Auto-Tune 8.1.8 VST PC Notes
Thank you for purchasing or evaluating Auto-Tune 8.1 VST for PC. While the
Owner's Manual contains all the platform-independent information you'll need
to get the full benefit of Auto-Tune 8.1 (and we really encourage you to read
it), this file includes specific installation and use issues unique to the VST PC
version.
ANNOUNCING AUTO-TUNE 8.1
Auto-Tune 8.1 contains improvements to the timing of the Graph Mode data,
fixing long-standing issues with that data, especially at higher sample rates and
in longer songs. We think you will appreciate the ability to more accurately
track and correct your audio using this new software!
INSTALLATION
The Auto-Tune 8.1 VST installer will automatically install the plug-in in the
standard VST3 plug-in folder(s). On 32-bit systems, and for the 64-bit version
of the plug-in, this is in Program Files/Common Files/VST3. For the 32-bit
plug-in on a 64-bit system, this is in Program Files (x86)/Common Files/VST3.
All documentation files will be installed in Program Files/Antares Audio
Technologies/Auto-Tune 8.1 VST on a 32-bit system, or Program Files
(x86)/Antares Audio Technologies/Auto-Tune 8.1 VST on a 64-bit system.
AUTHORIZATION
Authorization is the process by which this software is allowed to run on your
computer. Detailed instructions covering the available authorization options will
be found in the file “Authorization Read Me” which is included on the
installation CD ROM or with your software download.
NOTE: You will not be able to launch Auto-Tune 8.1 until you have completed
the authorization process and downloaded your authorization to your iLok
smart key.
VERY IMPORTANT NOTE
For those upgrading from older versions of Auto-Tune, it is critical to note the
following:
Auto-Tune 8.1 will NOT open sessions created with ANY previous versions of

Auto-Tune. Improvements to the timing of the Graph Mode data make that


data incompatible with the data from any earlier versions, including previous
Auto-Tune 8 versions (whose version number starts with 8.0).
For that reason, we have configured Auto-Tune 8.1 such that it and Auto-Tune
8 and any existing version of Auto-Tune can be active in your audio host
simultaneously (provided that version is compatible with your audio host). The
new software will be found under its new name, “Auto-Tune 8.1”.
You can begin using Auto-Tune 8.1 for all your new sessions, while at the
same time continuing to use your old sessions with the old software (including
versions of Auto-Tune 8 prior to 8.1).
Alternatively, you can use whatever method your host offers (bouncing,
offline editing, etc.) to permanently render the corrected tracks of your old
sessions (using the old software), and then use Auto-Tune 8.1 for any future
edits.
DO NOT CHANGE THE LATENCY SETTING WHILE THE TRANSPORT IS RUNNING
Seriously. Don't do it.
SUPPORTED VST HOSTS
While we have tested Auto-Tune 8.1 with most major VST hosts, given the
huge variety of available hosts, we cannot guarantee that Auto-Tune 8.1 will
function properly in every one. For the current list of supported hosts, consult
our online Host Compatibility guide at:
/>NOTE OBJECT PITCH PREVIEW IN CUBASE
In order to hear pitch previews when moving Note Objects in Cubase, you must
uncheck the Preference option, "Disable VST3 plugins when no audio present."
This option is checked by default, so you will not hear previews until you
manually disable it.
GRAPH MODE SYNC IN SONAR X3
In Sonar X3, changing the playback location while the transport is playing will

cause loss of sync in Graph Mode. To maintain sync, stop the transport, move to
the desired location, and put the transport back into play.
GRAPH MODE POSITION INDICATOR SYNC
In some hosts, the audio playback will lag slightly behind the graphical position
indicator. This is an artifact of some host and/or hardware combinations and is
out of our control. It is a cosmetic issue only.


MODIFIER KEYS
The following modifier keys are active in Auto-Tune 8.1 in various VST hosts:
Shift - Toggles Snap-To-Note state in Graph Mode. Toggles Momentary state in
Automatic Mode
Control - Allows free movement of correction curves in Graph Mode. Toggles
Magnifying Glass function (+/-) in Graph Mode
1 - 0 - Graph Mode function selection (QWERTY keys only)
Control - Cut, Copy, Paste, Undo and Redo

CHANGES FOR VERSION 8.0.4
The following changes were made for version 8.0.4:






Fixed a potential crash observed sometimes when closing the audio host.
Fixed the names of certain notes in the E Major and B Major scale on the Graph
Mode keyboard.
Fixed the hiding of the envelope in the main graph when Show Lanes is selected.
Fixed an issue where the default window size was not being retained.

Fixed the Update Checker so that it correctly recognizes new update versions.

CHANGES FOR VERSION 8.0.5
The following change was made for version 8.0.5:


Fixed the version number used to check for updates so that you will not keep getting
update notifications when you have already updated your software.

