Fast answer
Choose INT for a TD-3 used on its own. Select the source, not just the clock rate, in the brief sync-edit window.
Try these checks
- Stop the sequencer and press FUNCTION.
- Press BACK + WRITE/NEXT together, then select 1 for INT within about three seconds.
- Let the setting save, reopen the sync edit to check it, then return to normal operation and press START/STOP.
Diagnose it
Is the clock source MIDI, USB or TRIG with no sender attached?
Yes: Select INT for a self-contained playback check.
No: Check that the selected pattern contains notes and timing.
What should happen
A programmed pattern can run from the TD-3’s internal clock.
Why this happens
The quick-start guide requires INT when no external clock is used.
If it still doesn’t work
