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).
Make sure the MIDI Channel of the External Instrument is not set to All. It should be set to only the channel for QC.
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.
Have you had any luck yet?
I’m also trying to setup my QC with a Logic session and having the same problems.
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.
Have you checked that ‘Ignore re-ocurring CC/PC’ messages is on?
having exactly the same problem. I tried having a single track with all midi. Randomly, QC goes crazy and enters a loop alternating bettwen presets
I monitored my project. some learnings:
- 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.
