Ok i try diffrent
I have maudio keystation 61es kb
Now i use with adapter to turn on the kb
I asked if there is a way to use with the usb cable
As a power supply so i would connect my kb to the audya 4 only with one cable(no adapter and no midi)
Because if i connect the kb to the computer its work the same way without midi and without addapter only one cable .
So it is possibale to do that?
Thanks
