Auto-Tune Evo MIDI Functions
scale containing only those notes that appear in
the melody.
To use the Learn Scale From MIDI function,
ensure that the desired MIDI source is routed
to Auto-Tune Evo and then click the Learn Scale
From MIDI button. Its color will change to blue
and the Edit Scale display will automatically be
set to a chromatic scale with all of the notes set
to Remove.
Now simply play the melody to be corrected
from your keyboard or sequencer. Tempo and
rhythm don’t matter, so take your time and
make sure you don’t play any wrong notes.
As each note is played, the corresponding
Remove button in the Edit Scale Display is
turned off (adding that note to the scale as a
Scale Note). Assume, for example, that your
melody starts with D, B, and then A. After
playing those notes the display would look like
this:
When you have played the entire melody, press
the Learn Scale From MIDI button again to end
the process. The Edit Scale Display will now
contain a scale containing only those notes that
appeared in your melody.
Auto-Tune Evo provides two functions that
require it to receive MIDI data from the host
application. Depending on your intent, this data
could come in real time from a MIDI controller
(typically a keyboard) or from a prerecorded
MIDI sequencer track. Refer to your host
application’s manual for details on how to route
MIDI to Auto-Tune Evo.
Please note that some host applications may
not support the routing of MIDI information to
plug-ins. In that case the MIDI functions will
not be selectable.
Instance ID
Some host applications assign numerical
instance IDs to multiple instances of the same
plug-in. If your host does this, the ID will appear
in an orange display in the lower left-hand
corner of the MIDI control area. Instance IDs
are useful when you are using any of Auto-Tune
Evo’s MIDI functions, as they allow you to
be sure that you are routing the MIDI stream
to the correct instance of Auto-Tune on the
desired track.
Learn Scale From MIDI
In most cases, you will probably tell Auto-Tune
Evo which notes are valid scale notes using the
Key and Scale popups, the Edit Scale Display
and/or the Virtual Keyboard. However, there
may be occasions when it is not clear exactly
what key a melody line is in, or where the
melody line has too many accidentals to fit
comfortably into a conventional scale. For those
occasions, the Learn Scale From MIDI function
allows you to simply play the melody into Auto-
Tune Evo from a MIDI keyboard or sequencer
track and let Auto-Tune Evo construct a custom
