Midi cc re-mapping?

I’m looking to change midi cc value coming from my foot controller to novation circuit. AU and without coding if possible.

Thanks

    mFX is easiest way to do this: https://apps.apple.com/us/app-bundle/mfx-series-midi-fx/id1451575127

    The free Streambyter is, albeit involving coding, very simple to use:

    BX 07 = BX 08 # remap CC7 to CC8
    BX 07 = BX 08 +C # clone CC7 to CC8

    But, if streambyter can do it what w> @rs2000 said:

    Thank you sir, that looks quite simple, or you are quite proficient at this.

    To be more specific though.

    I’m trying to make filter on Circuit’s bass synth to open to 127 by pressing a foot pedal. The foot pedal sends a fixed CC98 and circuit’s filter is on CC74.

    What would the code be for this specific scenario?

    @rs2000 and possibly go down to 50 on the toggle?

    What messages does the foot pedal send exactly?
    A CC message consists of Type, CC number and CC value, 3 octets in total.
    Hitting the switch sends one message, releasing it sends another.
    Use a MIDI message monitor like Hexler Protokol, mfxMonitor or MIDI Scope if you haven't yet.

    This is what I get from hexler. The switch is in toggle mode. @rs2000

    And this from midi scope

  • rs2000rs2000

    OK, so the CC number is 98 and the value toggles between 0 and 127.
    So what do you want it to end up like?

    On: Ch1 CC74 40
    Off: Ch1 CC74 127

    B0 62 7F = B0 4A 28
    B0 62 00 = B0 4A 7F

    A few details:
    B0 62 7F = B0 4A 28 # re-map CC #98 on channel 1 from 127 to 40 as CC #74
    B0 62 00 = B0 4A 7F # re-map CC #98 on channel 1 from 0 to 127 as CC #74

    B0 is "CC message on MIDI channel 1" (e.g. BF would be MIDI ch 16)
    4A is the hex value of 74
    62 is the hex value of 98
    7F is the hex value of 127

    Ok so what is the code I copy into streambyter? @rs2000 sorry for being dumb.

    Don't forget to hit "install rules". That's all 😎

    That's why I suggested Streambyter, for such simple conversions it's unbeatable.

    Works perfectly thanks, but....
    What do I do to invert the action?
    For example I want off to be 40 and on 127. Do I just swap 7F and 28 around?

    thank you @rs2000 for this short introduction to Streambyter code. I found a Scott DJX 20 MIDI controller in the trash, and was able to remap one analogue fader from CC65 to CC01, acting as a Modulation Wheel for my QuNexus keyboard. The other faders and knobs can be used as they are, assigning their CC’s to synth parameters. Also, in Streambyter, I added a line to block all note commands, because some faders send notes when they cross the middle position. Could be useful, these note commands, for some tasks, but for the moment I’m blocking all notes.

    Nice!
    What MIDI messages does the DJX 20 send when you turn a jog wheel forward and backwards slowly, then faster?

  • Phil999Phil999

    The two wheels, and also the two song selection knobs send note on events. That’s why I prefer to block note events, because the note off events are not sent from these wheels/knobs. In a MIDI monitor app I couldn’t quite see what exactly is sent, I guess these are only note on commands, and the faster you turn the wheel, notes get sent in shorter succession. Again something that could be used or translated for other software.
