Set the original microKORG clock source to External for a dedicated MIDI clock source, or Auto when you want it to follow received clock and otherwise use its internal clock. Confirm the master actually sends MIDI clock.
Try these checks
- Open the original microKORG global clock setting.
- Choose External for a dedicated external MIDI clock, or Auto for automatic fallback.
- Connect the master MIDI OUT to the microKORG MIDI IN.
- Start the master and test the arpeggiator.
Diagnose it
Is clock set to External or Auto?
Yes: Check that the sender is transmitting MIDI clock and that the cable direction is correct.
No: Choose the intended external-clock mode and retest.
Is there incoming clock at MIDI IN?
Yes: Check the arpeggiator configuration separately.
No: Enable clock transmission on the master device.
What should happen
The arpeggiator follows the received MIDI clock in External mode, or in Auto when clock is present.
Why this happens
Korg documents Internal, External and Auto clock behavior for the original microKORG.
