In an effort to be able to adjust the internal settings of the Keystep, but not having regular access to a PC capable of running the MCC, I laboriously copied all the SysEx strings from a window within the MCC, and then tabulated it all into a . PDF.
I posted this on the Arturia forum, and it was downloaded a few times, being useful and all.
However, the post seems to have been removed, possibly Arturia aren't happy with the prospect of people tinkering with the values.
Anyway, I'll leave it here for now.
