# KeroVee ver 1.61 (c) g200kg 2010-2013
## Overview
KeroVee is a PitchCorrection plugin that works as a VST effect.
KeroVee should be used with VST compatible host application (ex, Cubase).
KeroVee can mix two independent transposed outputs of pitch-corrector and bypassed output.
## How to Install&Use
Just place KeroVee.dll to your plugins directry.
Insert KeroVee to audio track (Note that the audio track should be 'stereo' if
you want to use panning).
Root the MIDI signals to KeroVee if you want to use the 'TuneTo MIDI' function.
KeroVee need SSE2 ready CPU (ver 1.60)
## Params
* Scale Buttons 'C'to'B'
Specify the 'Allowed' note.
Also the Scale-Setting menu is available that will set Scale buttons as a whole.
* TuneSpeed
Tuning Speed. Maybe robotic if set to max.
* Nuance
Keep or ignore subtle pitch changes like vibrato
...added in ver 1.60. same as earlier version if set to max.
* Amount
Pitch correction amount. just to the correct pitch when set to max.
* Calib
Master tuning from 430Hz to 450Hz. the default is 440Hz
* TuneTo
- Scale -- Enable Tuning to specified scales by scale buttons
- MIDI -- Enable Tuning to Midi notes.
MIDI notes are processed as monophonic.
Last MIDI note is effective.
Octave is NOT ignored.
- MIDI Chord -- If this switch is on, multiple allowable notes can be specified by MIDI notes.
Octave is ignored.
- If both of Scale and MIDI is enabled, the MIDI note is prior. but scale tuning is effective after notes are offed.
- If not enabled both, the output pitch is follow to the input pitch, but be tweaked with transpose and formant parameters.
* Bypass - Level - Pan
Bypassed output of source sounds.
* Tone1 - Level - Pan - Transpose - Fine - Shift - Presv
Pitch-corrector output.
- Level: output level
- Pan: output pan (Note that the audio track should be stereo)
- Transpose: transpose output pitch
- Fine: fine tuning of the output pitch
- Shift: formant shift.
- Presv: formant shift mode.
On: formant is preserved. independent to the pitch correction. formant shift is still effective in this mode.
Off: formant is changed depend to output pitch.
* Tone2 - Level - Pan - Transpose - Fine - Shift - Presv
One more Pitch-corrector output same as Tone1.
* MasterVol
Master volume.
