There are a few firmware versions available for Tram8. I have the Octatrack firmware installed, which gives you 8 triggers + 8 CC->CV lanes. The default firmware offers 8 triggers + velocity instead. Anyway, here’s the def for the OT firmware. It’s possible I’ve midi-learned custom keys for the triggers, so you may need to change them to the appropriate values. 
VERSION 1 # Currently, this should only be 1.
TRACKNAME LPZW TRAM8
TYPE DRUM
# Can be A, B, C, D, USBD, USBH, CVGx (x between 1&4), CVx, Gx, or NULL

OUTCHAN NULL
# Can be NONE, ALLACTIVE, A, B, USBH, USBD, CVG, or NULL
INPORT NONE
# Can be x (between 1-16), ALL, or NULL. This definition will be ignored if INPORT is NONE, ALLACTIVE or CVG