CHANGES FOR VERSION 8.0.6
The following changes were made for version 8.0.6:






Improved the processing of certain types of audio, especially with certain higherpitched instruments.
Fixed a potential time-stretching problem at higher sample rates.
Fixed a problem at higher sample rates with the notes generated when dragging an
existing Note Object in Graph Mode.
Fixed dragging of correction objects to prevent minor changes in their horizontal
(time) position when attempting to alter only their vertical (pitch) position.
Added a checkbox in the Options dialog to allow turning off/on automatic update
checks, along with a button to check for updates immediately.


NOTE REGARDING USE FORMANTS SETTING
In making the fix in version 8.0.6 for certain types of audio, a change was made
in how the Use Formants setting is implemented. This will result in audio

glitches if you change the setting during playback while processing audible
audio. To avoid such glitches, you should always change this setting either
when the transport is not running, or during silent moments of the audio.
CHANGES FOR VERSION 8.1.0 (AUTO-TUNE 8.1)
The following changes were made for version 8.1.0:







Fixed several issues in the placement in time of Graph Mode data,
especially at sample rates other than 44.1K (or its multiples), as well as
when tracking pitch starting at different locations in the timeline.
Fixed a delay problem when applying time changes.
Fixed a problem where certain parameters would not be properly restored
when loading sessions that were saved while in Graph Mode.
Fixed an issue where the new check box for automatically checking for
updates would not retain its value.
When completing a tracking operation in Graph Mode, the graph will now
only zoom to the newly tracked data if the Auto Scroll button is turned on.

CHANGES FOR VERSION 8.1.1
The following changes were made for version 8.1.1:





Fixed an issue where the Graph Mode keyboard would not refresh the
labels on its keys when changing the Key or Scale until the graph was
scrolled (or otherwise redrawn).
Fixed a memory “leak” in the graphical correction objects.
Fixed a bug that could sometimes lead to a crash when generating or
drawing new curves on top of existing curves.

CHANGES FOR VERSION 8.1.2
The following changes were made for version 8.1.2:




Fixed an issue with using the Bass Instrument setting where some audio
data could cause a crash.
Modified the Show Lanes button so that it disables when not using Major,
Minor or Chromatic scales.
Disabled Auto-Tune’s “Key Bindings” (i.e., hot keys) whenever the mouse is
being tracked using a Graph Tool or when adjusting the Number of Note
Objects, Retune Speed, Adjust Vibrato or Throat Length Adjust knob in
Graph Mode.


CHANGES FOR VERSION 8.1.4
The following changes were made for version 8.1.4:




Greatly improved the graphical performance in all areas, especially when

the plug-in window has been expanded above the minimum (default) size.
Fixed a bug where switching to Graph Mode and back to Automatic Mode
caused the processing to act as if the Retune Speed were set to 0 (Fast).
Added an option to disable the use of custom cursors while the transport is
running, for people whose systems would produce audio artifacts if the
mouse is moved while the transport is running in Graph Mode.

CHANGES FOR VERSION 8.1.5
The following changes were made for version 8.1.5:


Disabled the Graph Mode text readouts Cursor Time, Output Pitch, Object
Pitch and Detected Pitch while the transport is running to avoid glitches and
scrolling delays seen on some systems.

CHANGES FOR VERSION 8.1.6
The following changes were made for version 8.1.6:



Fixed a problem saving session data that includes Graph Mode pitch
correction curve objects.
Fixed an issue where if the session were saved while in Graph Mode, then
upon re-loading the session, the pitch correction would not follow the
correction data exactly until the user switched to Automatic Mode and back
to Graph Mode. (It would sound as if the Retune Speed was set
incorrectly.)

CHANGES FOR VERSION 8.1.8
The following changes were made for version 8.1.8:








Fixed a problem with the Line Tool when moving the mouse near or beyond
an edge of the graph while drawing lines. It now behaves as expected,
whether the mouse button is held down or released between points.
Fixed the Object Cents display so that it shows the correct value when
dragging existing Note Objects.
Fixed a problem where if Show Lanes was turned on and the envelope was
set to NOT be drawn in the main graph, then scrolling vertically would make
all the graphical data disappear from the graph until some other action
caused it to redraw (such as scrolling horizontally).
Fixed the dragging of Note Objects when Snap To Note is turned on for the
Major and Minor scales. Previously, it would allow dragging to notes that
are not in the current Major or Minor scale.







Fixed a minor drawing issue with the drawing of “lanes” when Show Lanes
is on and scrolling up or down.
Fixed an issue with certain input devices such as the MagicMouse and
trackpad under OS X 10.12 (Sierra), where mouse movements of under a

pixel would go completely undetected. This caused issues with some of the
graph tools when moving the mouse slowly.
Fixed minor issues with formatting in the various pitch-reporting text boxes
in Graph Mode.
