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.
