Midi channel routing question - Skaht30h5 - 01-09-2022
Please forgive this noobish post, but I am having trouble accomplishing something that seems super basic. I’d like to use my Octatrack as a midi Sequencer for a variety of synths connected via midi, all routed through the MRCC. I’d like to sequence 8 different synths from my Octatrack with each synth corresponding with channels 1-8 on the OT’s midi out, but have the midi messages be received (on those other synths) as though they originated from channel 1 in each instance.
For example, midi channel 5 on the OT is destined for a Matrix 6, I send a sequence of notes over midi channel 5 to the MRCC (from the OT) and it routes the data to the M6 using midi out port 5 but the M6 thinks it is coming from channel 1 and not 5.
I have not been able to successfully configure my MRCC to do this despite having the manual open in front of me, googling, and searching the forum. I am not positive if this is midi channel mapping issue or if I should be filtering messages per port or what? Thanks so much!

Oh man, we totally made a special mod just to do this exact thing. Let me read up on it so I explain it properly and I'll walk you through it.

Channel to Port Mapping [C-P1]
Sub Page NOTE: There is no screen for this modifier because there are no setting.
If this modifier is added to a routing then only the MIDI messages on the channel number that matches the out-port number will be passed. The MIDI messages will be sent out on channel 1. All other MIDI messages are suppressed.
Example: if you have a routing (i.e. in-port 3 -> out-port 7) and there are inbound MIDI messages on channels 6, 7 & 8, only the MIDI messages on channel 7 will be sent. And they will be sent on channel 1 / out-port 7. No other message will be sent on out-port 7.
Example Continued: if you have an additional routing (i.e. in-port 3 -> out-port 8) with the same inbound MIDI messages on channels 6, 7 & 8, only the MIDI messages on channel 8 will be sent. And they will be sent on channel 1 / out-port 8. No other message will be sent on out-port 8.
Example Continued: if you have an additional routing (i.e. in-port 3 -> out-port 2) with the same inbound MIDI messages on channels 6, 7 & 8, no MIDI messages will be sent on out-port 2
Example Continued: if you have an additional routing (i.e. in-port 3 -> out-port 2) with the same inbound MIDI messages on channels 6, 7 & 8, and there is NO “C-P1” modifier loaded on that routing, then all the MIDI messages will be sent on their respective channels on out-port 2.
This is the modifier is best used when several MIDI channels are received on the same in-port and need to be “split” out to several out-ports. An example could be MIDI messages coming from a multitrack sequencer or something similar.
Note: this modifier was added in a semi recent fw update, so if you don't see it appear when scrolling though your mods, that may mean you'll need a FW update.

Thank you so much! Would the FW update you reference be 1.1.044? Or the last non-beta update?
RE: Midi channel routing question - Skaht30h5 - 01-12-2022
I want to extend another heartfelt thank you for your answers. I was using probably the oldest version of the manual (still said draft on the pages) and I had not updated the firmware. So, that was working against me and I didn’t have the good sense to investigate updating the fw initially. Using your clear instructions, I was able to get the outcome I had hoped for. Thank you again, sincerely!
