Quick Control altering volume as well as parameters

Can anyone help? I’ve assigned Quick controls to knobs on my Akai advance 49. The knobs do affect the desired parameters but also raise and lower the volume of the track. I’ve deleted all the unused slots in Generic Controller yet the volume is still affected.

Hi,

Is there any other Remote Device enabled in Cubase? What MIDI CC does your AKAI send? Can you try to record these MIDI CCs to the track? To make sure the MIDI CCs are (or not) going thru the QuickControls.
