Zipper noise in CC expression pedal control

I am controlling the AA with the Jomlabs Vlt1. Works fine with programm changes. I have set an expression pedal via the Vlt1 (so through midi) to control the wah or volume but I have zipper noise: you hear the midi steps in the signal. This is not the case when using an exp pedal on the regular AA expression pedal inputs.
How to solve this?

The midi expression pedal sends data in 7 bit resolution, which is 128 steps.
Your other Expression pedal is analog, and probably works at a minimum of 16 bit resolution (65535 steps).
Some midi cc# support 14 bit resolution, and I believe 32 of the available midi cc# do 14 bit.
It depends on your midi EXP pedal, whether you can change the cc# number, and if that supports sending 14 bit resolution (16384 steps).

That could be the issue. I will have to do some research.
I do not know which cc# supports 14 bit.
The Jomlabs Vlt1 manual is a challenge ;)
