I recently purchased a Quad Cortex. Everything was working perfectly fine for the first few days (except for the classic grounding noise), but during the second week, Cortex Control started malfunctioning. I had to restart it to sync with the QC. Then, a few days ago, Cortex Control stopped recognizing the Quad Cortex altogether. I have the latest QC firmware update installed, and I’ve also downloaded the latest QC driver for Windows. Simply put, the operating system no longer recognizes the unity in any way. I suspect it’s a problem with the QC’s USB output, and I’ve tried contacting Neural DSP, but I’m not getting any response from them.
I sent an email to Neural four days ago, and I’m starting to get concerned because I’ve previously reached out to them with questions and they’ve always responded promptly.
Yes, i downloaded the current Cortex Control and the Windows driver.
If you don’t hear back by Monday, DM your contact details and I’ll escalate to support for you. Have you tried using an alternate USB cable/port? Lastly, are you using the OEM power supply and or a USB hub? I would also suggest backing up the QC, perform a factory reset then test and restore your backup and test again.
Thanks for the support, my friend. Yes, I’ve already tried 1 USB cable, in addition to the original one that comes with the QC. I’m connecting directly to my computer’s USB port, without using a HUB. I’ve also already done a factory reset and it didn’t work. Thank you very much.
Have you looked at the USB statistics in the Diagnostics section of the Device Options?
This might show you if it’s truly dead and in need of replacement
Is this when you are trying to get audio from, or send audio to the QC? If so, the QC is doing absolutely nothing, so maybe you are not using the right USB routing on your computer, or the QC’s USB is fried.
I used it for a few days with Cortex Control and also for a few days as an audio interface, and I was able to do the USB return routing without any issues. However, after a few days, my computer stopped recognizing the Quad Cortex.
I have struggled with this (well known) issue many times.
In my experience it is not the usb cable. Steps to try
Shut down CC
On the QC open downloads and press the sync button at the top making sure that the QC has an internet connection
Shut down the QC
Open CC
Power up the QC
I have had to do this a couple times to get it going before. I think it’s some sort of sync issue between the QC and CC.
Yeah - one thing to check for sure is that your USB is actually showing up on your PC. On a Mac you can do that with the System Report. Not sure on a PC.
