General problem with Line-in piano and cut-off sounds

ZOOM Version: 6.3.10 (59437)

Hey,

i connected my piano via USB-midi-controller to my Win 11 PC.

When I play something and record it with the build in Windows Audio recorder, nothing is cut-off, perfect sound.

If I do the same in Zoom, it cuts off lower sounds. It is already done in the microfone test. I already activated "original sounds for musicians" and tried some other settings, nothing helps.

Any ideas?
