The Effect Devices

217

Tip: Using the CF-101 as a vibrato effect

The Send mode is intended for when using the CF-101 as a send effect. In this

mode, the device will only output the modulated delay signal - the actual “cho-

rusing” is obtained by mixing this signal with the dry, unprocessed signal in the

Mixer.

However, if you activate Send mode while using the device as an insert effect,

the result will be a pitch modulated version of the original sound - in short, a vi-

brato effect. Along with a little feedback, this can be used for special effects.

PH-90 Phaser

The PH-90 Phaser is a classic phaser effect with some special features for fine-

tuning the sound. It can create the classic sweeping phaser sounds suitable for

pads or guitars, but also more extreme effects if you like. The phaser is best

used as an insert effect.

Theory

A phaser works by shifting portions of the audio signal out of phase, and then

adding the processed signal back to the original one. This way, narrow bands of

the frequency range (“notches”) are filtered out. When these frequencies are ad-

justed, a sweeping phaser sound is created.

The PH-90 is a four-stage phaser, which means that there are four “notches” in

the frequency response curve (this is a little like using four notch filters with dif-

ferent filter frequencies - see page 108 for an explanation of notch filters).

When the phaser frequency is adjusted (manually or by the built-in LFO), these

notches will move in parallel in the frequency spectrum. Furthermore, you can

adjust the distance between the notches (Split) and their Width. Adding feed-

back raises the filter gain just below each notch in the frequency range, creating

a more pronounced effect.
