A NDROMEDA A6 R EFERENCE M ANUAL 267
The TUNEOK in the Oscillator columns means that the first six bands (which represent
the lower octaves of the range) of this voice (12, in this case) went through an Auto
Tune process and were OK. The
NOTUNE in the Oscillator Pulse Width column
shows that the Pulse Width has not gone through an Auto Tune process. The TOOHI
in the 5 th band of Filter 2 shows that Auto Tune was not able to bring this band into
range. (Unless you're using Filter 2 as an oscillator, and playing it in the highest
octaves, this won't be noticable.)
It isn't unusual for the very highest bands of the oscillators to be out-of-range after an
Auto Tune procedure, especially if the unit is cold. Try again after the unit has
warmed up. Even when the tuning is not exact enough to "win" an "OK" from the
computer, it may still sound OK. But if a voice won't show "OK" in its lower bands,
after several attempts, the unit may require servicing.
T O CHECK FOR AN OUT - OF - TUNE VOICE :
1. Press AUTO TUNE once.
2. Turn the VOICE knob (soft knob 7 ) to show Voice 1 in the display.
3. Note any voice bands that do NOT say TUNEOK .
4. Turn the BAND knob (soft knob 8 ) to show band 7 at the top of the display.
5. Again, note any voices that say TOOHI or TOOLO .
6. Turn the BAND knob (soft knob 8 ) to show band 13 at the top of the display.
7. Again, note any voices that say TOOHI or TOOLO .
8. Turn the VOICE knob (soft knob 7 ) to show the next voice in the display, and
repeat steps 3–8 until all bands of all sixteen voices are checked.
If a band isn't in tune, let the instrument warm up for a while, and perform a
complete Auto Tune again before proceeding to the next step.
T O TURN OFF AN UNTUNED VOICE :
If the Auto Tune procedure doesn't fix a voice and it's noticeably out of tune, there
may be a physical problem with the instrument. In this case, Auto Tune will
automatically turn the voice off. All other voices may be in tune… it's only when this
untuned voice is called on that you could hear a pitch problem. But the Andromeda
does allow you to turn off individual voices using its Voice Monitor feature. You'll
lose a voice of polyphony, but the voices that remain will be in tune.
After you know which voice can't be tuned using the procedure above:
1. Press GLOBAL .
2. Press VOXMON (soft button 8 ).
3. To turn a voice off, press any of the SELECT buttons ( 1/9 through 8/16 ). Press SHIFT
to access voices 9–16.
Another way to check quickly for "problem" voices is to watch the VOXMON display
while playing. An "X" appears above the voice number as it's played. When you
hear the voice that's out of tune, note which voice has an "X" above it.
