[PD] Help - filters & band limited oscillators!
Hello everyone, I tried google and it was no help, and the server for the list archive seems to be down temporarily. Anyway, I'm giving a free (as in free beer) workshop in Chicago in about 16 hours, on the basics of digital synthesis. I have decided to use Pure Data to give my presentation, and use mostly non-commercial software. However, I'm still missing the following for demonstrating "proper" subtractive synthesis: 1. Good, out of the box "analog-sounding" filters. I'm using [moog~] right now, but I'm not all that satisfied with the sound compared to the filters in my favorite VST's ... 2. Band-limited square and sawtooth waveforms. For teaching purposes PD is great, and ideal for my demonstrations. But as it is, I'm having to use VST's within PD in order to demonstrate a "nice sounding" synth. It would be nice to show that PD can do it without using stuff built in Steinberg's format. That would also let the Mac people replicate my work, if they are interested. Note, nobody in the workshop has ever tried Linux, except me, so Linux plugins are not helpful in this case. I will post my patches after I give the workshop, though they are nothing fancy ... just basic: sequencer - oscillator - vca - filter. Good for demoing though, I'm starting with additive first, then subtractive. ~David ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list

Re: [PD] Help - filters & band limited oscillators!
I found those, but are they really band-limited? I'm fairly sure I hear ugly digital artifacts in the saw. The square appears to be broken, unless I made a mistake cutting and pasting those 1500 lines of code into my text editor (kinda hard to tell). It's 5 30 am here and I've not slept yet :-( I can't believe there's STILL no readily available external/abstraction for such a common synthesis task, I just want a "nice sounding" example that will compare with the VST's which I will be hosting from within PD; right now "ASynth" sounds about 100x better than anything made in PD itself ... Oh and I don't see any "J" example PD patches, my PD patches don't go that high. ~David On 3/14/07, Roman Haefeli <[EMAIL PROTECTED]> wrote: > hello david > > i found examples for a bandlimited saw and bandlimited square by g. > geiger in the archives. might this is what you are looking for. > > http://lists.puredata.info/pipermail/pd-list/2006-05/038681.html > > cheers > roman > > On Wed, 2007-03-14 at 03:05 -0600, David Powers wrote: > > Hello everyone, > > > > I tried google and it was no help, and the server for the list archive > > seems to be down temporarily. > > > > Anyway, I'm giving a free (as in free beer) workshop in Chicago in > > about 16 hours, on the basics of digital synthesis.

Attached is a bandlimited square, which was bandlimited using the upsample, then filter approach described in The Book. Another approach would be additive synthesis, as illustrated here: http://lists.puredata.info/pipermail/pd-list/2006-05/038681.html (There are two patches in that mail!)

Re: [PD] adding external-direcetories to paths
Thanks again Steffen, I think everything is a bit easier to grasp now, all though I'm having trouble making the ':'-trick work as expected. I've tried seperating paths with ';' instead, but when I load PD the next time each path has been assigned it's on path-line in the preferences. Maybe assigning a path in the object itself, as you propose, is my solution too. Yes I was thinking about Labsalonen at LAB, at least it could become a place where people who are into PD can meet once a month, since whats going on at Labsalonen is what people themseles wants to do. But if there's enough interest for a dedicated PD-patching-group in Copenhagen I'm sure something can be arranged. Unfortunately I havn't got the time to arrange or manage such a group, but I could be the contact who can open the doors at LAB and make the room available from time to time. Cheers!

