KeroVee 1.61

Pitch Corrector/Autotune Effect.

Overview

KeroVee is a PitchCorrection plugin that works as a VST effect. You need to use KeroVee.dll with your VST compatible host application.

KeroVee is focused to so-called 'Autotune effect' or 'T-Pain effect', that is robotic but different from the vocoder. 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.
  • Route the MIDI signal to KeroVee if you want to use the 'TuneTo MIDI' function.

HowTo Use (KeroVee 1.24)



KeroVee 1.53

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 Correction amount. Just to the correct pitch when set to max.
Calib Master tuning 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 must 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.

History

ver 1.61 2013/04/06 - Fix squealing when low freq noise input.
ver 1.60 2013/04/02 - Improved noise suppression
- Nuance parameter is added
- Optimized to SSE2. CPU consumption is improved.
ver 1.53 2011/08/08BugFix: not reporting exact latency value to Host.
Reduced latency for live performance.
Improved GUI performance especially when opening GUI.
ver 1.52 2011/07/10BugFix: Cannot work on SSE1 only supported CPU (AthlonXP).
BugFix: The message is not displayed properly when the SSE is not available.
ver 1.51 2011/07/06Sibilant noise processing/Pitch accuracy is improved.
BugFix: the 'Calib' paremeter is not work normally.
Scale setting menu is reflected the Scale buttons (still temporary work)
ver 1.50 2011/07/01New GUI, with the Pitch Graph.
More stable pitch and less artifacts by new PitchDetection/Shifting algo.
Less CPU load.
Added the Scale select button.
ver 1.27 2011/01/27BugFix: In some HOST (especially Audacity), some noise is generated if invoke KeroVee twice or later.
ver 1.26 2010/10/24SSE CPU check code is added. message will be displayed if cannot work.
Improved tolerability for input level-over.
Retune algo is improved, more natural correction.
'Chord mode' is added that will specify the multiple allowable note.
ver 1.25 2010/8/07Input freq range expansion is not work normally, re-fixed. Now, the soprano voice is work normally.
ver 1.24 2010/7/13Input freq range is expanded to soprano. Sound engine is a little improved. MIDI note handling logic is improved. Parameter step (ex. formant) become more granular.
ver 1.23 2010/6/06Amount parameter added. Sound engine has been improved: noise reduced / retune curve become natural.
ver 1.22 2010/5/17A little improved the sound quality (especially the pop noises).
ver 1.21 2010/5/08BugFix:May be crush if you use a host without GUI.
BugFix:In some case, sounds stop during tweaking parameters.
Improve the sounds of pitch-shifting
ver 1.20 2010/5/03Formant shift / preserv fucntion is added.
Transpose bug fixed.
