Our discussion made me think of other issues:
5. Stk imports respond to different messages
I often switch out STK instruments in ChucKing sessions, and occasionally
they differ as to which basic stk messages they respond to.
For example, Mandolin doesn't respond to noteOn, but it works with pluck.
At least Wurley doesn't seem to respond to noteOff.
It seems like many basic messages could be standardized in a common
interface for STK instruments.
This could be taken farther by generalizing over the different control
change parameters for orchestras of instruments, but you could probably
accomplish this better with a wrapper class.
Someone mentioned this at some point.
Will ChucK have a library of sampled instruments?
Or will performers construct or import their own and wrap them in code?
good much work,
