Hallo
I created my own controller for vArranger. It is based on Arduino Leonardo. This version of Arduino can read and send midi messages via USB port.
Buttons are connected in a form of 4x4 matrix.
These buttons send midi values:
Note on: 90 xx 7F
Note off: 80 xx 00
Intro 1: 24
Intro 2: 25
Intro 3: 26
--- : 27 (not used)
Main A: 28
Main B: 29
Main C: 2A
Main D: 2B
Ending 1: 2C
Ending 2: 2D
Ending 3: 2E
--- : 2F (not used)
Start/Stop: 30
--- : 31 (not used)
--- : 32 (not used)
6.5 jack: 33 (jack on back side of the controller - for foot switch)
Each button has its own backlight. (LED diodes)
These are connected in a form of 2x8 matrix via MAX 7219
and they light up according to incoming midi messages.
Midi codes of buttons correspond to midi codes of LED diodes.

Hello v.muller, Congratulations, very nice achievement and especially the programming of functions on each button with LEDs. This realization only does the manual functions and the music becomes prettier with the variations, It's as much work as my footswitch in the work you have done.
I asked google translate for help. Sorry if it's mistranslated.
Very nice varranger controller.
C'est à mon tour de te relancé mes compliments sur ta jolie réalisation. 8)
