AUTOPAN AND FREQUENCY MODULATION EFFECTS

If you selected FMOD/AUTOPAN in the field, this selects the autopanner and

frequency modulator. This will cause the sound to pan backwards and forwards from left

to right and back again. You may also add pitch sweep effects to this to create Doppler

effects. You will see this screen:

The FMOD parameters are:

This sets the speed of the frequency modulation.

This sets the amount of frequency modulation.

This sets the amount of feedback from the output of the frequency

modulator back to its input. This parameter can be used to accentuate the

frequency modulation effect.

The AUTOPAN parameters are:

This sets the speed of the autopan effect.

This sets the ‘width’ of the autopan effect. With high settings the sound will

pan across a wider stereo image.

This sets the type of the autopan effect. The choices are:

The sound will move from left to right. As the sound crosses the

central axis, however, the effect is of the sound ‘rotating’’ (i.e. as it

goes from left to right, the sound becomes more distant and as it

travels from right to left it becomes more ‘up-front’ and forward).

As above but in the opposite direction.

The sound will move from left to right but, as the sound crosses

the central axis, the level will be constant giving the impression of it

simply panning left to right.

The output of the autopanner is mono and the effect is a tremolo

effect (i.e. mono amplitude modulation)

This effect selection can be used to produce many different sounds. It can used as an

ordinary autopanner (i.e. FMOD parameters all set to 00) or to create vibrato and chorus

effects (using just the FMOD parameters; AUTOPAN parameters set to 00) or, using both

panning AND frequency modulation, you can create a Doppler effect (i.e as the sound

moves, it also changes pitch - the classic ambulance siren effect!).

NOTE: Because the stereo mod section passes through the echo section, any stereo

mod effects you create here will be ‘monofied’ when mono delay effects are selected. As

a result, you cannot effectively use autopan with mono echo.
