Q: I want to control more than one 13-pin box at a time with my MIDI guitar. Is there a splitter or switcher or something I can get to let me do this?
A: Yes. The Roland US20 will let a GK-equipped guitar control two 13-pin devices at a time; for example, you could combine or switch between a GR-20 Guitar Synth and a VG-99 V-Guitar system.
