This is very good work in this space. Rebirth 338 was the bees knees tipping point for virtual analog on a PC. We have been seeing numerous things that hint at the direction of where things can end up and this is a good way to establish cred for browser-based audio generation.

Generally good piano roll implementation, controls. It'd be nice to have a master fader and possibly a compressor amongst the effects implmemented.

I'd also love a swing parameter.

Something I've noticed is that knobs with a touch screen can be rough since your digit is covering the visual feedback. Maybe a single vertical line indicator next to the knob could mean you would know where you are and how far you can go when tweaking one?
