  1. This is what I call a drone type app, which there is no control in. But a great way to make some customize sound or fun and sounds pretty good.
    Just wish you could send in some CC , you could really do some strange things

  2. We should consider retiring the term “semi-modular” for synths with no changeable or replaceable modules. This softsynth looks modular but it is not. “Patchable” may be a better term, or just say “monophonic drone synth with 20 patch points.” (20 is just an example.) Yes, no, maybe?
