MIDI Keyboard Triggering Commands in Cubase 12

Hello everyone,
Greetings for the New Year!
First time writing here and need your help urgently.

I’m using Cubase 12 and do not use any MIDI Remote Controller as confirmed/shown by Key Editor.

I’m using a vintage Korg O1/W Pro keyboard for sequencing since day one.
Out of the blue, for the past 2 days, pressing some keys on the vintage Korg will trigger off certain commands in Cubase 12.
Eg. C4= Save or some keys will undo, nudge cursor, revert to old project etc.
I first discovered this as when I was inputting notes, I realized things will undo. Eg. Tracks moved back to where I moved them to.

I just realized, now, even opening and closing Cubase or any pop-up message from Cubase will trigger notes to the Korg O1/W. Some notes sustains and sometimes, it doesn’t.

Really difficult to work like that. I have no mapping or scripting (I don’t even know how to do that) and Key Editor confirms I have no remote controller attached.
The only other controller I have is a iCon Platform M+, which is turned off when I’m composing.

Any help and advice to resolve this will be much appreciated!

Regards,
Wei

The first thing I would try is to relaunch Cubase in ‘safe start’ mode and see if the issue persists. After this :

  • maybe check the Local on/off setting on the 01/W,
  • Be sure, in the Studio > Studio setup… window that all the items listed under Remote Devices (legacy) are not connected, this, for both MIDI input and MIDI output settings. Additionaly, check also that in the MIDI Remote manager window, there is no MIDI controllers ‘connected’.

Can’t think of another thing that could interviene, presently… :thinking:

HI cubik13,
Thanks for replying. I tried what you suggested:

  1. maybe check the Local on/off setting on the 01/W,
  • I hard reset my O1/W. Everything is fine, incl Local On/Off.
  1. Be sure, in the Studio > Studio setup… window that all the items listed under Remote Devices (legacy) are not connected, this, for both MIDI input and MIDI output settings.
  • Done. None connected.
  1. Additionaly, check also that in the MIDI Remote manager window, there is no MIDI controllers ‘connected’.
  • Done. None connected (see attached photo)

I tried with another synth, same problem.

  1. Safe Start mode
  • Only works when “Disable program preferences” is checked.
  • Solves the problem temporarily. Once I close Cubase and launch a project, problem comes back.

Conclusion: Source of problem has to be from Cubase, I just dunno what it is!

Gut feel is something to do with Preferences or Expression Mapping but I’m not even connected/mapped!

Any ideas anyone?
Much appreciated.

Double check the Remote devices. Maybe upload a screenshot of Studio Settings.

Do you have another midi program running at the same time? Check that if so.



Hi Steve,
Thanks for replying.
Above are screenshots of my studio setup.

Btw, what do you mean by “midi program running at the same time”, as in what sort of midi programs?

Thanks and regards.

Maybe I’m wrong, but I guess that @steve meant programs such as Bome MIDI Translator (MIDI real time messages processing) or MIDI LoopBe1/30 (added virtual MIDI ports).

Additionaly, could you provide us a screenshot of your Studio Setup > MIDI Remote pane ? Actually, it’s the more important one, in my view…

exactly, @cubic13. Also Vienna Instruments. @weiTPY should check everything.

Hi guys,

Thanks so much for advice. Still trouble shooting.

I don’t have any MIDI program running in the background. Not VSL either.
At the mean time, attached below is pic of my “Studio Setup > MIDI Remote pane “
& video of what’s going on.

Video:
Look at the mouse cursor in middle of screen at start of video.
When I press on my Korg keyboard:
C4 = Save project
C#4 = Revert
Eb3 = Channel Settings window
Last 4 keys on keyboard (E0-G0) = 4 audio tracks (not same tracks every time).

Video:

You won’t believe what happened. I tried everything including activating back old preferences thru Profile Manager, but nothing worked.

This problem even caused my usb MIDI connected Platform M+ mixer to produce a note when I touch any button on it.

Then I told my wife, who works in IT, and she said why don’t I just unplug the MIDI usb cable from keyb to PC and plug it in again (I only unplug the 5-pin MIDI ports end of MIDI cable when I tested with another keyboard, did not unplug usb end from PC).

I tried that and problem is gone.
Platform M+ also back to normal.
48 hours gone by now and everything is still working fine.

@cubic13 @steve
Thank you for your time and I’m sorry I can’t explain how Cubase 12 can suddenly go crazy like that and how it can be solved by just unplugging usb cable.

Source of problem is definitely Cubase 12.

Thanks again and Cheers,
Wei

she’s a keeper.
