Audio Type Page ª
Audio Type
Soprano Voice
As a result of Antares research into the unique
characteristics of various types of audio signals, the
TA-1VP Auto-Tune module offers a selection of optimized
processing algorithms for the most commonly pitch-
corrected inputs. Choices include Soprano Voice (default
setting), Alto/Tenor Voice, Low Male Voice, and Instrument.
Matching the appropriate algorithm to the input results
in even faster and more accurate pitch detection and
correction. Use the Data Knob to select the desired Input
Type.
NOTE
Best results are obtained when the Input Type setting
selected here matches the actual audio signal you are
providing to the TA-1VP.
Auto-Tune Detune Page ª
Auto-Tune Detune
0 cents
The Detune parameter allows you to change the pitch
standard of the TA-1VP’s Auto-tune module from the
default A = 440 Hz. The values are cents (100 cents = a
semitone). The range of adjustment is from –100 to +100
cents. (The default setting is 0 cents)
The Detune function can be used to tune a vocal
performance to some irreparably out-of-tune instrument
(a piano or organ, for example), or to allow correction to
other than the conventional 440 Hz standard.
Refer to the following table to convert cents to Hertz
relative to 440 Hz.
DETUNE SETTING A=HERTZ
–20 435
–16 436
–12 437
–8 438
–4 439
0 440
+4 441
+8 442
+12 443
+16 444
+20 445
This table can be extended in either direction by adding
or subtracting 4 cents per Hertz, as appropriate.
Auto-Tune Sensitivity Page ª
Auto-Tune
Sensitivity: 10
The Sensitivity parameter ranges from 0 to 25 (default
setting is 7) and controls how the TA-1VP extracts the
input signal's pitch from any accompanying noise.
In order to accurately identify the pitch of the input,
the TA-1VP’s Auto-Tune module requires a periodically
repeating waveform, characteristic of a voice or solo
instrument. The Sensitivity control determines how much
variation is allowed in the incoming waveform for the
TA-1VP to still consider it periodic.
If you are working with a well-isolated solo signal (e.g.,
tracking in a studio or off of a multi-track tape) you can
typically set the Sensitivity control to 10 and forget it.
If, on the other hand, your signal is noisy or not well-
isolated (as might be more common in a live performance
situation), it may be necessary to allow more signal
variation (higher Sensitivity numbers). However, if you
back off too much, the TA-1VP’s ability to detect pitch may
be affected.
As a rule, you should start with settings of about 7 to 10. If
you want to detect only highly stable sounds in low-noise
conditions, settings of from 2 to 5 may be appropriate.
If there is ambient noise or other interfering sounds, try
settings of from 15 to 20. Values close to zero or 25 are
extreme, and will typically not do anything useful.
MIDI Channel Page ª
MIDI Channel: OMNI
MIDI Prog Change: ON
The MIDI Channel parameter selects the channel over
which the TA-1VP receives MIDI continuous controller and
Program Change messages. The choices include:
Individual MIDI channels 1–16 If an individual
channel is selected, the TA-1VP will respond to
messages received on that channel only and will
ignore any messages on other channels.
OMNI (default setting) If OMNI is selected, the TA-
1VP will respond to messages on any MIDI channel.
When MIDI Program Change is set to ON, the TA-1VP will
respond to MIDI Program Change messages received on
the selected MIDI channel. When it is set to OFF (default
setting), all MIDI Program Change messages will be
ignored.
