Custom Firmware

It would be cool to program the Beatstep to mostly work like it does with regular firmware, but also have some of my sequencer ideas in the firmware itself. This would allow you to keep using the MIDI manager or CLI, but also use it as a beat-sequencer without a computer. Maybe some magic button-combo could change the built-in sequencer to work differently.

This will require:

- Reverse-engineering the led format (see #6)
- work out how to compile my own code for the device: figure out the chip they are using, etc
- write all the current device features (update mode, all the mapping sysex, send midi messages, etc)
- add new sequencer modes to code
- encode my custom firmware as led file
- upload to device

I think a first step would be getting it to just run simple custom code (blink lights, etc), that allows led-file updates (so I can put it back, and dev easier (no JTAG header needed, etc.)

Comienza con el issue #6 para entender el formato LED y, después, inspecciona la CLI existente y el flujo de actualización del dispositivo. Determina cómo se podría compilar código personalizado sencillo para el dispositivo y subirlo como un archivo LED, tomando la restauración del firmware original como criterio inicial de finalización.
