If you want results rather than a learning experience, consider upgrading to a Teensy 3.2 and Teensy Audio Adapter. The Teensy (ARM Cortex M4) has the power and I/O to produce quality audio. It still uses the Arduino IDE and APIs, and the audio library gives you a high level toolkit.
I have implemented several soft synths on the Teensy, both with and without the audio library. It works.
Thanks for the tip. I’d seen Teensy mentioned in my travels but didn’t look any further. At the moment I care about the learning over the quality but I’ll check this out once I understand the space better.
