Set the clock entry to Ext in MIDI → FiLt and save with WRITE. If both USB and DIN supply clock, the manual gives USB priority.
Try these checks
- Hold SHIFT and press PROGRAM MEMORY 4 (MIDI).
- Select FiLt with PROGRAM/BPM, press the knob, then open the clock entry and choose Ext. Press WRITE.
- Send clock through the intended input. If testing DIN timing, stop an unwanted USB clock source.
Diagnose it
Are both DIN and USB supplying clock?
Yes: USB takes priority in Ext mode; stop the unwanted sender.
No: Check Ext selection and the sender’s clock output.
What should happen
The PRO+ follows the selected external timing, with the documented USB priority.
Why this happens
The clock filter chooses timing separately from connecting a cable.
If it still doesn’t work
