Firmware
I don't think I ever worked out firmware (.led files) upload, which I think would be useful (especially for linux people, since there is no Midi Control Center.)
Additionally, it would be cool to reverse the format and upload custom firmware to the Beatstep, so it can do completely different things. This may be challenging, since I think it is compiled for whatever microcontroller it's using, and I'll need to work that out first.

Here is the sysex for a firmware update to 1.2.0.3:
Beatstep Firmware upgrade 1.2.0.syx.zip
We should be able to compare with led file to work out what other bytes it sends.
It should be noted:
First it sends some bytes, then you must unplug/re-plug and the lights change, then it sends all the bytes, so there may be a couple steps in the CLI program for this.
