I have bought a Tech 21 Midi Mouse for changing the preset sounds on my Minitaur.
However nothing happens when I try changing the sounds via the footswitch. This is an imperative part of my live playing as I use up to 4 sounds in one song.
Have you set the midi channel on the Minitaur to be the same as the Midi Mouse?
Hold down all 4 big buttons on Minitaur. They should start flashing. Now send something from the midi mouse and that will change the Minitaur to what midi channel it should be on.
