I have an Alesis quadra plus keyboard. It has 2 assignable pedal inputs both are set to control volume, but they both control the same MAIN OUTs. The keyboard is set to 'OMNI' mode. Does anybody know how to get it to pan between two patches layered by 1 or both pedals? Is there such a way to crossfade between 2 patches by vol pedal through MIDI? I want to layer piano and strings and be able to control the volume of each sound individually through MIDI processing- that way I could connect a CONTROL pedal with one cable instead of 10 cables to two volume pedals analog TRS style.
