Troubleshooting
If you find the DR-670 is not operating correctly, check the items listed below.
If the DR-670 still does not work properly after you check these points, consult your local Roland
Service or your dealer.
No Sound
❏
Is the volume turned down (p. 18)?
❏
Is the output part set to “DRUM” or “BASS”
(p. 76)?
❏
Is the instrument’s level set to “0” (p. 80)?
❏
Have you selected a pattern or song
containing no performance data?
Sounds Drop Out
❏
Are you playing too many sounds
simultaneously?
The DR-670 has a maximum polyphony of
20 sounds (voices). Some instruments use
two voices each time they are played, so
using such instruments results in reducing
polyphony to fewer than 20 voices.
With some kinds of patterns, you can reduce
the number of voices that sound
simultaneously by setting the Assign Type
to MONO. This would be effective, for
example, in a pattern where a lengthy
cymbal sound is triggered on every beat.
❏
Could there be a mistake in the Assign Type
settings (p. 82)?
Can’t Play Rolls/Flams
❏
Could there be a mistake in the Flam
Interval or Flam Ratio settings (p. 78)?
❏
Are you trying to play a roll or flam with a
bass part?
