Throat Length 
Adjust
To give you 
maximum 
control over the 
timbre of your 
vocal tracks, 
the Throat 
Length Adjust 
control lets you 
independently set the throat length of each 
individual correction object (Curve, Line or 
Note). While the overall Throat Length for 
your track is still set by the master Throat 
Length control in the Common Controls 
section, each correction object can have its 
own independent adjustment (either longer or 
shorter) as desired.
NOTE: Since each correction object can have its 
own independent Throat Length adjustment, 
the Throat Length Adjust control is only active 
when Formant Correction is enabled and at 
least one correction object is selected. 
The default Throat Length Adjust setting is 
 (in which case the object(s) will have the 
Throat Length as set by the master Throat 
Length control). Command (Mac)/Control (PC) 
clicking the slider will reset it to that value.
Graphical Mode MIDI Functions
New in Auto-Tune 
8 is the ability 
to record a MIDI 
input in Graphical 
Mode and use 
the recorded 
MIDI notes 
to create Note Correction Objects. This 
makes it extremely quick and easy to set 
the target notes of a known melody line 
or create harmony parts from the original 
vocal (although, if you’re often generating 
harmony parts, we highly recommend our 
Harmony Engine Evo Vocal Modeling Harmony 
Generator as the most ecient solution). 
Depending on your intent, the MIDI data could 
come from a prerecorded MIDI sequencer 
track or in real time from a MIDI controller 
(typically a keyboard) played during the pitch 
or pitch + time tracking process. 
Recording MIDI Information
The only thing you need to do to record MIDI 
data is to route your MIDI source to Auto-Tune 
8. 
NOTE: Although virtually all major 
hosts these days allow the routing of 
MIDI to plug-ins, there may still be a 
few hosts lurking out there that do not support 
it. If you happen to be using one of those, this 
MIDI function will not be available.
Once a MIDI source is routed to Auto-Tune 8, 
any MIDI Note On and Note O events from 
that source will automatically be recorded 
whenever you track pitch or pitch + time.
ANOTHER NOTE: Since only one Note 
Correction Object can exist at any 
time point on the Pitch Graph, the 
incoming MIDI data is recorded with “last note 
played” priority. What this means is that if two 
MIDI notes overlap at all, the later note’s Note 
On will also generate a Note O for the earlier 
note.
