I might not explain my issue the right way. I only have one tap tempo source, the G2 switcher.
Signal chain is G2 (midi out) to #1 H9 midi in to #1 H9 midi out to #2 H9 midi in.
No other midi signal
G2 can send midi control message as a tap tempo midi output.
This function is designed to work on foot switch 7.
Instead of sending a programme change message, just once; foot switch 7 can be set to send a CC message in time with every tap of the switch.
A CC messages will be sent to the midi out in time with your foot switch press. In single mode and also on each press in stomp mode)
Does this clear up anything?
