Neither sine wave nor FM was ever promised.
But once I made a notice about a request from a TalkBass user like that:
Effect on-off flip through MIDI: Control 69 (Hold 2) should be used for this. The third byte can be any value, a message will always flip between on and off.
Now I am working on update features. I wanted to implement this, but I realize this would not work the way as probably the user thinks it should. Any MIDI control pedal that I know will send the value 127 when pressed, and 0 when released. So, by the above definition the FI would turn on when you press down the pedal, but would turn immediately off when you release it, or the other way round. So, I think the definition should be correctly:
Effect on-off flip through MIDI: Control 69 (Hold 2) should be used for this. If the third byte is >64 the FI will always flip between on and off.
This way it will flip on or off whenever the pedal is pressed. Is that what you want, or did I misunderstand something?
