Motif-6 > Garage Ban, I want to record my music Options

[Arkenge]

Hi everyone,

I'm new on the forum, and I'm coming as I can't find any explanation on internet (maybe I'm noob )
I've got a Piano Yamaha Motif-6 and iMac with Garage Band.

I'ld like to be abble to record my motif-6 on Garage Band but I can't find any way to do it. No matter what I try, my iMac doesn't seems to receive any sound from the Motif-6.

I've connected the motif-6 to my iMac on their respective USB port.

If someone know what should I do to be abble reccord my-self on my iMac, I'ld be glad.

Thanks in advance for your help.
