the piece to have a life outside of academia.  This
would prohibit going down any super-complex routes.

I think I would be more comfortable not having to rely on the sensor being
in the line of sight too, sounds scary.

Brilliant feedback so far though, thanks a lot, I have plenty to get on
with.  I will, no doubt, be reporting back soon...

Cheers,

Jb

[PD] Attaching a Sensor to Acoustic Instruments Question

[J bz]

Hey all,

I'm working on composing a piece within pd for viola in which I would like
to attach some kind of sensor to the head of the instrument.  The sensor
must be capable of tracking the performers movements on the x,y,z axis', be
undetectable for the performer, and be wireless.  I'm not sure whether
something arduino or some sort of bluetooth device would be preferable?

Would be very grateful if any listers have any experience in these matters
and could recommend some devices, pointers of things to watch out for
(bluetooth in concert venues for example), general sturdiness of various
items, etc.

Many thanks, and best wishes,

Re: [PD] Arduino Humidity/Temp Sensor Problem

[J bz]

Hey ub,

Thanks for the triple response:)

I think we got the wrong end of the stick somewhat.

We thought that the pduino firmata was akin to an O.S. and the sketches we
uploaded to the arduino was like software.  Guess this is not the case then.
Will put the pdiono firmata back on again and have another go.

We went googling because the original pduino firmata wasn't working and
found that piece of code.

Will try again and report back.

Cheers,

Julian

[PD] microtonal pitch glide using Risset's bell

[J bz]

Dear List,

I have a basic rip of the Risset Bell from the tutorial patches and I can't
seem to figure out how to make the overall pitch glide from one microtone to
another from midi number 72 to 72.4 over 15ms, for example?

A month old baby and a looming deadline has turned my brain into mush...

Patch is attached (it's for an upcoming performance of John Cage's
'Ryoanji').

All good wishes,

Julian

Re: [PD] Phase and impulse response measurement

[J bz]

For impulse response there is this:

Not fully explored this yet but it has been on my todo-list for too long...

Re: [PD] Fwd: GEM Neupert Tutorial '10-av-more control'. How do I play more than 1 video?

[J bz]

Hi Fernando,

Apologies for the late response.

I (re)encoded the films in Avidemux on my Puredyne machine using the mjpeg
codec.  There is a Windows version of Avidemux too.

I switched to borrowed Windows and Mac machines for testing as my Puredyne
lappy wont drive the patch.  Too processing intensive.  I had more problems
on the Windows 7 machine but that may well have something to do with running
32b pd on a 64b machine, not sure, and didn't have enough time to test
thoroughly.

There seems to be so many possible variables with OS's, graphics cards, etc.
etc. that each use of video within pd has its own particular set of
problems.  As my films are quite static I reduced the frame rate and
quality, which seemed to help.  As someone just starting to work this way it
does seem to have some tricky issues.  I'm fairly determined to keep my work
in pd so I expect to pick up more tips and tricks as the work progresses.

Best of luck with your patch and I hope the recoding may do the trick.

All good wishes,

Jb

Hi Jack,

Aaah, thank you indeed.

I checked the original on a mac today, and it sort of worked, no crashing.

Will report back after more testing.

Not the first time you have waded in and lent a hand, much appreciated.

Re: [PD] Fwd: GEM Neupert Tutorial '10-av-more control'. How do I play more than 1 video?

[J bz]

Hi Benjamin,

Thanks for that, I will check it out.

Jack,

The machine I was testing with today was very souped-up and the [dsp] object
never got over 25%.

I don't know if this would make a difference but the avi's are slightly
longer than the audio, if the audio is driving the sync is it possible that
that could cause the crashes?  Also audio is 32bit floating point, if that
could make a difference?

Still somewhat unsure about the best way of using the abstraction, if as I
thought, to use 3 files I need 3 gemheads, how can I use 1 abstraction that
contains a single gemhead?  That was the impulse to use three different
files.  Then if I'm using 3 different files, why do I need to use $0, apart
from good coding practice??

Guess I'm thinking aloud here.

With the first version that I made, all the files load fine and play, though
there is now no sync now I stopped using [readanysf~].  S'pose one of the
joys of pd is that there are umpteen ways of skinning any particular feline,
though I really don't have the time to be starting from scratch again with
this.

I'm going to make the audio 16b and trim the avi's so they are the same
length as the audio.

Otherwise I'm really unsure what's going on This whole codec thing is a
bloody nightmare.

Will try again tomorrow.

