Hey, I'm really on the cheap - and I was thinking of a cool simple project for a bassline synth.

I was thinking a wavetable oscillator (arduino or something) with an analog LPF, and more to be added after maybe.

The main problem is the wavteable oscillator, the only good arduino things I can find are that tabularasa thing and another project its impossible to find the code for, and the tabularasa seems really hard to get :/

So if you would have any suggestions for something simple I could build along those lines for the oscillator, that would be cool - It must have physical control though.

If there is nothing - what is a simple vco, that is musically useful that you would recommend for building? Thanks!

Someone recently posted an arduino-based wavetable oscillator on Instructables.com. Sine, square, saw, and triangle. I haven't played with this particular one, though.
One nice thing about Arduino is implementing MIDI is not too difficult. I made a small bassline-style synth using an Arduino, a Nicholas Woollaston VCO, and a Sallen-key filter. It sounded fairly good. I'm currently refining the circuit for single supply (9v) operation.
Anyway, good luck!