[PD] pdp 0.12.5-darcs on Linux
Hi, I am trying to get pdp working on my Linux box: Ubuntu 6.10 (2.6.17-10-generic, X11 7.1.). I am using the fglrx video driver with direct rendering enabled. So... How do I get pdp to render to the screen? [pdp_xv] loads correctly but sending it a |create( message gives: pdp_xv: cant open display :0 [pdp_sdl] and [pdp_glx] both cannot be instantiated: '...couldn't create', despite the fact that I compiled with --enable-sdl and --enable-glx. Anyone know what I need to do to get this working? Thanks, Jamie ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management -> http://lists.puredata.info/listinfo/pd-list
Re: [PD] Help - filters & band limited oscillators!
hello again i improved guenter's bandlimited square a bit. i noticed that it is hardcoded to 48kHz and accidently i was running pd at 48kHz, that's why it sounded quite good here. however, how far i can see it, the part, that selects the appropriate table, is not working as it should. i couldn't completely follow, how it works, but it seems to switch only correct from tab1 to tab2. for other tabs it switches at too high frequencies, which might introduce a bit aliasing. in my version the tables are generated on loadbang, which makes the file much smaller and easier to adapt for other waveforms. the tabselector is now dependent on the sampling rate, so it should sound well at different rates now. in order to provide the full spectrum even in low frequencies, i added a raw square generator. below a certain frequency, the oscillator switches to the raw square version, so that it should sound good at arbitrary low frequencies. the number of tables generated on loadbang can be changed. a bigger value lowers the frequency, at which the oscillator switches to the raw version and vice versa. i hope you'll have fun with it. roman On Wed, 2007-03-14 at 04:46 -0600, David Powers wrote: > I found those, but are they really band-limited?

[PD] GOP and menu displacements [was: oldschool rave synths]
Hallo, Andy and me had a little off-list discussion, but this below may be interesting to others as well. padawan12 hat gesagt: // padawan12 wrote: > A problem often comes when you activate GOP on a patch - to be honest > I've never understood any reason to why it selects one particular > place as the GOP center, is it just random? Anyway, this often requires > moving objects up and left beyond the frame. Actually as default Pd always puts the red rectangle to the same position at coordinates x=100, y=100. The origin of this coordiante system (x=0, y=0) is in the upper left corner of a patch normally, the positive x-direction is to the right, the pos. y-direction is down(!) from there. However if you move objects into the area with "negative" coordinates left or above the patch's borders, Pd will still show them, but it will move the origin (0, 0) to somewhere in the middle of the patch. The red GOP rectange still is at (100, 100), but now it may seem to be at a different position, because the origin (0, 0) doesn't match the window-borders anymore. I suppose that Pd will try to create the Properties menu at a position indicated by the object's coordinates, but it will reference a different origin, that's why the menu seems is displaced. Well, all this is very confusing, that's not moving stuff to the negative area is quite important.

[PD] forcing focus to and minimizing the GEM window
ver you want with it (e.g. use iemmatrix to calculate what you need). another solution with Gem might be to use [pix_resize] with a width of 1 and then [pix_dump] the image "column". other libs: i am sure there are some simple resizing mechanisms in GridFlow. if you need to do more complicated stuff on the data, GridFlow might be a good choice anyhow, since you could stay in grid-space rather long and only do the conversion into pd-space at the very end. pdp/pidip: i don't know, but i am sure there are solutions here too. so it really depends on what else you want to acchieve. if it has to run on w32, then the solutions are limited.

Anyway, I'm giving a free (as in free beer) workshop in Chicago in about 16 hours, on the basics of digital synthesis. I have decided to use Pure Data to give my presentation, and use mostly non-commercial software. However, I'm still missing the following for demonstrating "proper" subtractive synthesis: 1. Good, out of the box "analog-sounding" filters. I'm using [moog~] right now, but I'm not all that satisfied with the sound compared to the filters in my favorite VST's ... 2. Band-limited square and sawtooth waveforms. For teaching purposes PD is great, and ideal for my demonstrations. But as it is, I'm having to use VST's within PD in order to demonstrate a "nice sounding" synth. It would be nice to show that PD can do it without using stuff built in Steinberg's format. That would also let the Mac people replicate my work, if they are interested. Note, nobody in the workshop has ever tried Linux, except me, so Linux plugins are not helpful in this case. I will post my patches after I give the workshop, though they are nothing fancy ... just basic: sequencer - oscillator - vca - filter.

