Yamaha RX21 - Manual (Page 41)

APPLICATION EXAMPLE: 2 RX21’s.
In this example, the left hand RX21 sends MIDI data to the right hand RX21, as
described later in this chapter. Whichever way you wish to send data, the con-
nections should be made as shown.
Clock Modes
The RX21 offers two clock modes (also known as sync modes or synchronization
modes) which function as follows:
1. INTERNAL.
This is the normal RX21 mode. The playback of patterns and songs is synchronized
to the RX21’s own internal clock, the speed of which is adjusted by the TEMPO
control. The internal mode is also used when external sequencers or rhythm ma-
chines are to be synchronized to the RX21’s internal clock, which is transmitted
via the MIDI OUT connector.
2. MIDI.
In this mode the playback of patterns and songs is synchronized to a MIDI clock
signal received from an external sequencer, music computer or another rhythm
machine, via the MIDI IN connector on the RX21 rear panel. In this case the tempo
is controlled by the device which is transmitting the MIDI clock signal.
The desired clock mode is selected by pressing the MIDI button. Normally, the
LCD will read “CLOCK: INTERNAL", indicating that the internal clock mode is
selected. To select the external clock mode, press the +1/YES button. “CLOCK:
MIDI” will appear on the LCD. If you wish to switch back to "CLOCK: INTERNAL",
press the -1/NO button. Once the selection has been made, press any other main
function key to exit. If you turn the RX21 power off, the next time you turn it on
again, the internal clock mode will be selected.
