Does each member in the band have their own ME1 unit?
The ME1 acts as a stand alone small digital mixer for each musician.
They can create their own independent mix at each ME from the inputs present at the ME.
In the IO set up menu you can assign the inputs to send the all the ME unit the mix is created with in each ME.
Maybe some of the other band members could be talked into sharing some mixes.
Is everyone using in ear monitors or are some on stage wedges?
