RE/[jmsl] DimensionNameSpace and JMSL 103

[jmsl at music.columbia.edu]

Hi James

I  like it that you leveraged off a working demo to solve your problem.  
But handleControlChange() is already public (it is a public method in 
the MidiListener interface) so I am not sure I understand what you 
really did?

Check cloneDataSetPitch() to see how I set the pitch in an existing 
array.  Otherwise...
double[] data = new 
double[myInstrument.getDimensionNameSpace().dimension()];
// alternatively if you know how many dimensions you have, double[] data 
= new double[7];
data[0] = someDuration;
data[1] = somePitch;
data[2] = someAmplitude;
data[3] = someHoldTime;
// data[4 .. dimension()-1] correspond to synth inputs unique to your 
synthnote like "rate", "feedback", "wiggle", "cutoff", etc
