MIDI Clock Sync
The HeadRush Looperboard can be synced to the tempo of an external MIDI device (e.g., a drum
machine) while recording and playing your loops in Fixed, Sync and Serial-Sync modes.
The HeadRush Looperboard can receive MIDI clock from a device connected to the traditional 5-pin
MIDI Input, or from a class compliant device connected to the USB Type-A Ports on the rear panel.
You can enable or disable the MIDI Clock Sync feature, as well as set the MIDI Clock Source, in the
Global Settings menu.
Tips:
• Tempo cannot be changed during recording, so make sure the HeadRush Looperboard is
accurately receiving the MIDI clock before beginning.
• Receiving MIDI Clock Sync works best when using properly cut loops. Loops that are miscut or
have odd or uncommon bar lengths may not work properly or cause unexpected results.
When MIDI Clock Sync is enabled:
• Looper tracks can be armed for recording or overdubbing by pressing their respective
•Rec/Play/Dub footswitches. The LEDs for these footswitches will flash when the track has
been armed and is ready for recording or overdubbing.
o If the external MIDI device’s clock is not running yet, and the looper track mode is set to
Fixed, tracks will begin recording or overdubbing when a MIDI Start command is
received.
o If the external MIDI device’s clock is already running, and the looper track mode is set to
Fixed, tracks will wait to begin recording or overdubbing until the next downbeat.
o If the external MIDI device's clock is already running, and the looper track mode is set to
Sync or Serial-Sync, tracks will wait for the master track to return to the beginning to
begin recording or overdubbing.
• HeadRush Looperboard will stop recording or overdubbing once a MIDI Stop command is
received from the external MIDI device.
• If the external MIDI device's clock is running, looper track playback can be started and stopped
using the •Stop/–Undo footswitch.
o In Fixed mode, tracks will stop immediately after pressing the •Stop/–Undo footswitch.
o In Sync or Serial-Sync mode, tracks will stop when the end of the master track is
reached.
• If the external MIDI device's clock is not running, looper track playback cannot be started and
stopped using the •Stop/–Undo footswitch.
• The loop’s tempo cannot be manually changed.
• The Sync Audio to Tempo feature in Global Settings cannot be disabled.
• The Start/Stop All and After Record features in Global Settings will not be applied.
