[sdiy] Additive Synthesis questions

[Paul Schreiber]

>I can't think of a single SIMPLE sine wave generator,

Not in the analog domain. But in a $13 Xilinx Spartan 3e you can put in 128 
independent sine wave NCOs no problem. With the $28 part you can stuff in 
all the multipliers (VCAs) and mixers (adders) to make as big of an additive 
synth you could ever try to control :) The control would be the hard part. 
All the hardware could fit on a pc board 3" x 5".
