Tod Kurt (todbot)<p>For the last month or so I've been working on seeing how far I can push CircuitPython into emulating a TB-303 bass synth. With the new audiofilters library, you can "stack" filters to make two two-pole filters seem like a 4-pole filter, getting close to that squelchy sound we need.
