I'm having an issue where after working fine for a little while, on my S9 the left deck channel volume becomes controlled by the crossfader rather than the channel fader (i've attached a video of this) the right deck works fine, i've just updated the latest drivers, firmware and updated to Serato DJ Pro which still hasn't fixed the issue.
I've logged a ticket with pioneer support on this one but just in case anyone has experienced this too i thought i'd post here

Honestly, any help or insight would be appreciated. Can't seem to find anyone with the same or similar issue to me
