No Preview Sound in Media Bay in Elements

I use Cubase Elements. Just upgraded from 11 to 12. There’s no sound through the previewer in the Media Bay. There used to be in 11, but after the upgrade, neither gives a preview sound in that window. (If I click the small keyboard it gives the sound of the current Record Enabled track, not the previewed instrument.)

There’s no Control Room setting in Elements, I believe. In Audio Connections, there’s tabs only for Inputs and Outputs.

I have tried right-clicking Stereo Out and ticking Set “Stereo Out” as Main Mix (it’s active).

I have also tried running v. 12 with the settings disabled.

Hi and welcome to the forum,

Could you try to disable and re-enable this, please?

Also make sure the Preview Volume is not set to -oo, please.

Thanks for helping me out!

I only have one bus, Stereo Out. If I create another (let’s call it “Test Bus”), I can switch Set “X” as Main Mix. I have tried toggling on both. If I restart “Test Bus” is deleted and the “Stereo Out” is resetted.

There’s sound from the track instrument when I click the small keyboard in the Media Bay but not the previewed one. If I click the Play button to play a MIDI file in the previewer no sound is heard.

Playing with the preview volume doesn’t make a difference.


Then I wouldn’t search for the solution in the routing. To me or sounds like the MIDI loop is not available.

I noticed that previewing sounds in the MediaBay work with Groove Agent and some other VST instruments, but not HALion Sonic.

It worked in v. 11 before I installed 12.

I don’t think I’m going to continue to find a solution to this issue, I’ve tried so many things. Like removing the libraries manually and then reinstalling them.

But it’s not a big deal as you can quickly try the VSTs by double-clicking and playing them from the tracks.

In my opinion, the previewing of different instruments is one of the best features of Cubase. It certainly was one of the biggest reasons I went with it.


Make sure, you have the latest HALion Sonic (SE) 7 (including the library) installed, please.

I experience the same problem with CB12 Pro and Halion 6. After I installed Halion Sonic 7 (7.0.10) the preview of sounds in the Mediabay does not work anymore for presets with the plugin name ‘Halion Sonic SE’. For all other plugins this works fine.

After deinstalling Halion Sonic 7 the preview of sounds works fine again. Tried to find a solution by reinstalling CB12 Pro, Halion 6, Halion 6 content, … but without succes.
I would like to use the new Halion Sonic 7, but the preview funtion is important to me. Do I have to wait for a fix, or is there a solution to repair the preview function?
Any help is appreciated.

In the Steinberg Download Assistant I have installed:
HALion Sonic 7.0.10 - Instrument
HALion Sonic SE 3 - Content

(I haven’t installed the “optional” packages as I don’t want them.)

In Steinberg Library Manager, under the HALION tab, these are listed:
HALion Sonic Factory Content
HALion Sonic SE Common Presets Content
HALion Sonic SE Content
HALion Sonic SE Trip

This doesn’t sound like HALion Sonic SE to me. It sounds more like HALion Sonic, where you need a license for.

Halion does not preview its sounds you have to double click as you say you are doing. There is a work around with this but I can’t recall what it was. It is a small loss of time to have and slightly irritating to have to load every sound to hear it but bearable…
