Advices to check Bank and Prog Change send :
You can send them by double click on stop.
Check it with a midi monitor (ex miditest on pc, midipal, midibud…)
IMPORTANT : The Ot send midi messages only once if they are similar. That’s why it doesn’t work everytime. You have to change settings to send it again, or 2 clic on stop for Bank + PC.
I use Event Processor Plus, that allows me to convert any CC to any PC. Random PC kingdom !
