Midi Mapping in ITCH - Roll Loop

Has anyone else attempted creating a midi mapping for itch using bome's midi translator? I'm currently trying to create a mapping which will allow me to utilize roll loops in Itch.

The keyboard shortcut for roll loops deck A:
ctrl+alt+(54321)

The keyboard shortcut for roll loops deck B:
ctrl+alt+(09876)

I have mapped these keystrokes to various buttons on a midi-fighter but it does not seem to be replicating the same function (roll) in itch. Has anyone else tried this/can hazard a guess as to why this happening?
