MODULATION EFFECTS

The next group of pages deal with the modulation effects. These include effects such as

chorus, flanging and phase shifting. Also in this section are pitch shift, rotary speaker

emulation effects and autopanning. The modulation effects section screen looks

something like this:

You must first choose which type of modulation effect you want to use in the

field. The choices are

PHA/FLA/CHOR This selects that the modulation effects are phasing, flanging or

chorus.

ROTARY SPKRS This selects that this section of the effects will create rotary

speaker emulations.

FMOD/AUTOPAN This selects that this section of the effects will give autopanning

and frequency modulation effects.

PITCH SHIFT This selects that this section of the effects are for creating pitch

shift and detune effects.

PITCH + FBK This selects that this section of the effects are for PITCH SHIFT

with the delayed feedback.

CHORUS, PHASE SHIFT AND FLANGING EFFECTS

If you select PHA/FLA/CHOR, the screen will be as above. The parameters you may set

for phasing, flanging and chorus are all the same but the actual algorithm used for each

effect type is slightly different and so yields a different sounding effect. All these effects

are produced by modulating a short delay with a low frequency oscillator. All these effects

are stereo. In the PHASING and FLANGING effects, each side of the stereo image is

modulated in anti-phase (i.e. one channel’s control signal is fed via an inverter so that as

one channel goes up, the other goes down) to give great depth and stereo width to a

sound (the CHORUS effect is more complex and is described in detail on the next page).
