Thanks again - it turns out that it was a synthesiser problem.
In case anyone was wondering, I went back to basics and attempted to play
multiple notes through a simple patch. The synth (FM8) appears very much
polyphony. However I noticed by chance, the overlapping choppy problem with
chords that do not start synchronously (if you know what I mean) occurred with
only some of the preprogrammed sounds. So switching to a different sound on the
synth solves the problem.

Hi
I am trying to make a musical instrument for two or three people to play at
once
(fuller details below). Each person will have a controller, and I am
outputting
to a software synthesizier.
It works fine (some very fun responses!) with one controller, but input from
the
second sensor cuts short the notes played by the first (and vice versa).
Is there some way to make a MIDI note play for its full duration regardless or
whether another overlapping note is being played ?
(and if not, other suggested workarounds most welcome)
I thought maybe Noteout channel numbers was the way, but I maybe
misunderstanding how these work...
Indeed you'de probaly need to go for 1 midi channel per instrument (midi
input).
Additionally you need a polyphony of at least 3 notes in this case,
that is the synthesiser must be able to output at least 3 notes
all-together.
Hope this helps.

Many thanks

Fuller Details:
I am working towards a remake and electronic update of an earlier, fairly
popular dance floor sculpture:
http://www.chateau.eclipse.co.uk/robb/socialwhirl.htm
but hoping to transform people's movements on the rotating discs into sound
(though not expecting to wire up as many as 28 rotating discs for some time!
Two or three is enough for now)
So the basic set up is:
Gyroscope sensor in each disc/controller
Arduino
xbee
serial read in via a receiving Arduino (using Comport)
Pure Data (happy to share my patch if you like) FM8 (currently just able
to
use the Demo mode, so very open to alternative synthesiser suggestions!)
