Freeze Pedal
This program was inspired by recordings of Mike Brecker where he would stack chords and play over them. That was done using looping programs, and this more specifically freezes whatever is being played and sustains it. I use my MIDI foot pedalboard (Behringer FCB 1010) as the controller.
My goal was to pack as much as possible into as little motion of the pedal as I could. What has to happen, in rough order, is 1) Turn on sustain, 2) Freeze the chord, 3) Transfer control of the chord volume / filter to the pedal, 4) Turn on a solo patch controlled by Breath, and 5) Reset it all at the end. In the process of making it, there were many little MIDI routing obstacles that had to be fixed. However, it works great and offers an incredible range of color and expression beyond what the EWI is normally capable of. Further, it can be plugged into most polyphonic patches and work without too much tweaking. My favorite feature to come out of this is that the solo patch can turn on Portomento and build chords separate from the Freeze patch, and their volumes are controlled separately (Breath vs Foot Pedal) at the same time.
