My understanding was then a misunderstanding. Thanks for sorting this out for me.

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.
