As of firmware version 7.1.0, all the key and encoder product have channel change feature. Optimally, channel change with key would be better than encoder (detent encoder would be better than non detent encoder in this particular scenario)
How to set the keys to change channels
Enter WEB CONFIGURATOR
select HCI radio box and select MIDI channel - or +. That button will change the current channel + and -
Channel change limits
currently, it changes to up +3 and down to -3

- ALL LED OFF: 0
- RIGHT LED SLOW BLINK: +1
- RIGHT LED FAST BLINK: +2
- RIGHT LED STEADY: +3
