Hi Ingo,

Thanks for the reply, [coll] and [poly] definitely look useful. However, I forget to mention I'm using Pd Vanilla :(

The information you provided is really helpful though, I'm thinking if I can try and replicate the functionality of [coll], maybe using tables or something similar. I tried a while ago but it ended up getting messy. 

If you can extract your method from your patch that'd be much appreciated. 

Thanks,
Joe

You can play as many notes as you want and it will always go back to the
last note played.
When releasing a note (that may not even sound ATM) it gets erased from
[coll] by using [remove $1(. To separate note on / off I use [nroute 0 2].
Note priority in this case is "last" which is all I personally ever need. (I
suppose other priorities can be set by using some sorting options within
[coll].)

In order to avoid other notes cutting off the current note I find the
easiest (monophonic) solution is to add [poly 1 1] right before sound
generation. This sends a note off to the last note played before starting
the new one and avoids double note offs.

I am using this in a rather complex patch. I’ll see if I can extract just
this single part of it if you can't get it to work correctly. Although I
don’t think I’ll be able get to it until next week.

Ingo

Betreff: [PD] Midi note handling for monophonic synth

Hi all,

I'm implementing a synth in Pd using midi/notein as an input. 

One problem I keep coming up against is handling note off messages. This
guy's blog post describes the issue
- http://kemptonmooney.com/2010/09/pure-data-midi-note-off-solution/

However, I think his solution is not exactly what I'm looking for. The
synths I use in Logic have note priority methods and remember all held down
notes (or at least 10). 

I wondering if anyone has managed to implement something like this in Pd or
might know where I can find out more about it. 

ddg.mono from Max
(http://www.cycling74.com/docs/max5/refpages/m4l-ref/ddg.mono.html) looks
similar to what I want - but I don't use Max and I don't think I can access
the source. 

Any ideas?

Thanks,
Joe
