hello,
Sounds like a very interesting project.
It is my understanding that analog synthesizers generate the basic waveforms with additive synthesis.
Analog synths do subtractive synthesis: they start with square and triangle waves and pass them through filters to remove harmonics. The square and triangle waves are derived from the voltage on a capacitor that's charged and discharged at a constant rate. A fourier synthesizer does additive synthesis by adding harmonics together at various levels. Analog synths have trouble with this because analog oscillators generally don't stay synchronized.
