TC Electronic G-System

hello community,

I’m trying to control my TC Electronic G-System with the MC6 Mk2.
Calling up and changing individual presets is easy using PC commands, and turning individual effects on and off is done using SysEx commands, which I’ve already successfully figured out using the “Create SysEx Preset” function in the editor.
All that remains is changing individual effect parameters via a connected expression pedal.
SysEx data is also used here. However, a whole series of commands are generated there, namely a separate SysEx command line for each individual value from 0-127.
The G-System doesn’t respond to CC commands in this case.

The editor has 16 lines in which I can enter commands for the expression functions, but the “Create SysEx Preset” function doesn’t work here.

Has anyone already dealt with this specific topic, or is there a tutorial for the G-System?
