Can I use the Roland MC303 groove box as a MIDI controller? How do I get it to transmit?
Yes. Here’s how:
1. Hold SHIFT and press button 14 (Out/Assign)
2. Press each part button, and turn the button to EXT (this sets that part to transmit to MIDI out)
3. Parts 1-7 correspond with MIDI channels 1-7, and R corresponds to Rhythm, MIDI channel 10