Re: [PD] external viewers for additional file types ?
Yes, adding some minimal sanity checking of the files to be opened
will make the browser more solid, and for all we know, checking
the "magic" prefixes of files is a snap. BTW, for kicks I tried to open
a .wav file (there are a couple in the examles somewhere) knowning
the problem guess what happened :-)... fixing this can be a
good thing. I volunteer, but please read on.
About the general position about expanding/not-expanding viewing
capabilities I guess it is a matter of perception by the user of
whether an implementation is "complete".
As an example of what I mean about "complete", when an entity
that is named "browser" presents a list of items, it seems
reasonable to expect that it will be able to "handle" the listed
items in a manner consistent with their type. I dare to submit
that this is kind of software engineering common wisdom. If
it can not handle something, don't list it.
But eliminating things from the list because it can not handle
them, renders the browser incomplete: it is not listing
everything it sees, even though it is still displaying subdirs of
the help dir. To me this does not seem right.
Furthermore, I tried to find any justification for having support
(i.e. launch a viewer for) e.g. .html files and not for pdf files.
HTML is a standard markup format for which there are plenty
of free and legal viewers.
PDF is a standard markup format for which there are plenty
of free and legal viewers.
Folks publish documents for PD in HTML format. e.g. many.
Folks publish documents for PD in PDF format, e.g. IOhannes.
Now (STARTING OF THE ROLLING DRUMS prr)
THE DIFFERENCES ARE!!: .. fill the blanks with what you
believe the differences are I am sure that you will find a hard
time to exclude one or the other, and HTML support is already
in.
An the obvioius question is *why* to exclude, rather than include,
approaching completeness, rather than perpetuating incompleteness.
The documents and other files (e.g. the Gem demo movie) are
utterly useful as help tools: why would we force new users to
open 10 applications to navigate separately to each of these
docs or files when it is perfectly possible, and easy, to support
a decent number of them. And in fact, it is even easier to launch
a standard script that the user can modify to add whatever crap
she wants.
There is very little to code here, and doing it "open ended"
make it very easy to port to various platforms. Very flexible.
Yet, as you say, and I agree, there is no real "necessity" to
add this. It is just cheap convenience and completeness.
PD can live without it, as it did so far.
Look forward to hear your thoughts.

Re: [PD] Help - filters & band limited oscillators!
Hi Roman, I get the following error from your patch, for many of the tables: error: 1002-square33: number of points (512) not a power of 2 plus three Along with this error, it seems to stop playing somewhere above 360 Hz... Thanks for your help, I'm sorry to sound grumpy, it's just that in searching the archives mostly all I found was my old query for a year ago. Plus everyone says to use [blosc~] but I posted in my first post, that [blosc~] is broken, and I believe that it's known, ie here is says: http://blog.soundsorange.net/index.php/archives/2006/09/28/exploring-pd-extended/ "exploring pd extended 27/9/2006 CPU load rating blosc~ - intriguing band limited oscillators, but patch is self referential and not working" Again, a reminder that this isn't really for me, but rather, it's the list members chance to sell other people on PD being useful, or not, to the outside world. [vst~] is working great so I can demonstrate subtractive synthesis with VST's within pure data, but that's suggesting to people that PD isn't really good for traditional synthesis... So if you think PD is good for synthesis, let me know about it!!! ***Note: I personally don't use PD with Gem for VJing, and to make weird generative MIDI sequences, mostly...

Re: [PD] Help - filters & band limited oscillators!
Did anyone try sqosc~ yet? I'm interested to get feedback on that one. http://pure-data.cvs.sourceforge.net/pure-data/externals/mrpeach/sqosc~/ Martin David Powers wrote: > Hi Roman, I get the following error from your patch, for many of the tables: > error: 1002-square33: number of points (512) not a power of 2 plus three > > Along with this error, it seems to stop playing somewhere above 360 Hz... > > Thanks for your help, I'm sorry to sound grumpy, it's just that in > searching the archives mostly all I found was my old query for a year > ago.

Re: [PD] Help - filters & band limited oscillators!

I've got visual C++, and cygwin... ~D On 3/14/07, Martin Peach <[EMAIL PROTECTED]> wrote: > Did anyone try sqosc~ yet?
