mixer, and is variable so that you can change the balance of that
particular effect with respect to the overall sound.
The effect input can come from the main input if you only want the
effect to process the dry sound, but in many configurations, the effect can
get its input from the output of other effects, or from a combination of
processed and dry sounds.

Modulation

As mentioned earlier, many QuadraVerb GT parameters can be changed
in real time via pedals that generate continuous controller commands,
or from commands issued by a sequencer or synthesizer. Continuous
controller pedals are available from a variety of manufacturers at
various price points. These generate signals that are ÒtaggedÓ with a
particular controller identification number. If you set a QuadraVerb GT
parameter to be controlled by this particular controller number, moving
the pedal will change the QuadraVerb GT parameter.
Modulation consists of choosing up to 8 ÒtargetÓ parameters to be
modulated by any one of several types of MIDI ÒsourceÓ data types (pitch
bend, aftertouch, note number, and note velocity as well as continuous
controllers). Several parameters can be changed by one controller, so
that, for example, moving a pedal could increase chorus depth and boost
the midrange frequencies.
ÒBi-TimbralÓ Effects
The QuadraVerb GT can serve as two separate effects units by proper
patching to and from the effects loop. For example, consider a situation
where a guitarist plays guitar and sings. Plug the guitar into the
QuadraVerb input; the effects loop send provides the post-analog effects
signal, which can be routed to a guitar amp. Meanwhile, the voice mic
can be externally preamplified and sent into the effects loop return. This
allows the vocal to be processed by the digital chorus, reverb,
equalization, etc. sections. The QuadraVerb GT output, which now
carries only the processed vocal sound, can be routed to a PA for further
amplification.
