Karyn, the standalone is omni. I found this out because I play a MIDI accordion where the right hand is channel 1, chord buttons are channel 2, and bass buttons are channel 3. They ALL trigger the synth. As you may imagine, in most cases I only want the right hand [piano keyboard] to trigger the synth patch.
scook, thanks for the links. I didn't know they existed. I'm going to investigate them.
