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 MC-909 Editor, Roland cannot guarantee that a given computer can be used satisfactorily with the MC-909 Editor 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. (How to Install) Download and run MC909Editor100.EXE, and double-click Setup.exe. (Note) A separate MIDI interface is required in order to connect the MC-909 with the computer. Using MIDI cables, connect both the MIDI IN and MIDI OUT connectors on the MIDI interface connected to your computer to the MIDI connectors on the MC-909.
