This menu is for routing the Tracks' MIDI data. Each one of the 8 Tracks on the RK008 can hold MIDI data (notes, pitch, CC's) for 16 MIDI channels at once but via the output menu you can reroute these:
1. MIDI Channel
By default it's set to ORG, meaning that there is no MIDI channel remapping done. Typing a MIDI channel here will reroute incoming MIDI from any channel to the set output channel. This way you can use the RK008 as a handy MIDI switchboard. Just by pressing a Track you can reroute to a predefined MIDI output channel.
2. MIDI Port
MIDI port selects the physical MIDI output to route the MIDI to. You can use the digits 1-3 to select a specific output (OUT1, OUT2 or the RK006 via USB), or press 0 to send to all. By specifying outputs you can potentially drive a whopping 48 channels of MIDI gear.
