Describe your issue:
I was running a drum track through the USB input into the QC and through the output into a bass amp. I wanted to run both a bass and guitar through the two main inputs of the QC and jam in my living room with my friends kid who was over for a visit and is learning to play guitar.
When we went to play both inputs were cutting in and out, almost but not entirely cut off, very very quiet, with buzz and noise.
It was happening on both inputs jacks 1 & 2 at the same time and despite switching cables.
The issue went away and hasn’t returned since I switched presets, suggesting a software issue to me.
But this is mortifying to me, as I have a standard electric HH and semi hollow body electric that I want plugged into seperate inputs all the time for separate gain as one is active.
Steps to reproduce your issue:
Plug the USB into a computer and select the USB outputs on the computer to get audio from your browser into the QC
Playback YouTube drum track on the QC through an amp
Try to play two instruments over top at the same time out the same amp, using multi out for everything
It sounds like a USB issue to me. I’ve had USB problems with so many audio devices. They can be so intermittent and elusive. I had a guitar processor that I bought for practice and to combine with USB audio from my laptop. Some days it wouldn’t work, no matter what I did, the next day it would work flawlessly. I realize that it can save a generation of AD/DA and a little latency but, for me, it’s often not worth the headaches. Fortunately, I have multiple mixers and interfaces to alow me to use analog connections when USB fails. It could be hardware, could be software, could be that Jupiter is misaligned with Uranus. I understand your frustration. Hope you find a solution.
was the USB/YouTube signal OK? It was just the audio input channels from the instruments that were weird? Were the signals possibly ‘ducking’ each other thru the shared Output into the amp? If you played each input source individually, were they still intermittently dropping out?
I guess none of that really matters though, if it all resolved when you switched presets (unless something was configured strangely/differently in the problematic one) Were you using the factory power supply?
Have you contacted Support@neuraldsp.com yet? They’ll need to know in case it was some sort of software issue. If you can’t duplicate the issue, it might be tricky to diagnose, but you could send them a diagnostic report from your QC at least. Better to catch it early if it’s a developing issue.
