Hi Olaf,
if you want to control the faders of the QuPac with haptic faders, I’ recommend connecting a faderfox UC4 to it, there you have at least 8 faders and 8 encoders on a very small footprint and you can configure the thing to any channel and cc.
I’ve postet a tutorial on how to finetune the Rytm here:
If you want, you can copy and paste it to your How to Guide.
