Motivation:
The Circuit Tracks is a great little groovebox made by Novation, but it feels like they intentionally limited it's capabilities. They also sell the Circuit Rhythm, which has some of the features the Tracks is missing but lacks others. It has several MIDI outputs and would make a fantastic MIDI controller, but it's firmware only allows the intended use (many users feel this way).
First steps:
The Circuit Track's firmware can be updated using the Components website (and a standalone version) via MIDI Sysex messages. This led me to discover a bunch of their firmwares, all directly accessible with incrementing indices :)
NOTE: This link won't work without the authetication from Components: https://circuit-librarian.s3.eu-west-1.amazonaws.com/uploads/firmware/file/89/circuittracks-firmware-3891.syx
I was able to download the firmware as a .syx file (416 KB) and first tried running binwalk. No results. As I'm pretty new to this kind of reverse engineering I'm not quite sure how to continue.
As I understand it, the file probably is compressed and/or encrypted. Looking at it with binvis.io yields an interesting pattern, though I have no idea what to make of it or whether it holds any relevance:
So my question is: How/where should I continue? I'm thankful for any kind of pointer, even if it's related literature/resources so I'll have some clue :)
