|Unless you need the complicated scripting function that Per described, I'm not sure you really need an external device -- any MIDI device can send out patch changes. I use a simple trigger foot pedal to cycle through the song setups in my Drumkat, which includes patch assignments for my mixer, looper, and any other MIDI devices I might use. I have 32 channels of MIDI available for sending any sort of MIDI instruction (16 x 2 OUT ports). If you have more than 2 devices you can chain them together using their THRU ports.|
The drawback to my system is that there is no random access in calling up songs (at least not gracefully) -- the song order must be programed before each performance, and the pedal cycles through them in order. Perhaps an external MIDI controller would give you more flexibility here.
