I just went and plugged the pedal midi out into a cheesy little Yamaha
midi capable keyboard. The pedal does as Steve said...it changes patches
in the keyboard when I change banks on the pedal.

I knew there was a GOOD reason I became a picker and not a keys
player....MIDI is a PAIN!!!

Surely there must be a simple way to have some app in existence
interpret that patch change data into something I can use as controller
data or "note on/ note off" even. Thats all I need to be able to toggle
a volume or similar parameter in AMS to control output of LADSAP plugs.

Hell...I'm beginning to think spdt switch on the audio cable!! This is
too hard! :) But then I will learn nuthing willnt I!!
