Panning And Tremolo; Ring Modulation; Tunable Resonators; Sampling - Alesis GT Reference Manual

Panning and Tremolo

Panning shifts the signal back and forth between the stereo outputs at a
cyclical, adjustable rate. Tremolo provides a ÒpulsingÓ sound via cyclical
level changes. Both have ÒdepthÓ parameters; with panning this varies
the width of the pan in the stereo field, with tremolo this sets the
difference between volume peaks and valleys.

Ring Modulation

Ring modulation shifts a signal's harmonics up and/or down by an
adjustable frequency (expressed in Hertz). The QuadraVerb GTÕs ring
modulator features individual outputs for the up and down signals. The
resulting sound takes on a Òclangorous,Ó bell-like quality that is used
mostly with percussive effects. Try this on a drum machine, or muted
guitar parts.

Tunable Resonators

A resonator is a filter whose response is so sharp that it actually imparts
a pitch to any signal going through it. In the Resonator configuration,
there are up to five resonators, depending on the configuration, so you
can tune the resonators to complex chord types. You can also transpose
the resonator frequencies via MIDI notes to match a particular chord
progression.

Sampling

Sampling is the process of digitally recording a signal into the
QuadraVerb GT's memory, which can then be triggered via an external
audio input (e.g., a snare drum sound coming from a tape track), a front
panel button, or a MIDI note. Different MIDI notes will transpose the
sample. Sampling is useful if you want to capture a particular effect or
chord change, then play over it. Try it in the studio for drum sound
replacement, reproducing unusual vocal effects, etc.
