[chuck-users] Has anyone written some additive synthesis ChucK code they might share?

I'm about to start writing a base class for additive synthesis in chuck, with overrideable methods to calculate sample-specific harmonic frequency, harmonic amplitude, and number of harmonics. I would then spork all the harmonics with each knowing its own harmonic number and each would go into a per-sample loop adjusting frequency and amplitude by calling these overrided methods at each step. I'm wondering if anyone else has approached additive synthesis and if so, if you used a different technique, and especially if you'd be willing to share your code. Forrest
