Tutorial 4: Using the Automatic Mode MIDI Functions
This tutorial will introduce you to Auto-Tune
Evo’s two Automatic Mode MIDI functions:
Learn Scale From MIDI and Target Notes Via
MIDI.
With Learn Scale From MIDI, you can create
the correct scale for a particular melody without
knowing a G-sharp from a B-flat. Simply play
the melody on a MIDI keyboard which is
patched through your host application to Auto-
Tune Evo or play an existing MIDI file with
contains the MIDI notes of the melody to be
processed.
Begin the tutorial by doing the following:
1. Load or import the audio file “somewhere”
into a track of your host program. This is a
recording of Somewhere Over the Rainbow
sung with fairly extreme pitch errors. (Our
very talented singer made us promise to
tell you that she did this on purpose at our
request.)
2. Set up Auto-Tune Evo to be an insert effect
on that track.
3. Import the MIDI file “somewhere.mid” into
your host program’s MIDI sequencer.
4. Select Auto-Tune Evo as the target for the
MIDI track.
5. Select Automatic Mode and click the
“Learn Scale from MIDI” button so that
it turns blue and its indicator changes to
“On.”
6. Click the All Octaves button so that it turns
blue (if it is not already).
7. Play the MIDI file through once and watch
as the scale develops on Auto-Tune Evo’s
virtual keyboard and in the Scale Edit
window. As each note is sung, it is added
to the scale until the scale includes every
note that appears in the melody.
8. Set the Retune control to 20 and play the
audio track using this scale.
NOTE: You can also instantaneously
define a scale by playing all of the
notes of the scale as a chord (i.e.,
all scale notes played on the same beat) and
recording that into a MIDI track. This is an ideal
way to use Auto-Tune Evo in music with many
key (scale) changes.
With Target Notes Via MIDI, Auto-Tune Evo
looks at its MIDI input in real time to determine
its current target note(s). Try the following with
the provided audio and MIDI files:
1. Set up your host program and load or
import the “somewhere” audio and MIDI
files as described in steps 1–4 above.
2. Select Automatic Mode and click the
“Target Note Via MIDI” button so that
it turns blue and its indicator changes to
“On.”
3. Click the Octaves as Played button so that
it turns blue (if it is not already).
4. Play the audio and MIDI track together and
watch the current target note change in real
time on the Virtual Keyboard — and listen
to the results.
The most interesting part of the Target Notes
Via MIDI feature is that it only operates for the
duration of the MIDI note — that is, when there
is no current MIDI Note On value, Auto-Tune
Evo is effectively in Bypass mode. This means
that if you delay the MIDI notes, then the audio
performs its attacks as performed and then
corrects to pitch when the MIDI note occurs
(at whatever Retune Speed is set). In the case
of the ‘Somewhere’ vocal performance, most
of the intonation problems happen during
the notes’ sustain portions. Try moving the
notes in the MIDI file around and listen to the
results. This gives far more subtle control than
Automatic Mode alone, while not being quite
as tweaky as operating in Graphical Mode.
NOTE: The MIDI functions look only
at MIDI note values. Controller data
such as Pitch Bend or Mod Wheel do
not affect Auto-Tune Evo’s performance.
