I've been working on a (4) voice allocation system. I built a very simple sine synth with an very basic AR envelope around it. The main purpose of this patch is to test the voice allocation.

Oh yeah, it's built to be played with the computer keyboard. Note that the keyboard layout is belgian-dutch, which means AZERTY.

Any suggestions to improve it are welcome.

cheers,

Domien.

Nice using the table because it makes the allocated voices available to query. Works fine here.

I see you can detect if the action from the keyboard is a keydown or a keyup.
ok there is this [r $0-keybActive] controlling the [spigot]...
I tried something similar myselfe but didn't`get it to work. And where is ? I seam to be blind this morning ^^

the best thing is i open your keyboardpatch and my sampler is working *confused*
no bang for keydown but one for keyup... great ... my own chaotic code starts to scare me :o]

Hello Gorky,

well, the your looking for is actually the orange toggle on the front page, which is called $0-keybActive.

Note however that this is still something in progress (just up till the point where it works for me). For instance, there is no check whatsoever if a fifth voice was sent to the allocation unit. This is partially because i play it from the pc keyboard and windows only goes up to sending 4 different key events (lucky me). But if you were to change this to work with a midi kb, you would need to implement some form of voice stealing in the [pd getFreeVoice] subpatch. I tried this, but i guess it would be easier to implement this in straight c++ code, instead of with native pd objects.

Good luck,

Domien
