So years ago I had an idea to make a synthesizer using 555 timer ICs as the oscillator.

Now, with an Arduino, this should be much easier.

I've got two main possibilities to control it- a resistor/capacitor network which I activate/deactivate parts of as needed, or a digital potentiometer.

I think the latter is the only viable way. Otherwise I'm looking at needing something like 40 resistors and that would be a nightmare to wire up.

Will do more research on this and hopefully come up with a good design by the time I'm ready to order the parts.
