examples of using *warp* and *transpose* in an instrument

Programming and Development Nyquist

I’ve designed an instrument that (theoretically) offers independent control over (attack / decay / sustain / release) and pitch. If I understand correctly, it would be idiomatically correct to use warp and transpose (respectively) to control those parameters. As I imagine it, by default the instrument will play a 1 second note on middle C. If you want to sharpen the attack or stretch the release, you modify warp. if you want to change the pitch, you modify transpose. Is my understanding correct?

If so, are there any example instruments that do this? I believe that the :next method is where I look at those things…

(Oh, and is this the best forum in which to ask this question, or is there a more hard-core Nyquist forum that I should know about?)

Thanks in advance…

There used to be a mailing list for Nyquist, but that has fallen into disuse, so this is probably the most “hardcore” forum that is currently active.
I’ve not worked with Nyquist instruments much myself, but there are a number of instruments that are shipped with Nyquist that you can look at:
Physical models: http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#index481
Piano synthesizer: http://www.cs.cmu.edu/~rbd/doc/nyquist/part15.html#index1207
Physical Model Functions: http://www.cs.cmu.edu/~rbd/doc/nyquist/part8.html#100
“mini moog” library: http://www.cs.cmu.edu/~rbd/doc/nyquist/part15.html#180

"warp "is hardly ever used directly. One is more likely to use a “stretch” or “duration” parameter that indirectly implements warp.
