    Hello

    Yesterday i used my qu16 (latest firmware) on a live gig.
    I used six inputs (channels 1-6) and all the other channels empty.
    After approximatelly one hour of use, i saw faders 15-16 rised up and channels 15-16 are linked! But there are not in tha same level, for example channel 15 was 0db kai channel 16 -10db.
    I can’t image what whould happened if i have “used” that channels, with mics or instruments!
    Have you faced something like that?

    Nope…

    Could they have been knocked? Were they completely linked?

    So did you see them move up?
    Was there a network connection (i.e. could someone have been using Qu-Pad)

    Yes i saw them moved up, and no network connection, only multitrack recording with qu-drive.

    Very odd. We have seen noise on unconnected ST3 when the QUDrive has been in use, I wonder if this is similar cause?

    Very interesting, had a similar experience recently. Hooked up the Qu32 at home via both dSnake and LAN switched (see other thread) through the ethernet cable into the stagebox which only has a stereo input (23&24) and LR output used to play music (testing setup). Everything running through a UPS.

    Nobody was even close to the mixer and nothing connected through WLAN either but suddenly music was off and the linked fades 23&24 were set to bottom, and only these two. Observed this exactly once over weeks…

    QU32, and it was 23&4…

    That’s not the “right hand end” which was my suspicion wrt QUDrive interference…

    I also noticed this behavior (movement of faders) when i connect the mixer via usb to pc.
    I’m very confused and disappointed because is a SERIOUS bug especially for live use!

    “When I connect”

    Do you mean in the process of connecting, or when it has been connected?

    I’ve not seen either…

    I mean when it has been connected, not always but sometimes.

    While I do not like to dredge up older posts I do want to say that I have also experienced a similar issue with linked channels on my Qu 16. I was on a job in April and had channels 9 and 10 linked fully. While I was sitting there, not even touching the console, the two channel faders went from unity gain to -inf. The channels in question were not passing audio at the time and there were no scenes created. This is with firmware v1.7 installed.

    Yes..
    Happened to me ONCE only (QU32) just after I had connected to Mac “i think” as I have used both in studio.
    I thought mmm don’t wanna write home about that?
    too much work to do…
    so cold boot and …. all has been sweet on that system
    but I dont use that scenario QU32 every day
    however I do Use a QU16 nearly every day as a side car midi driver and never missed a beat.

    SO… i am wanting to know from… after owners have upgraded their firmware, do users ALWAYS do a cold boot?

    I know their are other threads about quirks, however my experience is or has been to MANDATORY do a cold boot after firmware update!
