No!:
ALSA lib pcm_hw.c:1401:(_snd_pcm_hw_open) Invalid value for card
"arecord: main:682: audio open error: No such file or directory"

But my soundcard(disabling the onboard is hw:0 now so I gave:
"arecord -D hw:0 -f cd -f S24_3LE test.wav" but again I got:
arecord: main:682: audio open error: No such file or directory
With "arecord -L' I get:
null

Forgive my ignorance, but shouldn't work with the BOSS GS-10 configuration
(since it's similar chipset with 2 midi ports less?With no midi control I/O)
Anyway ,once again I'm deeply grateful for your help :)
