EFFECTS EDIT MODE: 
In EFX Edit Mode, the EFX Select knob 
is used to navigate through the EFX 
presets. Turning the knob changes 
the EFX preset in the display. The 
new selection will be blinking in the 
display; push the EFX Select knob 
to choose the new effect. Once the 
effect has been selected, you can 
now edit the effect. To do this, press 
the EFX Select knob and the display 
will change to the current parameter 
setting of the preset. Turn the EFX 
Select knob to edit the parameter. 
Press the knob again to exit EFX 
preset edit mode. To restore the EFX 
presets back to factory settings, 
press and hold the EFX Select knob 
for 5 seconds and select "Y" when 
prompted.
AUTO-TUNE EDIT MODE:
In Auto-Tune
®
 Edit Mode the EFX 
Select knob is used to navigate 
through the Auto-Tune presets. 
Turning the knob changes the 
Auto-Tune preset in the display. The 
new selection will be blinking in the 
display; push the EFX Select knob to 
choose the new Auto-Tune preset.
Once the preset has been selected, 
you can edit the preset by pressing 
the EFX Select knob. The display will 
change to the current Key setting. 
Turn the EFX Select knob to change 
the key and push the EFX Select knob 
when you have chosen the key you 
desire. The Key setting determines 
which notes are enabled in the 
Auto-Tune process. For example, in 
the key of CMaj, the notes C, D, E, F, 
G, A, and B are enabled, and all other 
notes are disabled. To see which 
notes are enabled or disabled for 
each key, see the Key Table.
NOTE: If Custom Key is selected, the 
display will enter Custom Key Edit 
Mode. In this mode, you can create 
a custom Auto-Tune Key. Use the 
EFX Select knob to select the Root 
(labeled "RT"). This will be the note 
on which the custom key is based. 
Then use the Media Select knob to 
move the cursor and use the EFX 
Select knob to activate or deactivate 
the 12 notes in the key. Once you 
have finished editing the custom key, 
press the EFX Select knob to exit 
Custom Key Edit Mode. The mixer is 
capable of storing 9 different custom 
keys, one for each preset slot.
The scale degrees are numbered across the 
top, with half-steps indicated by a dash.
"+" indicates the note will be allowed.
"-" indicates the note will not be allowed.
By looking at the sequence of 
allowed and disallowed notes above, 
this is a whole tone scale. There are 
only two of those, so you can have 
the other one just by changing the 
root to C# or B.
*This screen cap shows an A blues scale. You 
don't have to edit the whole scale to change 
keys - just change the root.
Once you have selected the key and 
pressed the EFX Select knob, the 
display will change to the current 
Speed setting. Turn the EFX Select 
knob to change the Speed setting. 
The Speed setting determines 
how quickly and aggressively the 
Auto-Tune will correct the pitch. 
The range for this setting is 0 to 25, 
where 0 is the quickest and 25 is the 
slowest. Push the EFX Select knob 
when you are done editing the speed 
parameter.
The display will now change to 
the current Detune setting. Turn 
the EFX Select knob to change the 
Detune setting. The Detune setting 
determines how the Auto-Tune pitch 
correction is calibrated. When the 
Detune setting is 0 cents, this means 
the Auto-Tune is calibrated to the 
standard A440, or where the note 
A4 equals 440 Hz. The range of the 
Detune setting is -64 to 63 cents, 
a width of 128 cents. The distance 
between two notes, or semitones, 
is 100 cents, which means that the 
Auto-Tune can be detuned to fit any 
possible environment.
NOTE: Detuning the Auto-Tune can 
be very useful, especially when 
being used in conjunction with an 
instrument that is not easily tuned 
on-the-fly. For example, if a piano is 
accompanying Auto-Tuned vocals 
and the piano is slightly out of tune 
from the A440 standard, simply 
change the Detune setting in the 
Auto-Tune setting. This is much 
easier and takes much less time 
than having someone tune the entire 
piano! Also, although the Detune 
setting is changed in the Auto-Tune 
preset edit mode, this is a global 
parameter. This means if you change 
the Detune setting and then later 
change the Auto-Tune preset, the 
Detune setting will not change.
Once you have selected the 
appropriate Detune setting, press 
the EFX Select knob to exit Auto-Tune 
preset edit mode. To restore all 
Auto-Tune presets back to factory 
settings, press and hold the EFX 
Select knob for 5 seconds and select 
"Y" when prompted.
NOTE: Preset 9 is chromatic with 
speed set to 7. It is recommended 
for general purpose, safe, easy 
use of Auto-Tune, without having 
to adjust any settings. The slower 
speed setting does not produce a 
robotic effect on the voice, and all 
twelve semitones are allowed. Just 
remember to use footswitch #2 to 
bypass Auto-Tune between songs, 
otherwise your speaking will be 
Auto-Tuned!
