Hi all,
This is a different idea altogether from the synth I'm building.
So I have this idea for a band-variable vocoder. Knowing how vocoders work and how to make them, I would need a variable capacitor in the nanofarad range for this to work. Now, I'm already having problems just finding a variable cap in that range, but it gets better: I want it to be voltage controlled as well.
Sure, it's always possible to make one, but I was curious as to if such devices even exist. The best thing I can think of is to use a capacitance multiplier circuit, which can of course accept a varying voltage and alter capacitance like that.
Any other ideas?
