## What is Vocal Soloist AUv3 Plugin?

This is an AUv3 compatible effect plugin which is intended for use inside your favourite DAW such as Cubasis, Auria, Meteor, AUM or GarageBand etc. 

The Vocal Soloist plugin was specifically designed for adding harmonies and basic auto tuning frunctionality to recorded vocal lines. It is specifically tuned to the frequency range of the human voice and tracks the incoming vocal frequency attempting to tune to the desired musical key and mode of your song.

This effect works in real-time and is able to track a monophonic input creating a convincing harmony at either a specified number of semitones or a key/scale offset. The auto tune allows you to snap to the nearest semitone in chromatic mode, or scale note when a key / mode is selected.

We have also included our very popular vocal doubler and reverb to give added presence and thickness to your vocal lines.

The effect includes MIDI control over pitch. If your DAW (such as AUM) supports sending key on/off information to the effect you can directly control the pitch of the harmony. For those DAW's that do not support this you are able to route MIDI from one instance of Vocal Soloist to another instance listening on the same bus. 

The effect also includes controls for defining your own scales as well as controlling vibrato.

Features:

○ Real-time processing.
○ Allows fixed 3rd, 5th, 7th harmonies etc.
○ Basic Auto-tune (snap to nearest note).
○ Specify a musical key and mode.
○ Ability to snap harmonies to selected key.
○ Built in Vocal Doubler.
○ Built in Reverb Effect.
○ MIDI control for harmony note.
○ Built in MIDI routing.

Note: You can now load this plugin using the internal name 'SoloistFX' or 'HarmonizerFX'.

### 1/5 — Une catastrophe

*2025-02-23*

Une catastrophe les pistes vocals se déplacent, l’autotune ne marche pas a fuir

### 2/5 — Does what it says but…

*2024-11-30*

This app has no formant control so harmonies sound unnatural. Beware before buying.

### 2/5 — I don’t understand the point

*2024-10-29*

The sound is very over processed, it doesn’t seem you can use just auto tune function alone.

### 1/5 — leider zu hohe Latenz ..

*2024-01-08*

.. selbst auf einem M1 IPad …

### 1/5 — Not worthy for money

*2023-12-14*

Not worth for money you can use another plugin

### 1/5 — App works but not feasible for live

*2023-10-27*

It would be completely awesome if this could replace using a harmonizer box on stage…but the only place else I found unusable latency was with Bluetooth MIDI. Where it could work would be if you sang a very slow song…the features aren’t as good as a $200 tc-helicon box…but I could see a future where this kind of thing would be used

### 1/5 — Wont work

*2023-07-22*

It crashes on Logic Pro (iPad) not happy

### 3/5 — Cool but crashes

*2023-05-29, version 1.09*

Cool but crashes in Logic Pro

### 1/5 — Another one that doesn’t work.

*2023-05-24*

If you’ve got the latest IOS this won’t work.

### 3/5 — Pretty high latency on ipad pro 2018

*2023-03-18*

Not usable as a live effect as it has a damn high latency
