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 SPKR This selects that this section of the effects will create rotary speaker
emulations.
AUTOPAN/FMOD 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).

These effects are chosen in the field and are as follows:
PHASING This gives a ‘swooshing’ effect. It uses a very short delay time which is
modulated by an LFO.
