Hi everyone! I have an Akai APC20. I’m using it with a DMX lighting program. Unfortunately, the lighting program only accepts input from a single MIDI device. This limits me to using the physical buttons/faders on the controller because they are mapped to one and only one MIDI address per control. I’m curious if I can hit one button on the APC20 and have Bome change the addresses of controls so that I may “trick” the lighting program into thinking it’s coming from one MIDI device. Perhaps that means to increment each address? Thanks in advance for reading!

On your APC 20 there is a button that you can push that I believe is called “Note Mode”. With this enabled your 8×5 grid sends different MIDI Note values than in “Standard Mode”

For instance in standard mode your top left grid button will send note 53 on MIDI CH1, but in note mode it will send notes 36 on MIDI CH1

In standard mode, the top row second button sends note 53 on MIDI CH2 but in note mode it will send note 37 on MIDI CH1.

So essentially you have a bunch of buttons you can re-use in Note Mode as long as they don’t collide with the normal mode MIDI mapping of the grid.

P.S. I don\'t know if you can put APC-20 into Note mode without host feedback but if you send it the below MIDI Sysex message it puts it into note mode (Mode 3)

F0 47 7F 7B 60 00 04 43 08 02 01 F7

Sending it this puts it back into the default startup mode (Mode 0)

F0 47 7F 7B 60 00 04 40 08 02 01 F7

I will have to investigate this more. Thank you!

Hi,

Yes, this is possible. You could set up multiple “layers” using Bome MIDI Translator Pro (MT Pro) software. and have one of the buttons, signal MT Pro to switch layers with the push of a button. Each layer would be a different preset within the software which could do different note/cc conversion.

The below Youtube tutorial shows how this is done, however, I’m using keystrokes instead of MIDI messages in the tutorial.  You would need to modify the project file for your needs which would probably be note-on and note-off MIDI messages. There is a link to the project file I used in the description of the tutorial.

I assume you also have gone in and out of note mode in order to achieve more buttons.

Wow, thank you for the quick response! I will most definitely give this a try!

What do you mean when you refer to “note mode”?
