The Wiring Algorithm (ALG) Page

The PC4's algorithms are the core of VAST programs (Variable Architecture Synthesis
Technology). Use the Wiring Alg page to select an algorithm and route DSP (digital signal
processing) functions for the current layer. Several DSP functions are available including
filters, equalizers, oscillators, amplifiers, mixers, panners, distortion, shapers, and aliasers.
DSP functions contain adjustable parameters which can be set to a single setting, or
controlled by a physical controller or other control source (such as an LFO or envelope).
Algorithm
Use the Algorithm parameter to select an algorithm by ID number. A diagram of the selected
algorithm is shown in the center of the page, showing the selected DSP functions and audio
signal flow wiring. In the diagram, the audio signal flows through each DSP block from left
to right.
Depending on the algorithm, the signal may split into two wires, enabling part of the signal
to bypass certain portions of the algorithm. Split wires may rejoin within the algorithm, or
they may pass all the way through as split signals.
Each of the factory algorithms represents a preset signal path. See the
(Dynamic VAST) on page 3-51
paths.
Caution: Changing a layer's algorithm can affect the layer's sound drastically. It's a good idea
to turn down the volume of your PC4 or your sound system before changing algorithms.
