Detune effects are useful for

thickening up sounds by adding
delayed/pitch shifted versions of
the original source. They can be
particularly effective when used to
simulate double-tracking. They
are also great alternatives to cho-
rus effects as a detuner can add
the richness of a chorus effect
without the audible sweep caused
by the chorus rate. Detuners are
also traditionally used to turn a six-
string guitar into a twelve-string, or
an in-tune piano into a honky-tonk.
The MPX 1 detuners are optimized
to provide very fine amounts of
pitch shift.

Detune (M) is a single-channel

detuner that creates a pair of sig-
nals, pitch-shifted up and down
from the input. The pair is always
mixed together, and presented
equally to the outputs.

Detune (S) creates a pair of sig-

nals, pitch-shifted up and down
from the inputs. The left and right
channels are separate.

Detune (D) sums left and right

inputs to mono,then creates two
pairs of signals, pitch-shifted up
and down from the inputs by Tune1
and Tune 2. The first pair goes out
the left, the second pair out the
right.

Pitch Effects

In the Pitch effects: Detune (M), (S) and (D) and Shift (M), (S) and (D), Tune controls the
amount of pitch shift. The Optimize parameter (an option of Tune) allows balancing of any
artifacts vs. the amount of delay through the effect. Higher settings of Optimize are good
for chords and low notes, lower settings minimize the delay through the effect.

A set of Volume effects: Volume (M), (S) and (D) are included in this block for convenience
when constructing programs that don't use pitch effects. A sine wave generator (Test
Tone) is also included to allow generation of test tones, tuning, etc.

* = Interpolated; ( ) = Option of preceding parameter

As the detune effects use up relatively few processing resources, they can be combined with
reverb and many other effects. When creating effects that don’t require pitch shifting by large
intervals (semitones) the detuners are the most efficient choice.
