* Although Roland has tested numerous configurations, and has determined that on average, a computer system similar to that described above will permit normal operation of the Rubix, Roland cannot guarantee that a given computer can be used satisfactorily with the Rubix based solely on the fact that it meets the above requirements. This is because there are too many other variables that may influence the processing environment, including differences in motherboard design and the particular combination of other devices involved.
