Cool, I'll make a nice version of it tomorow (dog-tirered now) and share

I think they are great. Varying harmonics is a nice fresh way of modulating
timbre and of cource as long as you keep the number down there won't be any
aliassing so that's a nice free-be.

I've been meaning to try wave-shaping using that new function meant for
shaping the curve of input signals. that one should be capable of some nice
stuff though the CPU load at audio-rate might be high.

There's another way that I've been meaning to try to implement but the
principle is by a friend of mine and I need to check with him before writing
publicly about it. Either way that's a nice field to do some ChucKing in,

Yeah, I'm aware of that.... Actually I tend to work with that principle a
lot in my music, I'm realy into things like parametric EQ's with extreme
settings. You can do a lot in the way of intonation by controlling the exact
kind of impulse used. I did some pieces where I excited resonators using
traditional drum-kits. It's quite amusing how highhats can turn into ways of
bowing a "violin" that way.
