Are you also running the latest RealBand 2019 build (build 5)? I don't know if it's related, but look at the second fix below:

Quote:
This patch will update RealBand Version 2019 to Build 5 from any previous 2019 build. It must be installed into your existing RealBand 2019 folder.

Summary of Changes for 2019 Build 5 (Oct 10, 2019)
Fixed: Sometimes the position of the VST/DX plugs window (even if not visible) would prevent a drop, such as into the drop station, from occurring.
Fixed: When batch converting files, the volume of some file types such as wav/mp3/wma/mp4, etc. would be too low.
Fixed: In Chords Window, you could not enter held chords on Piano track.
Fixed: LeadSheet might not display tied notes on the last bar of a track.
Fixed: Pressing "M" key in Editable Notation to insert a new note at the current time location on the Staff was inserting a duplicate note rather than inserting it above an existing note.
If you encounter a problem or have a concern with any of the features/functions of RealBand, do not hesitate to contact us. Updated Oct 10, 2019


I know you aren't batch converting, but are obviously experiencing too low levels.
