Dan has very kindly helped me through a problem that I encountered when trying to trigger some old hardware MIDI sequencers such as the Yamaha QY70, Boss DR5, and Roland MV8800 and MT300S. Unlike the "start/stop" button, the "continue" button will not send a stop message at the moment when it is disengaged. In order to achieve this, I have created one "continue" button with a range of 0 -> 127 and a second 'excluded' "continue" button with a range of 0 -> 1 that is the supercontrol of a "start/stop" button with a range of 1 -> 0 (by means of inverting range) with 'send on only'. Both of these "continue" buttons are trigger by the same supercontrol on my pedalboard.
Give it a try and let me know if it works for you!
