Hello again everyone!
   OK, having read and meagerly replied to the thread about polyphonic 
portamento, I thought, that this would make a nice and very useful feature in 
csound. Voice-tying. Same woyuld go for voice stealing.
   Csound's current behaviour with maxalloc is to just ignore further events 
after that. Which certainly is not that behaviour used to from other typical 
hardware or software synths. I mean those, that are typically associated with 
attached keyboards and sounds for relatively popular music only. There you'd 
suspect the next note-on to steal a voice, usually turning of the first 
allocated voice.
   So: Would those, who use csound everyday, perhaps think it worth it as well, 
to have something to control csound's behaviour in that way. Allowing for 
voice stealing and allowing for some sort of voice tying between instruments. 
There are techniques to achieve that right now, I am sure, but for someone 
working with MIDI controlled typical synth instruments - i.e. melodic - things 
like voice stealing are a piece of daily living.
   Kind regards and thanks for following my ramblings so far
            Julien

I had implemented a voice stealing algorithm in prior email to the list:

http://csound.1045644.n5.nabble.com/Realtime-midi-audio-and-polyphony-td1099266.html#a1099270

It was a bit basic, and not looking at it thoroughly, but assuming
since I wrote it 5+ years ago, I'd probably use some of the newer
conventions in Csound now.  It may be worth looking at though.

Hi Steven!
   Thanks for this. I must admit, it does look a bit long for such a "small" 
task. This is no critique of your work, it's brilliant and certainly flexible 
enough at its base to suite more complex algorithms, but for me as a 
simple-minded orchestra writer it looks like a lot of trouble for a feature, 
which I've come to know and rely upon quite a bit.
   It's no criticism of csound as well, and yet it would still be lovely to 
have a simple opcode for this, which would allow for the typical three 
algorithms (last, lowest and highest note priority) and which would allow for 
a release phase of all those envelopes, which allow for it to run through 
instead of directly cutting the note. This might not be true hard synth 
behaviour, but something like it - at least as an option - would be absolutely 
splendid.
   I will keep your example around here though, Steven, for I think it should 
very much serve for the time being.
   Warm regards
             Julien

I have a similar solution in the Hadron orchestra too
(partikkelaudio.com,
http://www.partikkelaudio.com/plugin_free/HadronSource.zip, in the
file inc/midi_note_instr.inc),
it was written "prepared for" polyphonic (mono) voice allocation but
currently only one voice is used so some bits may be missing.
I probably worte it at the time this was last discussed and inspired
by Steven's solution it uses tables to keep lists of active notes in a
similar manner .
Agreed there's a lot of code for a "simple" thing,
so perhaps an opcode for this sort of thing would be nice.
The opcode could be used in a control instrument, together with an
event opcode to generate the audio generator instrument events.
this way release envelopes etc should be more or less straightforward
in the audio generator instr.

Hello Aaron!
   Thank you for your work. I think you might have been even better off basing 
your work on Steven Yi's implementation of simple voice stealing. But still 
with "the same note" feature you certainly got one, that wasn't present in 
that solution for sure. The turnoff2 opcode also seems a very good choice.
   I will try it and see, what happens and what I might think of, which is 
probably not too much. :-(
   Warm regards
               Julien
