In discussing 300 operation, the following terms are used.
Algorithm
The 300 contains eleven algorithms. An algorithm is a set of instructions that tells
the 300's audio processors how to process the input signal. One algorithm
produces pitch shift effects, another produces reverberation, etc. Algorithms are
stored inside the 300 on ROM (Read-only memory) chips.
Configuration
The 300 can deliver two effects (one from each machine) simultaneously. The
manner in which the two machines relate to each other is called the
configuration.
The machines can be used with independent inputs and outputs (Dual Mono
configuration), they can share the same stereo input signal (Single configura-
tion), or the outputs of one machine can be fed into the input of another (Cascade
configuration).
Effect
An effect consists of an algorithm, the parameter values which create a specific
sound, four associated patches, and an identifying name.
Machine
The 300 contains two processing modules, called Machine A and Machine B.
Although both machines can run simultaneously, only one can be accessed from
the front panel at any given time. A dedicated function key labeled MACH allows
front panel selection of either Machine A or Machine B.
Pages
Because effects (and other modes of operation) have more parameters than can
be displayed at one time, parameters are grouped into several
pages. You move
between pages by pressing the dedicated function keys labeled PAGE UP and
PAGE DOWN.
Parameter
Each algorithm has a set of
parameters (controls) that uniquely characterize it.
The settings of the parameters can be changed to create radically different
sounds from a single algorithm.
Patch
A patch is a routing assignment that allows one of the 300's parameters to be
driven by a source controller (LFO, footswitch, mod wheel, etc.)
Register/Preset
Registers are simply memory locations where you can store your own setups and
effects.
Presets are factory-installed setups and effects. The presets cannot be
overwritten, but they can be modified and stored as custom setups in the
registers. Registers and presets are differentiated on the 300 display by the initial
R (Register) or P (Preset) before their number.
