Accept External Clock Value; Send Clock Value To Other Devices - Akai XR 20 Reference Manual

Page 5 / ACCEPT EXTERNAL CLOCK VALUE (CLOCK IN)
Playback and tempo on the XR20 can be controlled by external devices through MIDI Clock if:
The external device (sequencer, drum machine, etc.) generates MIDI timing signals.
These signals go from the external device's MIDI OUT to the XR20's MIDI IN.
CLOCK IN is ON.
To have the XR20 recognize clock (timing) messages
present at its MIDI input, use the INC/DEC buttons or
VALUE dial to select ON (if no clock messages are
present, the XR20 will follow its internal clock tempo).
Select OFF to have the XR20 ignore clock messages
and follow its internal clock tempo regardless of what
timing data appears at the MIDI IN.
Tip: When using the XR20 as an expander module, set CLOCK IN to OFF so that
timing signals don't start playing a Pattern.
Page 6 / SEND CLOCK VALUE TO OTHER DEVICES (CLOCKOUT)
The XR20 can generate MIDI Clock timing signals to which other devices can synchronize if:
The external device (sequencer, drum machine, etc.) can respond to MIDI timing signals.
These signals go from the XR20's MIDI OUT to the external device's MIDI IN.
CLOCKOUT is ON.
To have the XR20 generate timing data at its MIDI out,
use the INC/DEC buttons or the VALUE dial to select
ON.
Select OFF to inhibit MIDI timing signals from appearing
at the MIDI out jack.
Tip: When slaving the XR20 to other devices,
CLOCKOUT should be OFF and CLOCK IN
should be ON.
