I just quickly demoed it and I think there is a big opportuniy missing: The option to edit Layer A & B at the same time. If you want to have similar designs on layer A & B, only needing differences here and there, that would be great. Like the "Edit Button B Blinking Mode". Also copying A to B is probably missing (not sure).
Also but I'm not sure about this one: Is it only possible to start a project with one Synthesizer ? Is it not possible to use the editor with several synths at the same time ?
Thanks
