Editing Effects: Chapter 7

QSR Reference Manual 16

PITCH

The Pitch function is used to edit Pitch parameters.

Pitch Type Page 1

The Pitch Type function allows access to 6 pitch altering modes. The Pitch types

available are: Mono Chorus, Stereo Chorus, Mono Flange, Stereo Flange, Pitch

Detune and Resonator. Although some of these effects can sound similar to one

another depending on the parameter settings, each is achieved differently and can be

quite dramatic under the right circumstances. Pitch effects are achieved by splitting

the signal into two parts, effecting the pitch of one of the parts, then mixing them

back together. This eventual mixing is essential since the overall sound of the effect is

achieved by the actual difference between the normal, uneffected signal and the

effected signal.

Type: MN CHORUS

So that you can better understand the differences between the Pitch type effects, and

therefore better apply them to your music, here is a brief explanation of each.

Mono Chorus. The Chorus effect is achieved by taking part of the signal, slightly

delaying it, and then slightly detuning it as well. The detuning is further effected by

being modulated by an LFO which causes the detuning to vary. Many variables are

available in this scheme. The LFO depth can be varied, the LFO speed can be varied,

and a portion of the detuned signal can be fed back to the input to increase the effect.

Finally, the waveform shape of the LFO can be changed from a smooth triangle to a

more abrupt squarewave to make the pitch detuning more pronounced.
