Ok I'll wait for the next release.
How I think it should work:
switch patch on button DOWN. Turn off after x seconds after button UP.
switch patch on button DOWN.
AFAIK, there's no need for on button HOLD (DOWN for x seconds) event.
Also, I just discovered that when connected via USB, if I hammer the button it eventually freezes on green and the bypass switch has no effect. This does not happen when powered via plug.
