How to know which command values to send from my midi controller to MG?

Hi @PaddyO

if you set your Airstep to send program change, you just need to save any preset on MG2 you want to have come first as 001(Preset name), and for the following 002(Preset name), 003(Preset name)…and so on. I did some (silent - no talk) video on connecting some pedals (Softstep and FC-300 but it is the same principle, if you want to have a look?
