7.4 MIDI Clock In
An external clock can be used from a connected MIDI input. The external
device which is the clock primary lead must be set to send the clock
messages across the MIDI connection.
▌ USING AN EXTERNAL MIDI CLOCK
1. Use a 5-Pin MIDI Cable to connect the MIDI Out, or MIDI Thru to the
Pulsar-23 MIDI In socket.
2. Ensure the external device settings allow transmission of MIDI and is
set as the primary lead to send its clock. This will differ between devices
so follow the manufacturers instruction for configuration of the device.
3. Set the ‘INT MIDI’ Switch located in the master clock module to the left,
{MIDI} position. This sets Pulsar-23 to use the clock received from the
MIDI in device.
4. Remember several points of note when using an external MIDI clock:-
• The looper recorder and clock dividers will reference the incoming
MIDI clock instead of the internal clock.
• The looper recorder has an upsampled clock speed and as such
needs settling time after the clock starts. The time between an
incoming start and stop of the sequencer should be longer than 5
seconds to allow for stabilisation between clock and looper recorder.
• To avoid settling time issues with the looper recorder, patch the
‘LRST’ Pin to the ‘0.25’ Pin of the clock dividers. This will retain a
good synchronisation with the looper recorder.
• The ‘CLK’ pin in the master clock module can be used to patch a
clock from the internal or external clock signals. Patched to an
external module like Pam’s New Workout will give a visual BPM
display of the clock tempo.
