I have a usb drumkit sending signals to pd through a pico device. It is part of an interactive art installation. I won't go into the details now but my question is this.

A note has been assigned to each drumpad. When it is struck the syncgrain~ object creates sonic particles of this note.
Will I use one syncgrain~ object per drumpad or one between all six pads with six varying parameters attached?
Any help would be greatly appreciated.
Thanks

if you only use one syncgrain~ you'll only have one voice, so it's a matter of whether or not you need the drumpads to trigger at the same time, or whether sound triggered has a lengthy decay that you want to let naturally fade as opposed to just cutting it off to play the new note. it's a matter of preference, although depending how much CPU syncgrain~ uses it might be more efficient to use only one.
hope this helps some,

Drumkit polyphony seems fairly obvious to start with. 4 voices. Two hands, two feet.
But remember that the closed and open hihats are mutually exclusive, and the cymbals
can run for a very long time. Like Ian says, CPU cost is probably your main constraint,
but my experience is that six voices is fine for a drummer.
