BoosterMusicBooks midi files are not playing on my keyboard

Piano Booster Version 1.0.0
Yamaha P-150
Windows 11
MIDI to USB cable

Hi,

I have Yamaha P-150 and use a headset.

"Third-party" MIDI files are normally played through the keyboard/headset and I can follow them.

However BoosterMusicBooks files are not though I can follow them as well. If I change Midi output to Internal sound (FluidSynth) I get the sound.

Midi diagnostic apps showed all works fine.

Any ideas?

Thank you!
