HSO missing instruments

I’m sure this topic has been covered somewhere but can anyone direct me to the solution (for Cubase Artist 10).

In a HalionSonic Track I can load HSO as an instrument, and have access to all the instruments within it.

In a track of HSO alone, I dont have access to any but the default instrument and no other i.e. not visible in popup and not available by < | > selection.
Are there different locations for the associated sound files / presets for instruments? Should there be shortcuts to the folders where the instruments are, in more than one place?

I have vstsound files on C and D drives (MSWindows 10) and Library Manager shows these correctly placed, and reports no problems.

many thanks,


The HSO plug-in itself is not supported anymore. Use HALion Sonic SE as a player, please.
