MBSEQ V4 remote controlled by my new Button/Duo-LED matrix prototype.

The frontpanel hasn’t been created yet, and it’s difficult to push the mini buttons without button caps. But playing with this toy is already a lot of fun!

The BLM firmware is running on a dedicated PIC based core module and communicates with MBSEQ via MIDI. The optimized protocol is fast enough to achieve high refresh rates between 350 fps (if only a single line is changed) and 20 fps (if all 512 LEDs are changed).
