Since you want it to be monophonic, why don't you just force a note-off for
the previous note, right before the note-on of the new note ?
If you want rests inbetween the notes you could also use [pipe]---[pack f
0], and [flush( the [pipe] when a new note arrives, so that if the previous
note had not finished yet, the scheduled note-off for it is sent early,
before the new note-on...
does that make sense ?
(attached is an example)

I would try and catch this before your [makenote] is triggered
(assuming you're using [makenote]) Maybe something like this:

[random 127]
|
[t f f]   [r oldnote]
| |   |
| [!= ]
|  |
[spigot]
|
[t f f]

| [s oldnote]

[PD] emulating the behaviour of a midi keyboard: trouble with repeated notes

[Athos Bacchiocchi]

 hi,

i'm working on a little project in which some notes with random pitches and 
duration appear at random time intervals. Each note is packed in a "midi" 
format (pitch and velocity), with a note-off event (pitch and zero velocity) 
sent after the note duration interval.

 it can happen that a new note is generated before the previous one has been 
stopped.That's not a trouble, since i  can handle it with [poly], eventually 
set to 1 voice and with voice stealing to force a "monophonic" melody. 

The problem appears if the new note coming has the same pitch than the previous 
one. This is impossible for a "real" midi keyboard, in fact a key can be played 
again only after it has been released.
This leads to an undesired behaviour of [poly]: if there are more than 1 voice, 
i have the sum of different voices playing the same note, with an undesiderd 
increase of the volume. Even worse, when the voice is only one, the note-off 
message of the previous note stops the new note before its assigned time 
duration!

I tried to set up a strategy to avoid this, but with no results.  Any idea?

thanks,
athos

Re: [PD] PD/GEM examples

[Joseph Gray]

In case you're interested here's the workshop outline (which is also  
just a bunch of links).  It has a few collected examples at the top  
there if you ever need to copy/paste some:


http://grauwald.com/workshops/pd/

The history section is a bit vague in places.

Earliest mention I can find of Mark Dank's GEM is from 1998...  is  
this really true?  Pioneering.

Is there a patch for the pd-extended 0.41.4 pd source for the table  
bug?  That's all I really need right now as I can build the  
externals ok.



Try Pd-extended 0.42.5.  There are nightly builds, or get the source  
via rsync or svn.

[PD] max externals to pd port

[komika]

hello list
i have set up a download site at http://www.komika.org for externals 
which read and play back timecoded vinyl (at the moment only traktor 
scratch vinyl is supported).
These externals are written for Max/MSP. I am wondering if anybody is 
interested to port those externals to PD.

I would encourage it!

A Pd-vanilla approach to table manipulations is sadly lacking, and list-abs
is a beautiful API to adhere to.

I'm sure that many rj-dj programmers wouldn't mind something like this...

Re: [PD] arduino melody example in PD?

[altern]

That sketch is playing a tune making square waves of different 
frequencies. That's not really the same as PWM, which varies the length 
of the pulse, but the frequency stays constant. There are a few ways to 
generate a square wave of a given freq. in Pd, if that is your goal. If 
you want to do it by modeling the Arduino's use of a timer to turn a 
signal on and off, that might be an interesting exercise. One easier 
way, though, would be to amplify and clip a sine wave.

arrays, like in the Arduino sketch, where the freq is sent to the  
[osc~] and the duration is sent to a [delay] that sends a bang to a  
counter that increments to the next array elements. Then it will play  
"Twinkle, twinkle," and what could be better than that!

hi

i have been trying to port this example to PD

http://arduino.cc/en/Tutorial/Melody

it just uses a piezo to buzz a song. i dont understand very well this
PWM controls and also I am finding quite difficult to translate the
arduino code to PD. So after some headache i thought maybe someone has
already done this for PD?

thanks

Re: [PD] tab-abs

[Matt Barber]

Ah, yes, thanks!  I've said it before -- one of my favorite things
about list-abs is their use in pedagogy -- you can get "under the
hood" in them with music students and they don't have to learn C to do
it (each of the list-abs objects could be written much more
efficiently in C but it's nice to have them as abstractions, and
vanilla abstractions at that).  These iem_tab objects are great as far
as use-within-a-patch is concerned, though, so again thanks.  Maybe
I'll make my own abstractions for pedagogy.

