Generating FM sounds in analog domain using the XR-2206


It is possible to use a sinewave generator to frequency modulate an XR-2206 or 2 XR-2206 IC one frequency modulating the other.


It is interesting how formants can be created resembling the oh, ah, ee vocal sounds just be rotary knob varying the frequency of the modulator to sweet spots and then increasing the modulating sinewave amplitude to create ah, oh, eh, ee (frequency band) formats etc.


Is it feasible to use an analog synthesizer frequency modulating another analog synthesizer for FM synthesis in analog domain?
