Cubase 15/HALion 7 CC/MIDI Volume issue

[“Crosspost” from Virtual Instruments]

Cubase 15.0.10
HALion 7.1.51.1043
Macbook M3 Pro, Sequoia 15.7.3
Apollo Twin X
18GB RAM

TL;DR: After installing the latest Absolute 7 update, the volume sliders on individual MIDI channels in HALion 7 zero out immediately upon clicking on a MIDI lane or inside the virtual instrument. This seems to only happen inside Cubase, the standalone appears to be behaving okay.

What it says on the tin. Here are some particulars:

  • Fresh reinstall of HALion Sonic after Absolute 7 upgrade; also re-installed the Cubase program files.
  • HALion channel fader in the MIX tab continuously snaps back to zero.
  • Happens with no MIDI devices connected to the computer
  • Happens with Cubase just sitting idle
  • MIDI signal reaches HALion fine, audio output because of constantly lowering volume slider is the only issue.
  • Happens on every file I open, including those that came with Cubase.
  • The “R” for “read” automation button is **not ** active.

I can pull the volume slider for the sound all the way up, but as soon as I move the cursor away from the fader, it slams back to zero. The entire time I’m hovering the cursor over the volume slider (not clicking), the old-school-looking MIDI indicator above is it highly active.

My novice-to-Cubase observation is that Cubase seems to be sending some kind of CC automation that is slamming volume to 0, but I am completely stumped. All my other virtual instruments are working fine. and when the volume slider is up, everything sounds great.

Any help would be deeply appreciated. I am enjoying my dive in the Steinberg world of software, but this has me stumped.

Hi,

Is there any (MIDI) Remote Device involved in your setup?

Martin -

THAT WAS IT! There was a MIDI remote device installed from a StreamDeck template installed in Cubase - disabled it, problem went away.

Thank you!

I don’t see anything listed in Midi Remote Manager. Here’s what I have in Mido port setup. Could it be something here that’s causing the VST to revert to zero?

Hi Greg - see above, it was solved by removing a MIDI remote left over from a Streamdeck profile that was zeroing out the fader on the VST.

Where might I find the curprit Midi remote? It’s not in my Midi port setup.

Hi,

You are right. You are not using MIDI Remote.

Do you use any other Remote Device, like Mackie Control? How are the Quick Control’s Input set? Do you use the given MIDI Port as Quick Controls’s Input, or do you use All MIDI Inputs for the Quick Controls by aby chance?

Well, it took a while, but it turned out to be a controller lane situation. I had created a couple back when I originally recorded and mixed the song. One (or both?) of them zeroed the volume and there it stayed. Eliminating both solved it.

Thanks for your help. Though I’ve used Cubase for a lot of years, there’s still much to know!
