Oh, while the output is 32-bit floating point, the "DAC" in the synth is 12-bit (that's what gives the crunch I want). Also it uses direct digital synthesis, so it isn't emulating an analog oscillator. DDS is easy to design, but has trouble with higher frequencies. The original computer was limited to 4kHz, and while I can tell this synth to play notes up to over 18kHz, aliasing starts just before 4k.
