Dave Smith Instruments Prophet 12, Operation Manual

Page: 100 / 104

88 Appendix E: Support Dave Smith Instruments
The Prophet 12 plays out of tune.
Check Master Coarse Tune and Master Fine Tune in the Global menu. If that
seems correct, check the pitch wheel calibration on your controller keyboard.
Only voices 7 through 12 make sound; the LEDs for voices 1 through 6 light
up, but those voices are silent.
Make sure the audio cables are not plugged into the B Outputs.
Only voices 1-6 or 7-12 make sound; the LEDs for the non-sounding voices
don’t light up.
You may be in MIDI Multi Mode (Global, 4) and only transmitting on one MIDI
channel.
A filter sounds strange or out of tune.
Run Autotune Filters in the Global menu.
Note:
It is not necessary to run any of the calibration routines on a regular
basis. You should only run it if you are experiencing problems.
Still experiencing a problem with the Prophet 12? Reset Globals in the Global
menu.
Contacting Technical Support
If you are still having a problem with the Prophet 12, contact Technical Support
at support@davesmithinstruments.com. Please include your Prophet 12’s serial
number, the version of the operating system (displayed in the Global screen), and
the purchase date.
Note:
If you have not already reset the Global parameters and run the
calibration routines (see Troubleshooting, above), you should do it before
contacting Technical Support. It’s probably the first thing they’ll ask you to
do.
