This all sounds great.
I guess there's also D/A converters.
And then combining the new audio signal with the old signal before the input to the filter (without overloading the filter input and clipping).
Am I right about that or am I misunderstanding something?

Because we already have those available in the existing circuitry. Then we also need another voltage control input for frequency control. So that MG and joystick pitch bend can control each PIC oscillator. Finally, we also need detuning (which can be digital control.
