I'm working on a setup where the pitches of a PD patch are controlled by the computer keyboard using the bottom row keys (Z - , ) and a few of the second row keys (S, D, G, H etc.) set up like a piano keyboard.

The keyboard control patch is basically a [key] connected to a bunch of

[sel #] <---# is obviously the key
|
[#( <---# is the pitch in HZ

This feeds the pitch into the synth patch.

How would I have to alter this to be able to press more than one key at a time in order to play multiple pitches?

I can set up the synth patch to play multiple pitches, but using the keyboard, I only register one key at a time

I hope that was clear enough..
Thanks

Just think of it as being similar to how MIDI works: there is a note-on and note-off for each pitch. When a note-on is triggered, the pitch continues until it gets a corresponding note-off; another note-on from a different pitch won't affect it. So if you just use [key] to trigger note-ons and [keyup] to trigger note-offs (or use [keyname] to do both) and couple them with a pitch, you can handle it like MIDI data. Then just use [poly] to handle the polyphony.

holy crap... i didn't know [poly] existed.

I probably could have done that myself

thanks man!
