OpenCL-based ChucK UGens would definitely be interesting...
Kassen that Mac OS X now uses floats all through in the audio pipe  
line. Wouldn't that be great for ChucK, too - avoiding overflow over  
combined UGen amplitude 1.0.

Do these track the overtones? - When checking the spectrum of an  
oud, I
noticed that the fundamental is missing if one passes to new note  
by
shortening the string with the finger against the board without  
striking it
with the other hand.
Well, fft as such doesn't "track" anything.
In a past thread, when discussing using GPUs for getting extra  
computing
power, I forgot to mention this FFT that achieves 144 Gflop/s on  
the now not
so new GeForce 8800GTX:

Haven't looked at details, but I think it can be used as just an  
added
parallel computing resource.
