Oberheim Matrix-12 - Page 48

PW, insures the uniformity of the final VCA of each Voice. This calibration
makes the volume level of each of the 12 Voices equal.
• To tune an individual parameter, press the button directly below its
name in the display. If RES is selected, VCF is also selected
automatically. This is because the reliability of the VCF tuning is
dependent upon the scaling of the Resonance parameter. It is
logical, then, to tune them together if RES is selected.
• To tune all of the parameters, press ALL. The MATRIX-12 will
proceed through its entire Auto-Tune cycle, which takes about 90
seconds to complete.
1. During the Auto-Tune routine, the message" TUNING" will appear on
the LOWER display directly beneath the parameter being tuned. When
the MATRIX-12's processor is finished all 12 Voices for a given
parameter, the message "PASS "will appear on the LOWER display
directly beneath its name.

If, for any reason, the MATRIX-12 cannot successfully tune all 12
Voices for one of the parameters, the mesage "FAIL" will be displayed
in the LOWER window directly beneath the parameter's name.
Pressing PAGE 2 will display the Voices that failed for that parameter.
The first Voice out of the 12 to fail is displayed and turning the knob
directly beneath that parameter will display the other Voices (if any) that
have failed.
Failed Voices is a rare occurance and may happen if the MATRIX-12 is
used in an environment that has extremes in temperature and/or
humidity. You may also experience some Voice failing on occasion if
the MATRIX-12 is tuned immediately after you first power it on, due to
the fact that the synthesizer requires approximately 30 minutes of
warm-up time in order to temperature-stabilize. If you get consistent
Voice failing after several Auto-Tune attempts, your MATRIX-12 may
need servicing. Consult the Oberheim Authorized Service Center
directory included in your Owner's Packet.
After a successful Auto-Tune, pressing TUNE PAGE returns the front
panel back to its original displays.