Cheers,

Jb

Re: [PD] Fwd: GEM Neupert Tutorial '10-av-more control'. How do I play more than 1 video?

[J bz]

Avi's are 10fps mjpeg recoded in avidemux.

Audio 44.1 wav in audacity
All files play fine on the windows computer on their own.  I do get audio
and one video, which works great.

They also play fine in my earlier patch when I was first experimenting with
GEM and video.  I went the Neupert way because I wanted more control.

Other problem is that my ancient laptop wont come anywhere near running the
patch, which is why I'm at a friends house.

Aargh, this is bad, supposed to hand this in tomorrow.

I have to go for a few hours but will be back later.  Back at my friends in
the morning but will be online again in a few hours.

Attached is my original patch too.

What I want is the ability to scrub audio and video but something that
works.  Obviously.
I was using [redanysf~] but the work needs to be seen on windows and mac and
readanysf doesn't seem to work on windoze.

I guess the most frustrating thing is that I have spent all afternoon
wrestling with something that seems to be working on other computers. I
added the [set( message as I have been trying anything I could think of.

Thanks again,

Jb

Hey Jack,

I presume it's working for you with you using the 1 abstraction and $0
arguments rather than separate abstractions?

[PD] Fwd: GEM Neupert Tutorial '10-av-more control'. How do I play more than 1 video?

Hey Jack,
Thanks a lot for that.

It's still crashing when I open the second avi.:(

I used different abstractions (correctly or not) because I'm using three
[gemhead] 1-3 to play the videos.  I thought that is the way no?  So each
abstractions contains a different gemhead.

Even though I have given each abstraction a different name, they all have
the same canvas i.d.?

Very confusing...

Again, thanks a lot though,

Jb

Re: [PD] GEM - The Relationship Between [translate] and [rectangle]?

[J bz]

Hi Max,

Cheers for the quick response.

tbh, pix_film is the reason I know the pixel dimensions already:)

Would you mind explaining in a little more detail - which objects and how?

I am unclear on the relationship, say, between [rectangle 3 2] and 320x240
pixels, and again how that corresponds to [translate] and the numbers I am
putting in the inlets 2 and 3 of translate.  For example when I increase the
2nd inlet of translate (magnification? sorry I'm not in front of pd atm) my
2nd avi movie moves in a north easterly direction from within the gemwin and
I don't understand why?

Kind regards,

Jb

[PD] GEM - The Relationship Between [translate] and [rectangle]?

[J bz]

Hey again,

So,

I have my 3 avi's with 3 seperate [gemheads] which I can now move around the
[gemwin].  Cool.

Could someone enlighten me towards the relationships between [translate] and
[rectangle] please?

I would like to keep the original aspect ratios for the 3 avi's.  Avi 1 is
an odd shape  - w432 h768 - (it's approximately half of my laptop desktop
recorded with RecordMyDesktop) and avi 2&3 are recorded off bog-standard
camera's, so are 320x240. The larger file is on the left of my gemwindow
with the 2 other avi's to the right, one above the other.  I have added the
widths of film 1 and film 2 with little borders which gives [dimen 762
768(.  I can move the files around and get an approximate fit moving between
each [translate] and [rectangle] but I get the feeling there is a more
rigorous approach.

Apologies in advance if I have missed something in the helpfiles or various
tutorials but I can't seem to find the info I'm looking for.

Best wishes,

Julian

[PD] GEM with multiple movies

[J bz]

Hi all,

GEM newb alert!!

I have 3 movies/films/avi's that I wish to play at the same time in GEM and
I'm not sure of the best approach?

I have finally after much messing got the contents of RecordMyDesktop
working as an AVI in GEM, and now I wish to add 2 further avi's to run
concurrently.  I'm aware I need to do some jiggery-pokery to sync these up
to an audio track but my current question is:

Can I arrange the 3 visual files within 1 GEM window [gemwin], and what is
the best approach to this, or do I need to set up 3 gemwin's with a
[gemhead] each/is this even possible?

Been messing/nose'ing around all day with this but haven't come across an
answer to my question.

All good wishes,

Julian

Hey IOhannes,

Yeah I thought about moses but doesn't moses always start at 0?
Ideally I would like something with a range between 2 settable limits.

[PD] numerical constraints

[J bz]

Dear all a y'all,

I have a list of 25 numbers between 800-19000 that I'm calling randomly'ish.

I want to add some constraints to those numbers:
so for example, I have the number 6569 and by the use of either simple x2
multiplication or dividing I want to shoehorn it into the ranges of
11000-18000 but also 400-800 at the same time.

