    MIDI keyboard prologue Connecting the prologue to a computer via MIDI You might want to play the prologue’s keyboard and record your performance on an external MIDI sequencer or computer (connected using the MIDI interface), and then play the prologue while monitoring or playing back what you recorded. You also might want to use the prologue as both an input device for playing notes and as a MIDI tone generator. In either case, you’ll need to connect the MIDI OUT connec- tor to the MIDI IN connector on both the prologue and the external MIDI sequencer or computer. MIDI OUT MIDI IN MIDI interface...

    Owner’s manual. Using the prologue as the master to slave external MIDI devices Connect the MIDI OUT connector of the prologue to the MIDI IN connector on your external MIDI device(s). In the GLOBAL EDIT mode, set the Clock Source of the prologue to “Internal”, and configure the external MIDI device to receive clock data via MIDI. The prologue will act as the master, and the tempo that is set using the TEMPO button on the prologue will be sent as MIDI timing clock data to operate the external MIDI device (sequenc- ers, rhythm machines, and so on).

    Slaving the prologue clock to an external MIDI device Connect the MIDI IN connector of the prologue to the MIDI OUT connector on your external MIDI device. In the GLOBAL EDIT mode, set the Clock Source of the prologue to “Auto (MIDI)”, and configure the external MIDI device to transmit MIDI clock data. The prologue will automatically act as the slave whenever a MIDI timing clock is received, and will be driven by the tempo of the external MIDI device (sequencers, rhythm machines, and so on). Even if you set the Clock Source to “Auto (USB)” or “Auto (MIDI)”, the prologue will operate in “Internal” MIDI clock mode, unless a clock is re- ceived from an external device.
