Hi Luke
according to page 35 of the manual you can't get the Axiom to send sysex.
It will send continuous controller (CC) though, so you can use my program to convert from CC to sysex.
Unfortunately this means you have to have a PC between the axiom and the DW8k.
There is a list of CC parameters in a text file with the download so you can program the axiom.
For any others interested, there is a new version of my program that can switch to either layout screen.
All the best
Royce