THe ranges are set but the numbers aren't.  So say sometimes the range
2400-4700 may get a number that is less than the range like 912 and
sometimes it will get a number over the range like 13264, so I need a way of
Pd recognising whether the number requires multiplication or dividing.

How can I do this?

Bests,

Re: [PD] making scales from frequency values

[J bz]

Hey Matt,

Not windy at all:)

My current inclination would be to not use equal temperament.  Though the 19
note scale is appealing creatively.

I guess, if anything, I'm currently thinking that a limited number of ratios
may be the best solution.  Some of the things I have said on a post I sent
about an hour ago that still hasn't popped up yet, describe some of my
current thought. I've also forwarded my piece as it currently stands with my
last post entitled 'Bit Chime (rough draft)'.  Hope it appears soon.

Re: [PD] making scales from frequency values

[J bz]

Hey all,

First off can I say a very big thank you for everyone who's contributed so
far.  Some really excellent input which has helped to clarify my thinking no
end.

Let's clear a few things up first:

It is a ratio problem I believe. The initial problem stems from trying to
shoehorn the original ratios/partials from the analysis of my 5 chimes, into
equal temperament.  There are a couple of reasons for this;  I've been
playing around on the piano after assigning each partial to its nearest
midi/equal temperament note, and was liking the results that ensued whilst
listening to them on the piano. Obviously the tones generated on the piano
are much richer than individual sines. The original wind chime has been sat
over my desk for the last 18 months,  so I'm also very attuned to the
original sounds. I would also like to have the various partials to be as
modular as possible with the idea that I can 'mix'n'match' the various
frequencies of the chimes to create new sonorities.

When I listen to the results of using equal temperament within my patch my
ears don't like the results in comparison to the original frequencies, which
has led to the current predicament.  As I previously stated my maths is
rubbish (I'm more of a musician/composer background than computing), so when
faced with the logarithmic aspect of frequency and pitch, my mind went into
meltdown.  But it is much clearer now (I believe).

Perhaps I should state what it is that I wish to do:

I started with the midinote idea as a hopefully simple way to be able to
introduce some controlled randomness into the frequencies of the chimes
whilst preserving the ratios.  What I want to do is be able to assign any
ratio from my analysis into any of the 5 chimes - so say have a chime
consisting of the 1st partial from chime1, 2nd partial from chime2 etc
and then any possible combination therein.

So my thinking has been to have some sort of central control which would
then send the necessary value to the 5 'osc~' that make up each chime.  I'm
trying to conceptualise/clarify the simplest method.

I think what will make things clearer is if I forward the patch as it
currently stands

Gonna do that now

Big props peeps,

Jbz

Re: [PD] making scales from frequency values

Dear Mike and Andrew,

Thank you for your speedy responses, though I think I am not explaining
myself very well.  I don't want to use mtof or ftom as these objects even
out my ratios.  What I'm looking to do is create a scale (say 12 notes for
example) out of these ratio's with the possibility of filling in the
consonant gaps whilst preserving the original frequencies and ratio's.  The
1st number in each group is the strongest partial so: 912Hz, 1081Hz, 1211Hz
etc.  If I'm saying that these frequencies are 'good' to my ear, is there a
way of creating equally 'good' sounding notes to fill in the gaps in, say
for example, a 12 note scale based on these notes scaling from the lowest to
the highest without doing the whole thing 'by ear'?

Cheers for weighing in,

Jbz

[PD] making scales from frequency values

[J bz]

Dear all,

I have five chimes.  I've worked out the frequencies (using Audacity) of the
5 strongest partials of each chime.  I now want to be able to work out how
to change the octaves of the various partials?  My original intention was to
find the nearest midinote and just use those but after listening to the
results I would much prefer to keep the original ratio's whilst being able
to alter the 'inversions'.

Here's the list that I have already:
BT1
912Hz
  2434Hz
  4575Hz
  7175Hz
11584Hz

BT2
  1081Hz
  2861Hz
  5339Hz
  8325Hz
15209Hz

BT3
  1211Hz
  3196Hz
  5935Hz
  9199Hz
15206Hz

BT4
  1347Hz
  3553Hz
  6569Hz
10128Hz
18139Hz

BT5
  1812Hz
  4699Hz
  8525Hz
13264Hz
15469Hz

Is there one piece of mathematrical wizardy that can sort this in Pd?

Cheers,

Jbz
