A Moog Sythesizer is an example of Subtractive Synthesis.

Hi,

Is subtractive synthesis called what it is because sine waves are
subtracted from a signal? e.g., signal - (sin(2 * pi * t) * amp)? I've
thought about this for a while, because I've been using Python's wave
module to create computer music "the hard way" by "drawing" (using
numbers and functions instead of ugens) different waveforms (sort of
like a combo of GENs 7 and 2). The algorithms in Csound seem like
they're optimized, but then again I haven't looked at them closely
enough to be sure.
