Mod Depth
The Mod Depth section controls the depth of the delay modula-
tion. The delay time is modulated by a simple sinusoidal LFO
(low frequency oscillator).
Depth
Sets the amount of modulation.
Spread
Varies the phase of the LFO applied to each (stereo) channel.
At 0.0, the LFOs are in phase i.e. the same modulation is applied
to each channel. At 0.5 the LFOs are exactly out of phase i.e the
LFO for channel 1 is at its maximum when the LFO for channel 2 is at its minimum.
The Spread setting is useful for creating ‘wide’-sounding effects from mono sources.
Mod Speed
The Mod Speed section controls the speed of the delay modula-
tion.
Speed
Sets the frequency (in Hz i.e. cycles per second) of the delay
modulation.
Envelope Modulation
The Envelope Modulation section controls the re-
sponse of the plug-in to the envelope (i.e. the loud-
ness) of the incoming sound.
For these features to work effectively
you should ensure that the signal level
going into the plug-in is appropriate.
Use the level meters - the signal should
be peaking into the yellow area at least.
