TremoloThe MPX 100 tremolo variations offer a
variety of tremolo shapes (square, sawtooth,
triangle, sine and rectified sine). The syn-
chronization of the left and right sides can be
adjusted to produce mono and stereo ef-
fects. As the tremolo rates of several varia-
tions are set with Tap, it’s easy to match the
tempo of the music. Other variations let you
set left and right channel waveforms out-of-
phase, resulting in a panning motion.
All of the variations of this program (1-8)
should be used with Mix set to fully Wet. By
adding more dry to the wet/dry mix, Mix
effectively sets the depth of the Tremolo.

Tremolo is a rhythmic change in loudness, commonly employed as an expres-
sive technique by vocalists and wind instrument players. It is also one of the oldest
electronic effects — frequently used with electric guitar, electric piano and,
sometimes, vocals. Different tremolo effects are largely determined by the rate and
waveform shape of the loudness change (fast or slow, smooth or sharp). If the
effect is used in a stereo mix, the left and right can be synchronized in a variety of
ways to produce dramatic side-to-side motion.

4 Rectified Sine Wave Sweep: 0, 90, 180, 270 Rate (1/8 Note)
5 Square Wave Sweep: 0, 90, 180, 270 Rate (1/8 Note)
6 Sawtooth Wave Sweep: 0, 90, 180, 270 Rate (1/8 Note)
7 Triangle Wave Sweep: 0, 90, 180, 270 Rate (1/8 Note)

As tremolo is essentially a rhythmic effect,
care should be taken to make the rate work
with the tempo of the music.
