There’s a guy on here who has figured out the sysexes for M:S and M:C and something else too (A4 maybe) in order to do his own software (i.e. he hasn’t published any guides that I know of).
Will search and update here If I can find him .
EDIT: This is his thread on ‘Tensor’ which can create midi patterns for M:S and M:C. May be worth asking him if he ever investigated the Digitakt.
