GarageBand : cracked sound recording with audio interface ARTURIA MINIFUSE 1

I am trying almost one month to solve the following problem:

SET UP: CASIO CT-X800 OUTPUT-->1/4" TRS to 1/4" TS (cable)-->LINE INPUT OF MINIFUSE1-->Computer Output of MINIFUSE1-->USBC to USBC (cable)--> MACBOOK PRO-->GARAGEBAND 10.4.12, Create New Track, Mic or Lilne Audio INPUT. (Hopefully the cable 1/4"TRS tp 1/4" TS, Stereo to Mono, is correctly made up! I used other cables as well but in vane)

MINIFUSE 1 setup: LINE input selected (input light OFF), 24 bit, 44,1 KHz Sample Rate (hopefully it is automatically selected by GarageBand!). MINIFUSE1 covers Sample rates from 44.1 KHz to 192 KHz.

The payback sound of the piano recorded track is totally cracked, NOT CLIPPED, i.e. sounds like tak, tak are heard every 1 or 2 seconds. I tied many combinations of volumes...

Using the same setup, but using WAVEPAD or QUICKTIME PAYER programs, the recorded piano sound is crystal clear!

Any idea what could be the cause?

I need urgent help before I get crazy!... Really... All consultations for the time being failed 😒

Thank you very much in advance.
