lost halion drum set sound after switching audio interface

Dorico
1

Hello,
my project (marimba, vibraphone, drum set) was working fine with my macbook pro built-in audio interface.
When I switched to my external audio interface (Apogee Duet), I lost the drum set sound while the marimba and vibraphone still work fine.
Switching back to the built-in interface does not help, nor “load sounds for unassigned instruments”, “reset playback overrides”, and creating a new drum set.

I am using the Halion Sonic SE 3 with the default [GM 129] Stereo GM Kit and Dorico 2.2. When clicking on the keyboard in the Halion window, I hear drum sounds sounds.
Any idea on how to get my drum set back?
thanks
Florent

Doing Play > Playback Template and choosing ‘HSSE+HSO (Pro)’ and clicking OK doesn’t sort it out?

If not, can you please zip up and attach the project here?
