I'm not very familiar with the MPC One, but from what i gather is support class compliant USB audio Interfaces on the USB A port.
Thus the MiniFuse can potentially be used to expand the number of audio inputs/outputs on the MPC.
However, the MF can't be used to aggregate its own IO with the MPC IO. That is, you could connect the MPC to the USB A hub on the MF, and the MF by USB C to one of your your computer's USB A ports, but that would only result in the computer seeing the MPC and MF as separate units.
