Here is the result of some more experimentation around the paraphonic filters.
It's an attempt to get some aspect of Mutable Instrument Rings into the preen, so here are some new fx :
Plck : a karplus-Strong classic pluck algo, with a twist : the frequency of notes is taken from the Scala keyboard mapping
Plk2: same as Plck except midi notes only trig notes, pitch is set with the matrix
Moda: a simple 4 modes resonator, which can morph thru 4 presets, String / Wood / Gong / Cymb
