Audio Device Error

Hello everybody,
i am newbie here and also
with my mpc one (btw firmware
just updated.
Well, my goal is to connect
my mpc one to my roland mix-1 and
using this one as an audio interface.

I just tried and popped out this:
Error: 44100 may not be supported
sample rate on the external device.
Code: -22

So I will appreciate any help.
Is the any solution?
Groove bless you!

The roland mix-1 is not class compliant, it requires drivers, hence is not supported by the MPC as a usb audio device.
