It looks cool, Nice little app. As a Reason user, I particularly like that it does everything through midi rather than VST. I agree with the point about notes: it would be quite neat to see this overlaid on a note lane. Still, adding new features is always easy to suggest. Well done on getting this far. I can't promise to buy (I'll have to have more of a think of a use case for me) but I hope you get some custom.

Pedantic nerd point: your beziers are not beziers days, are they? Looks like Catmull-Rom - they'll that doesn't quite make such a good brand-name.

I followed De Casteljau's algorithm, not Catmull-Rom. The control points that you drag are at t=0.5 for quadratic and t=0.25 and t=0.75 for cubic beziers. De Casteljau's algorithm gave me a bit more flexibility to validate and constrain the automation curves. Thanks for the feedback!
