E. PITCH CHANGE SECTION
Pitch Change effects involve splitting the input signal into at least two separate signals, then modifying the
pitch of one signal and mixing it back together with the unaltered direct signal. The Intellifex LTD offers two types
of pitch change effects: Chorus and Pitch Shift.
CHORUS
The Chorus effect is achieved by using one or more delayed signals, detuning
these delayed signals (slightly changing their pitch) then modulating this detune effect
so that the amount of pitch detune is constantly varying. Using many delayed signals
at different delay lengths - as well as using different detune amounts, modulation rates
and modulation depths for each delayed signal - results in a rich, spacious stereo
chorused signal.
CHORUS PARAMETERS
Level (Individual Voices)
This parameter adjusts the volume of the delayed signal relative to the other
voice(s) of the effect and is included in the parameter list for each voice (or
each delay signal) of both the 8-Voice and 4-Voice Chorus effects. (This level
control is not the same as the Chorus Level found in the Mixer function param-
eter list.)
Pan
The Pan parameter allows you to pan each voice (or delay) of the chorused
signal to the left or right channel. This parameter is adjustable from 0 to 100 -
where 0 = full left, 100 = full right and 50 = center.
Delay
The Delay parameter determines the delay time (in milliseconds) for each tap
of the chorus signal. It is this delayed signal that is detuned and modulated to
produce the chorus effect. Using shorter delay times for this effect produces a
tighter sounding chorused signal, while using longer delay times will achieve a
much larger, ambient effect.
Depth
The Depth parameter adjusts the amount of modulation of each delayed
signal. A lower depth setting will produce a more subtle detune effect while a
higher setting of this control will cause a more drastic detuning of the delayed
signal.
Rate
The Rate parameter determines the sweep speed for the delayed signal (i.e. the
speed at which the delayed signal is modulated). Here a low rate results in a
slow speed and a higher rate results in a faster speed.
