TREMOLO
Tremolo is a rhythmic change in loudness, commonly
employed as an expressive technique by vocalists and
wind instrument players. It is also one of the oldest
effects, frequently used with electric guitar, electric
piano, and occasionally vocals. Different tremolo effects
are largely determined by the rate (fast or slow) and
waveform shape (smooth or sharp) of the change in
loudness. If the effect is used in a stereo mix, the left and
right can be synchronized to produce dramatic side-to-
side motion.
The Tremolo programs offer classic tremolo shapes, such
as square, sawtooth, triangle, sine, and rectified sine. The
synchronization of the left and right channels can be
adjusted to produce mono and stereo effects. The Tap
button sets tremolo rates, making it simple to match the
tempo of the music. The "Adjust" parameter (Phase) sets
left and right channel waveforms out-of-phase, resulting
in a panning motion.
Set the Mix parameter to Wet for all programs. Mix can
be used to effectively set the depth of the Tremolo
program when more dry is added to the wet-to-dry mix.
It is recommended to make the rate work with the
tempo of the music, as Tremolo is essentially a rhythmic
effect.
