Control Mackie FLIP button with general midi

I want to send to SD+ two mdi commands:

- one to set ON the FLIP button
- another one to set it OFF

It seems that the note for controlling the button is note on 38 (value 127 on / value 0 off).

I can't get it works.

Do you know how I can do it?

Thanks!

I guess it's the Mackie FLIP button you mean.

Mackie buttons aren't 127=on, 0=off; they work as a computer keyboard, i.e. when you press the button it sends 127, and when you release the button it sends 0.

So there is no way to set it ON; you can only send a 127+0 combination to toggle its state. If you want to make sure the state is the expected, you need to keep track of the current state yourself and only toggle if it's wrong.

Thanks for your reply.

I can't toggle the Mackie FLIP button.

I have tried to send:

- note 38 on 127 + note 38 on 0

- note 38 on 127 + note 38 off 0

- note 38 off 127 + note 38 off 0

Anything toggles the FLIP button.

What am I doing wrong?

Thanks.

50 is the note number that controls the Mackie FLIP button.

Sending note on ch 1 D4 (note50) velocity 127 toggles the Mackie FLIP button.

Receiving sysex 90 32 7F indicates the FLIP button is ON (sysex is note on ch 1 D4(note 50) vel 127)
Receiving sysex 80 32 40 indicates the FLIP button is OFF (sysex is note off ch 1 D4(note 50) vel 64)

Edit: These values are tested and working fine with Cubase 12.

Yes, note 50 is correct. I forgot to set the correct middle C when checking the note number. It's D2, D3 or D4, depending on how you set middle C. So it's a bit dangerous to use note names.  

The flip button is in the daw-specific area, so the note number is probably daw-dependent, even if it seems pretty standardized.
