Is there a way to assing an aux swtich to always control the mix, for every preset? I would like to be able to click on the Aux, and have the Mix go to 75-100, and when unclicked it would go back down to 40-50%.
In H9 Control if you click on Pedal in the bottom menubar and then Aux Switch Mappings, you'll see a pedal function 'Set parameter 1'. You can use this to have the aux switch toggle the mix value between two settings.
