Cool, I like the split keyboard feature.
I've not really thought about a license tbh, I'll look into which one would be best and add a note about that. I don't really mind what anyone does with it so maybe MIT would be the one.
Cool. Great to meet you virtually, btw. Your web audio synth is awesome. Adding the oscilloscope made me appreciate how your different patches generate their unique sounds. And I added a few preset patches I liked too.
