ChordPlayer receives CC50-CC60 from pedal->button that will transpose the same pedal signals to ChordPlayer (CC63-CC73)?

Question

Hi

My first post and a newbie so please ignore my ignorance.

Stack:

• Pedalboard Roland FC-300
  • Out to Yamaha Motif Rack XS (5 pin din)
  • In from Edirol PC-50 (5 pin din)
• Roland GI-20
  • To iPad MDP2 (USB)
• Yamaha Motif
  • To Ipad MDP2 (USB)

I also have the StramByter and the MidiFire App

And more..(Infinity looper, Boss FS-6 and FS-5u)

I got this stack working fine playing both the midi guitar and the Edirol Keyboard sending midi msg to the Yamaha Motif.

I have created a layout for some Motif specific tasks that works fine.

I have added the Cord Player layout to my Motif layout

My Roland FC-300 is sending CC50 to CC60 triggers the chords in that Chord Player

What I would need is a button (hopefully receiving CC60) that will transpose the input from the Roland FC-300 from CC50 to CC63, CC51 to CC64, CC52 to CC64 and so on

I have tested the approach described in this article but I have not succeeded due to my lack of understanding how this really works.

Any input on such a transpose incoming CC from the Roland FC-300 button is much oblige

Thank you

Answer 1

When you want to process a stream of data, StreamByter is the answer.  MDP2 is about control.  Since you already have MIDI Fire, you need to hook up your layout so that the FC-300 MIDI stream is processed by this rule:

If M0 == B0 # B0-BF for channels 1-16
    If M1 >= $50
        If M1 <= $60
            Mat M1 = M1 + $13
        End
    End
End

The advanced controls example has nothing to do with what you need here.

You could do the remapping in MDP2, if you wanted to change ALL on a specified channel CC50 > 63 , etc.  But it appears you want this change to apply only to output from a single device, which is where MIDI Fire excells.  Each MDP2 translation requires two controls, one to receive the desired Cc, supercontrol, driving a second subcontrol with the desired output Cc.

Thank you for the response, I will try this.
Follow up on your response - If you wanted to change ALL on a specified channel CC50 > 63 , etc.
Would you be so kind and point me in the direction on how to do such set-up?
Much obliged, Thank you

re: "If you wanted to change ALL on a specified channel CC50 > 63 , etc."  - The SB codes does that, it needs to be placed in the MIDI network where all data you want changed goes through it.

You save me time and frustration,
