sinusoids~ is an object created at CNMAT which is an efficient bank of oscillators. it is designed especially to work with sinusoidal track data from an SDIF file for time-independent resynthesis, however works equally with ad-hoc list control. its cousin is resonators~, a bank of two-pole resonant filters for simulating instruments, etc, also used with SDIF, IIRC.
More info at http://cnmat.cnmat.berkeley.edu/MAX/. There is source code for sinusoids~ and resonators~ in open sound world (osw.sourceforge.net), which may be available if anyone is interested (check the license, though
- its not GPL).
As for multislider, its basically like drawing in a graph and then getting the results in a list each, continuously or all-at-once each time you release the mouse.
Thanks Andrew, that's the exact ideas!!!
