[Stk] problems implementing polyphony...

[Gary Scavone]

Hi Patrick,

I think we need to find a profiler that can tell us where the bottleneck is with the FM classes.  The tricky issue might be that the problem doesn't show up using the simulator (according to Rumi), so we might then then have to revert to a trial-and-error approach.  The first think to try would be replacing the vectors of pointers with a simple array of pointers (in FM.h).

Regards,
