ªªAudio Type Page

Audio Type

Soprano Voice

As a result of Antares research into the unique characteristics of various types of audio signals, the TA1VP 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.

ªªAuto-Tune Detune Page

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.

ªªAuto-Tune Sensitivity Page

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 TA1VP 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.

ªªMIDI Channel Page

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.
