(+1 or –1) signal levels. These levels represent the “rails” 
of the amplifier. As the Warmth Amount is increased, 
the amplification is increased. Any regions of the signal 
that increases beyond the rails generate distortion. 
(But instead of the usual ugly digital clipping, they are 
distorted the same way the tube pre-amp would distort 
the sound.)
Because the maximum drive is limited to +12 dB, using 
the Tube Saturation model requires the original signal to 
be at a level greater than –12 dB. If this is not the case, you 
should adjust the Input analog Trim control (in the Setup 
Menu) to increase the level of the sound. (Be careful that 
Input Level is not increased so much as to cause digital 
distortion.) It may be necessary to go back and forth 
between Warmth Amount and Input Trim a few times to 
get exactly the effect you want.
NOTE
If your audio was recorded at an exceptionally low level, 
it may be that even maximum Input Trim and maximum 
Warmth Amount will still not result in a level high enough 
to generate distortion. In that case, either re-record your 
audio at a higher level (if possible) or use an available 
digital waveform editor to digitally increase the level 
(keeping in mind that this may negatively affect the signal 
quality).
If you want to add tube warmth without otherwise 
affecting your sound, set both the Source Mic and 
Modeled Mic to Bypass.
MIC MODELER ON Button
 
ª
When this button is lit, the MIC MODELER module is 
active. When it is not lit, the module is bypassed. Pressing 
the button toggles its state. The Mic Modeler On/Off 
function can also be controlled by MIDI and/or by a 
footswitch.
AUTO-TUNE MODULE 
Scale Page
 
ª
Pressing the SCALE button brings up this page.
You tell Auto-Tune exactly which notes you want to 
correct on the Scale Page:
Ch:CC#DD#EFF#GG#AA#B
  :
This page allows you to specify the scale notes to which 
Auto-Tune tunes the input sound.
The TA-1VP comes with 25 preset scales: Chromatic, 12 
diatonic major and 12 diatonic minor. To select a preset 
scale, use the cursor buttons to move to the scale name 
field in the top left of the screen and turn the Data Knob 
to select the desired scale. Note that "
Ch
" is short for 
"Chromatic", the scale with all 12 notes.
In addition, you can customize any of the provided scales 
and save it as part of your preset. To modify a scale, press 
the Á cursor button to move the cursor to the bottom 
row of this screen, then use the cursor buttons to move to 
the desired scale note and turn the Data Knob to set it to 
one of the following three states:
Tune (i.e., the note name appears in the display, but 
the field under the note is blank): When the input is 
near a note set to Tune, Auto-Tune will retune the 
input to that note.
Bypass (i.e., the note name appears in the display and 
an “
*
” appears in the field under the note): When the 
input pitch is close to a note set to Bypass, the output 
remains uncorrected.
Blank (i.e., the note name disappears from the 
display): A note set to Blank will be omitted from the 
scale. For example, setting C#, D#, F#, G#, A# to Blank 
causes a C Major scale to remain. In that case Auto- 
Tune would always retune the input to the closest 
note of the C Major scale.
As an example, the following settings result in a D Major 
scale with no pitch corrections applied to F# and C#:
D : C#D E F#G A B
Ma:  *     *
Why set Scale notes to “Blank”?
To understand why it is sometimes necessary to set 
even correct scale notes to ”Blank,“ let’s look again at the 
example from Chapter 2.

This phrase is in D Major and, if all the pitch errors were 
no greater than about 49 cents, would work fine with a 
standard D Major scale (D, E, F# , G, A, B, C# ). However, the 
pitch error of three semitones at the end of the last note 
is so large that with B and C# present in the Scale, as the 
pitch fell, Auto-Tune would see first C# and then B as the 
target pitch and therefore allow the error to remain. With 
C# and B removed from the Scale, Auto-Tune continues 
to see D as the target pitch for the entire duration of the