Yep, all works fine here. Actually you needn't [pix_separator] in my

Yep, it seems there is a strange behaviour with [pix_mix] and
[pix_delay] from the same rendering chain. (That's why i use a [gemlist]
object to avoid this problem.)
If someone know why ?

made sure to force the CFLAGS to -m64, but the pd binary itself

hi Dan,

for me it was -fPIC had i had to insert at some places (no -m64) and 
at the and everything compiled successfully on my AMD, from these sources:


svn co
https://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/
pure-data
cd pure-data
svn co

https://pure-data.svn.sourceforge.net/svnroot/pure-data/branches/pd-extended/0.42/pd
svn co
https://pd-gem.svn.sourceforge.net/svnroot/pd-gem/branches/0.92/Gem


Andras
I didn't have a problem compiling ... it's just that the table bug is 
not resolved in pd-extended 0.41.4.  Using the current svn as you 
suggest also compiles fine and gives me a pd without the table bug ... 
but now I have the bleeding edge, as-yet unfinished gui  sigh.


Is there a patch for the pd-extended 0.41.4 pd source for the table 
bug?  That's all I really need right now as I can build the externals ok.

The iPhone uses the AudioQueue API for sound I/O, which portaudio does  
not support.

Hello,

I think this has been proposed before, so maybe I've missed it.  Is
there a library of abstractions for operations on tables akin to
list-abs?  If not, I'd like to consider how such a library might be
organized  A lot of the list-abs abstractions could be translated and
used for tables.  I could imagine for instance abstractions that would
fill tables with various kinds of windows, and some that would
implement such windows in a named table within the abstraction itself.
Also, there might be abstractions that would perform the operations
in-place, and some that would leave the source table intact and copy
the results into another table.  Etc.

Has this been developed and/or discussed already?  I would have a few
to contribute.

[PD] [PD-announce] Ardour Workshop + FLOSS Manuals Book Sprint, 23-27.11.09 Rotterdam NL

[Derek Holzer]

File under: tangentally related to Pure Data ;-) ---

Ardour Workshop + FLOSS Manuals Book Sprint

Hosted by: moddr_lab/WORM, FLOSS Manuals and Derek Holzer

Monday 23 November to Friday 27 November, 2009
Day session: 13:00-17:00 (GMT +1)
Evening session: 18:00-22:00 (GMT +1)
Location (physical): moddr_lab, Willem Buytewechstraat 188, Rotterdam,
the Netherlands
Location (online): http://en.flossmanuals.net/bin/view/Ardour/

Introduction to FLOSS Manuals by Adam Hyde
21.00, Friday 20 Nov at WORM, Achterhaven 148, Rotterdam
http://agenda.wormweb.nl/agenda.php?id=2888

Ardour is a full-featured, free and open-source hard disk recorder and
digital audio workstation software suitable for professional use. New
and experienced users of Ardour are invited to "learn by documenting"
during this combination workshop and book sprint.

A book sprint brings together a group of writers, editors and artists to
go from an outline to a published book in just five days. We will use
this format to give workshop participants tasks which they will learn to
complete in Ardour, and which they will then document for the Ardour
FLOSS Manual. This is an exciting opportunity both to acquire new skills
as well as share them with others in the form of a book!

The workshop will be split into two sessions: an evening session
focusing on learning the software and creating chapters for the FLOSS
Manual, and an afternoon session focusing on editing, proofreading and
correcting the workshop texts. At the end of the week, we hope to have a
beginner's manual covering these and other topics:

Introduction: What is Ardour?

Installing Jack & Qjackctl: Linux
Installing JackOSX: OSX
Installing Ardour: Linux
Installing Ardour: OSX

Participants who would like to join us in Rotterdam should sign up via:
works...@moddr.net

Interested remote participants should create a login on the Ardour FLOSS
Manual page: http://en.flossmanuals.net/bin/view/Ardour/
and communicate with us via the FLOSS Manuals chat interface on the
website or at: irc.freenode.net #flossmanuals
