Hi MidiBoxers,
I am a little bit confused about the different
ways to make button/led matrices.
Which layout should i use to create a 128 button and 128 led matrix
for the Midibox-NG? What dis/advantages do they have and why?
Layout 1) SeqV4 wiring (64 buttons, 2x64 leds) + 2x DINX4 (64 buttons)
Layout 2) Midibox 128V3 wiring (128 buttons) + ?
Layout 3) BLM Scalar wiring with only 2 modules (128 buttons + 2x128 leds)
Thanks for your advice!
Best regards

Hi,
BLMs are very firmware specific, with BLM_SCALAR I’m trying to standardize this for controllers.
Layout 1) SeqV4 wiring (64 buttons, 2x64 leds) + 2x DINX4 (64 buttons)
A dedicated layout for MBSEQ V4 which I wouldn’t recommend for controllers since it requires a special firmware handling.
Layout 2) Midibox 128V3 wiring (128 buttons) + ?
Only difference between this and Layout 1) and 3) is, that there are no LEDs!
Layout 3) BLM Scalar wiring with only 2 modules (128 buttons + 2x128 leds)
Recommended layout since it will be supported by MBNG
Advantage: scalability is much better (therefore it’s called BLM_SCALAR), also a PCB layout is more simple.
Best Regards, Thorsten.
Hi TK,
thanks for your reply!
Now i can make further considerations.

Hi TK,
just to be sure: Are you talking about this matrix?

I’m not TK, but yes this is the BLM that is supported in the MB-SEQ, and that is not recommended for MB-NG based MIDI controllers.
Thanks for making this clear, ilmenator.
And yes, there is now definitely a PCB (and buttons) for sale from ilmenator. :whistle:
Cheers
