Constant low tone during playback

I created my first project with the default audio settings (with HALion). During playback, a constant low pitch is played on every instrument, in addition to the notes in the score. This makes playback unusable. I’m using a Mac. What could be wrong with my (default) settings?

Could you please post your project here? First rename the file ending from .dorico to .zip, otherwise it will get refused by the bulletin board.

If you don’t want to post it publicly, you could instead send it to u dot stoermer at steinberg dot de

That with the low tone could come from a very low MIDI note that is supposed to be a key switch but now suddenly appears as a regular note.
We would want to have a look at the project file to check this.

It sounds like you must have changed all of the patches in HALion Sonic SE away from the defaults that Dorico is using, but you haven’t told Dorico that you’re using different sounds by changing or unassigning the VST Expression Maps in the Endpoint Setup dialog: click the little cog icon next to the HALion Sonic SE 2 entry in the VST Instruments panel in Play mode and make sure that you choose a benign expression map like “CC7 Dynamics” or whatever instead of the specific HALion Symphonic Orchestra maps it will be using.

Strangly, I was running into the same issue! I hope it doesn’t come back again.

The issue will assuredly come back if you start changing the sounds in your VST instrument (whether it’s HSSE or something else) and that channel is set to use an expression map that expects to use keyswitches that are incompatible with the new sound you’ve chosen. To be clear, if you change the sounds without changing the expression map, you are creating the issue for yourself :smile:
