Imagine a plug-in that allows you to tune your vocal recordings, apply special effects and add natural sounding harmonies when mixing your track. Look no further, Mu Voice is the plug-in for you. The proprietary spectral analysis and synthesis techniques of Mu Technologies set a standard in vocal processing providing a unique tool for your recording studio. An internal delay of only 5.8 ms makes Mu Voice the ideal vocal processor to perform live on stage.

Intelligent Harmonizing

An "intelligent" harmonizer takes into account the musical context of a piece like chord and scale information. This is exactly what Mu Voice does. A four track mixer allows to configure the voicing (1st, 2nd, 3rd or 4th voice) and octave for each channel.

Scale / Chord Selection

The chord panel offers a straight-forward interface to select chords. When a given key signature is selected, the diatonic series of chords is displayed. By clicking the chords and modifiers, a chord is selected for harmonization.

Chord Scheme Editing

Chords can be added to a scheme by pressing the "Insert" button or double clicking them. By clicking an item in the scheme one can navigate through a chord scheme.

Mixer

The mixer combines all four track and allows to mute certain channels with the [M]-button. The first channel can be put in bypass ([B]-button). A pitch shift slider adds an extra interval to the channel. The range of the shift slider is expressed in half tones can be quantized by pressing the [Q]-button.

Tuner

Mu Voice comes with a built-in tuner that has a parametric impact (0: no impact, 1: full impact). The tuner has two modes:

• "Chromatic": tune to the closest half note
• "Scale": tune to the closest note in the current scale

Channel FX

In addition to the voicing configurator, the gain control and pitch shifter, each track has additional set of FX

• Pan: To abtain a realistic spatial positioning, the panner uses interaural delays and an interaural gains that are based on psychoacoutic measurements. The panning parameter corresponds with the angle relative to the listeners nose.
• Humanizing: When the pitches of the harmonies are coupled too tight, they might interfere and be perceived as a single distorted voice. The "humanization" parameter solves this problem by adding very slight random pitch variations and an additional delay.
• Formants: The formants determine the "timbre" or "color" of the voice. When the pitch of the Voice is altered, the formants are maintained. One can disable the formant correction by pressing the green button next to the slider. The formant slider controls a linear scaling of the formants and alters the colour of the voice. By shifting the pitch up and scaling the formants, the voice of a women can be changed to the voice of a young girl.
• Filters: Mu Voice offers a number of filter presets; high-pass, band-pass, comb-filters, notch filters ...
• Harmonic EQ-ing: The proprietary spectral analysis technique on which Mu Voice is based, allow to control the amplitude of each harmonic in the sound. We named this effect harmonic EQ-ing. A number of presets are provided that illustrate this unique feature.

Full Automation

The progression of chords and presets can be fully automated in two steps

1. Write Mode: The plug-in is put in read-mode by pressing the [W]-button above the chord scheme. When you select a starting point and press the right arrow on your keyboard, you will move to the next position is the scheme while the timing of this event is recorded.
2. Read Mode: The plug-in is put in read-mode by pressing the [R]-button above the chord scheme. The plug-in will synchronize itself to the host time so that it becomes fully automated.

XML based file exchange: The plug-in state, chord scheme and presets can all be saved in XML. This makes the configuration of your plug-in readable, editable and portable over all platforms.

SIMD Optimizations

Mu Voice is highly optimized exploiting special processor instruction sets like SSE for Intel processors and Altivec for PowerPC's.

• All audio must be sampled at 44100Hz.
• Mu Voice uses two data files, W.dat and Y.dat. When it can't find them is generates them automatically. Therefore, when you launch the plug-in for the first time it will take a while to appear. From there on it will launch smoothly.
• Mu Voice works strictly for monophonic audio material.

Mu Voice 1.1.2 Update

The main change in version 1.1.2 is that we now support a wide range of sample rates:
44.1 kHz - 48 kHz - 88.2 kHz - 96 kHz - 176.4 kHz - 192 kHz

Mu Voice 1.2.0 Update

At last! The MIDI-enabled version of Mu Voice, version 1.2.0 is now available. This version gives you full control over Mu Voice from a MIDI keyboard, making it an excellent tool to perform live in a real-time host like Ableton Live, Apple MainStage, and more. Features:

1. key selection
2. chord recognition
3. preset selection
4. chord scheme navigation
5. configurable for any type of keyboard from 24 to 88 keys.

Mu Voice 1.3 Update

• Drag-and-drop: Now you can just drop your XML files on the plug and it will load them.
• PlayList Configuration: Allows you to create a list of XML files for different songs.
• Advanced MIDI Mapping: MIDI support is extensively elaborated. In 1.2 the plug-in could be controlled with MIDI note events. This is now extended to Program changes and MIDI Controls. You can map any MIDI controller to any set of parameters and define a mapping curve for each individual parameter. Want to shift the pitch of one channel up and another channel down when pressing a foot pedal? Want to go from one to three voices when turning a controller knob? It all can be done.
• Chord Scheme Anchors: The chord scheme is extended with anchor points. For instance, you can create anchor points for the beginning of each verse and chorus and use them to jump back and forth to the next verse or chorus.
• MIDI Navigation Controls: A set of navigation controls is provided to go to the next chord scheme position, anchor point and XML file. Each control has a MIDI learn function to which you can assign a specific event.
