About Signal Processing
The built-in effects processor of the QuadraSynth is similar to that of the Alesis
QuadraVerb, capable of generating multiple, fully digital effects simultaneously. The
QuadraSynth effects processor has four inputs, or effect sends. You might think of
these as the typical post-fader sends found on a mixing console. In a Program, each
of the four Sounds can be assigned to one of the four effect sends. In a Mix, each
Program can use its own effects routing or you may override this and assign the
entire Program (all 4 sounds) to one of the four effect sends. Once you assign a Sound
(in Program Edit) or a Program (in Mix Edit) to an effect send, you can adjust the
Effect Send Level.
To route a Sound/Program only to an effect send, and not the Main or Aux outputs, assign
the Output parameter of the Sound/Program to ÒOFF,Ó assign its Effect Bus to one of the
four effect sends, and adjust the Effects Level.
The configuration determines the arrangement of effect functions of each effect send.
Imagine a configuration as an arrangement of multiple effects processors patched
together at the end of each effect send. Example: In one configuration, effect send 3
has its own separate reverb, while in another configuration it has its own delay and a
level control feeding a reverb shared with send 1. When youÕre programming effects,
you will need to refer to the charts on pages 91Ñ95 for the effect configuration youÕre
using, so you know how the paths from different effect functions interact.
The Effect functions consist of: Pitch, Delay and Reverb. Each function has several
types to choose from. For example, the Pitch effect can be either a chorus, a flange, a
resonator, etc. The Reverb can be a large hall, plate, gated, etc. The parameters
available for an effect function depend on the selected effect type. Some effect types
have very few parameters, while others have many. For example, the stereo delay
effect has about twice as many parameters as the mono delay effect (since the stereo
delay has two adjustmentsÐ left and right Ð for several parameters). Consequently,
the more parameters an effect has, additional pages become available for that
function. The number of pages the currently selected function has, and the current
page are always shown in the bottom left of the display.
Each effect has stereo outputs, which may be routed to the Main Left and Right
outputs using the Mix function (the Aux Left and Right outputs do not use the
internal effects processing).
