shabby~ 'n shaffy~

shabby~ is a waveshaper using 11 Chebyshev polynoms to generate harmonics from an incoming sinewave. Each polynom will have a signal inlet to specify its amplitude in the signal. You can use shabby~ to have a decent additive synth that allows control over the harmonics in the course of a note at signal rate. But beware: it's not very fast.

shabby~'s little brother shaffy~ is now born. He uses only 9 Chebyshev polynoms and float inlets for scaling them. That is much faster than shabby~.

shabby~ was written by Frank Barknecht after finally getting his copy of Dodge/Jerse's "Computer Music" ;)

shabby~ uses the flext C++ layer for Max/MSP and pd (pure data) externals.
