An example
As an example, consider this before-and-after graphic representation of
the pitch of a vocal phrase that contains both vibrato and expressive
gestures.
In the original performance, we can see that although the final note
should be centered around D, the vocalist allowed the tail of the note to
fall nearly three semitones flat. The “after” plot is the result of passing
this phrase through the ATR-1a with a Program consisting of a D Major
Scale (with C and B set to ”Blank”) and a Speed setting of 10. That Speed
causes the pitch center to be moved to D, while still retaining the vibrato
and expressive gestures. (Setting C and B to ”Blank” is necessary to keep
the ATR-1a from trying to correct the seriously flat tail of the last note to
those pitches. See Chapter 4 for more details.)
Program Mode vs. Song Mode
At its top level, the ATR-1a operates in one of two modes, Program Mode
or Song Mode. Which mode you use depends upon your application and,
to some extent, how radical are the required corrections.
Program Mode
In Program Mode, you call up one of the ATR-1a’s 50 individual Programs
to control the correction algorithm. Each Program consists of a Scale, a
Speed setting and Vibrato settings. You can step through Programs with a
foot switch or via MIDI.
Use Program Mode when a single scale (or maybe two) is all that’s required
for a particular correction.
