Create pass through only from 1 incoming channel

I have an application where I want to take any incoming note on channel 4 and pass it directly out to channel 4 using the default midi connections. I know you can do direct pass-thru with the router feature. But I want to do it only when incoming notes are on a specific incoming midi channel no matter what incoming note is there. Any help? Thank you.

Hi, the easiest way for me is to create 3 translators and have no pass through routing. The first translator take any incoming 3 byte message. We use rules to look for the MIDI channel. If it is note MIDI CH 4 (03) then it exits, otherwise it passes the message along

I then to the same thing for any 2 byte messages. For 1 byte messages, there is no channel information so we just pass them through.

Here is a log of my test.

1: MIDI IN [Bome MIDI Translator 2 Virtual In]: 90 23 45
2: MIDI IN [Bome MIDI Translator 2 Virtual In]: 81 24 45
3: MIDI IN [Bome MIDI Translator 2 Virtual In]: B2 43 43
4: MIDI IN [Bome MIDI Translator 2 Virtual In]: B3 44 44
5: MIDI OUT [Bome MIDI Translator 2 Virtual Out]: B3 44 44
6: MIDI IN [Bome MIDI Translator 2 Virtual In]: C0 00
7: MIDI IN [Bome MIDI Translator 2 Virtual In]: C1 01
8: MIDI IN [Bome MIDI Translator 2 Virtual In]: C2 02
9: MIDI IN [Bome MIDI Translator 2 Virtual In]: C3 03
10: MIDI OUT [Bome MIDI Translator 2 Virtual Out]: C3 03
11: MIDI IN [Bome MIDI Translator 2 Virtual In]: F8
12: MIDI OUT [Bome MIDI Translator 2 Virtual Out]: F8

I have my aliases set up as follows. You will need to set them up for your actual devices.

Hi Steve,

It has been awhile on this subject but I need to do the same thing for channel 10. I went into the rules where it said channel 4 and changed it to channel 10 but it did not work. Am I missing something? What exactly do I need to edit in order to change the channel in Bome from 4 to 10 (or any other channel in the future) to address the note pass through?

Thank you.

Hi, please see that attached project. The only thing I change is the comment on line 3 and the channel on line 4. Since MIDI 1=0 , then MIDI 10 =9.

I changed the same think in the rules of translator 0.1 and 0.2.

// get incoming MIDI channel into rr
rr=oo&15
// Only pass if MIDI CH 10
if rr!=9 then exit rules, skip Outgoing Action

Hi Steve,

Thanks for the quick response! I am not sure I am understanding the numbering. ‘Since Midi 1=0, then Midi 4 = 9’. Then what is midi 10, or 12 or 9?

Also I wanted to actually pass the entire midi command to an outgoing midi message, so I could set up on translator to:

  1. check and see if the note is coming in on channel 10.
  2. Then if it is channel 10, pass the midi command: channel 10/Incoming [Note] to the outgoing message.

Sorry if I am not explaining myself correctly.

Thank you.
