Isolating different MIDI messages?

  Other than solutions like you've noted, the best one I've found is to use the free StreamByter AUv3. Its excellent.

  Thanks for responding! That’s a great idea - I hadn’t even thought of 3rd party solutions. I had picked up Mozaic awhile ago and hadn’t really used it yet so I took a look. Even with my minimal knowledge of coding, it was super easy to get the results I wanted.

  It would be great if there were a Drambo native solution, but until there is, this will do the trick.

  Cheers,

  @joelsquare If you don't mind, when you've done it, would you be so kind and share your code?

  I'm sure it will be helpful for others as not everyone can get their heads over coding their own stuff at all.

  Thanks for considering!

  I managed to isolate Note and CC messages for the 4x Quick Switch patch:

  For sure! It’s extremely simple:

  ————————

  To isolate Control Changes:

  
  

  
  

  @OnMidiCC 

   SendMIDIThru

  @End  

  
  

  
  

  ———————

  To isolate Pitch Bend:

  
  

  
  

  @OnMidiInput 

   if MIDICommand = 0xE0

    SendMIDIThru // 

  endif

  @End 

  
  

  ——————-

  
  

  It’s literally that simple! I’m no expert on coding so it’s possible there’s even simpler ways to do it, but for now, this is accomplished what I needed to do. Most complicated part for me was figuring out the correct hex address for pitch-bend. Mozaic defaults to sending NO messages through, so these simply say “ upon receiving a control change message, send that through” and “upon receiving a pitch bend message (0xE0), send that through”

  Oh, to be clear, this happens within Mozaic by Ruismaker

  @joelsquare - here's a streambyter version:

  # Block selected midi message types
  # Comment out the message type(s) you want to pass through.
  
  # 8X = XX +B  # NOTE ON
  # 9X = XX +B  # NOTE OFF
  
  BX = XX +B  # CC
  EX = XX +B  # PITCH BEND

  @joelsquare - to save having to load several scripts, it might make sense to use channel conversion per message type, then use channel filter modules to let through midi per channel.

  btw, there are some Mozaic scripts on patch.com that filter by selectable midi types. Here's one: https://patchstorage.com/midicensor/

  Just for fun, here's a Streambyter script with toggle buttons for different message types. ON = Block. Default = OFF.

  # Block selected midi message types
  # Button ON == block
  
  IF LOAD
    SET NAME Message_Blocker
    SET Q0 Note_OFF +TOGGLE
    SET Q1 Note_ON +TOGGLE
    SET Q2 Poly_AT +TOGGLE
    SET Q3 CC +TOGGLE
    SET Q4 PC +TOGGLE
    SET Q5 Chan_AT +TOGGLE
    SET Q6 Pitch +TOGGLE
    SET Q7 +HIDE
    
    ASS Q0 = 0 0 0 0 0 0 0 0
    SET SLIDER_DISPLAY 1
  END
  
  # Force Note-ON and Note-OFF equal
  IF M0 == F0 7D 01 00
    ASS Q1 = Q0
  END
  IF M0 == F0 7D 01 01
    ASS Q0 = Q1
  END
  
  # Calculate the index into the control array
  # from the message type
  MAT L0 = MT / 10
  MAT L0 = L0 - 8
  
  # Block if the control array value is 1
  IF QL0 == 1
    BLOCK
  END

  Thanks for these! I’ll check them out.

  I’m back to the struggle of trying to find a Drambo-native solution. My latest project requires being able to open Drambo as a plugin within Logic, so Mozaic makes that a bit trickier.

  Yeah, this is a great script. Simple and effective. Thanks again.
