* rhodes

FM rhodes simulation for norns.

Adapted for norns from [[https://sccode.org/1-522][this supercollider snippet]] by user 'snapizz', which is adapted from [[https://github.com/thestk/stk/blob/master/include/Rhodey.h][STK's rhodey]], which Perry R. Cook and Gary P. Scavone adapted from a Yamaha TX81z algorithm.

Needs some visualization, and some parameters (tremolo and vibrato? chorus? brightness?). Email patches to [[mailto:gretchen@gnar.cool][<gretchen@gnar.cool>]].
