I gig using quad cortex with logic pro x. when I playback the project, I use midi control in logic pro x to control the quad cortex to change scenes and control the exp pedal.
Here’s the problem:
The quad cortex changes the scene or change the exp parameter WITHOUT I ASK, and it does these RAMDOMLY! This makes this device unusable.
For example, I programmed the logic to send the midi signal to let the quad cortex to change the scene from A to B at BAR 4, but sometimes, the cortex would change scene B to A at BAR 5 or BAR 6 etc.
I have tried using MIDI monitor app to see if that’s because my computer is sending random wrong signals, but no, my mac isn’t doing anything when cortex acting crazy.
I’m not seeing many people mention this, but if anyone knows about it, please help.
My computer is a macbook pro m1, and I’ve tried different usb cables.
Are you able to add screenshots of your MIDI program or even an export file?
So we can check this by using it with an other device/DAW (can try it on my QC using Logic Pro X and Cubase Pro 12).
A midi loop will make crazy things happen as well. Im not sure of your setup and setting so its hard to say. Im by no means an expert but I have had my share of issues that I had to figure out. As mentioned check your channels. If you have midi thru turned on try turning it off on the Cortex.

Hi guys, I’ve tried different ways to solve the problem, but none of these actually works, lol, but there’s some weird thing going on: every time we gig, the machine does not go wrong, but when I use it in my bedroom, it goes wrong sometimes, lol.
It’s still a mysterious problem to me, I’m still addressing it, will update if I have any further discovery.
every time you move back the song to restart in another point of the project, logic sends again the midi command to QC, and it sends them TWICE.
If you play without stopping, the problem does not happen. If you for any reason stop and rewind, depending on your preset (mine has a wah and some automation associated to that turning plug ins on and off), then it goes absolutely crazy and the midi monitor shows logic sending messages in loop to quad cortex.
the project completely stalls and I am not even able to stop it. I had to quit logic and reebot qc. I had to open logic in safe mode to be able to use it again.
something really crazy going on, but I believe the problem is in logic and not in qc.
I have completely the same issue!
Before I noticed this bug, I was using just scene switch depending on the song in my Backing Tracks project in LogicPro. It works just fine - I can start playing at any moment and have no problems.
But then I decided to have more options using unique presets for each song and put some preset change commands between the songs. Then I just got a light show of random switching knobs & landing on the wrong preset (usually from bank A)
After 15 months of having this issue, I finally find the way of resolving it, just simply disable the MTC (midi timecode) in the MIDI setting in Logic Pro X, and the crazy jumping around issue will be gone!
Hi! I’m only now having this issue. I don’t want it to last 15 minutes, let alone months… I have no idea about midi
If you disable timecode, surely you no longer sync the Timecode of Logic to the QC? In my situation I’d like to sync to the time of my Logic project, and also send preset / scene changes.
I got it working yesterday but didn’t notice the QC going nuts when I click around the timeline until today.
