Fast answer
Raise the selected step's velocity, as Moog advises for external triggering that produces no sound.
Try these checks
- Confirm that the DFAM can produce sound when its own sequence runs.
- Check which step is selected and raise that step's velocity.
- Retry the external trigger. If it remains silent, check the controller's own output documentation before changing the patch.
Diagnose it
Does the internal sequence play but external triggering stay silent?
Yes: Check the selected step's velocity first.
No: Check the DFAM's sound setup before assuming a trigger-input fault.
What should happen
Raising the selected-step velocity removes the documented velocity-related cause of silence.
Why this happens
The external-trigger troubleshooting article points to the selected step's velocity.
If it still doesn’t work
Check the connections and settings described above. If your device behaves differently, email us with its model, firmware version and the steps you tried.
