in this manual
In discussing 300L operation, the following terms are used.
Algorithm
The 300L contains eleven algorithms . An algorithm is a set of instructions that
tells the 300L's audio processors how to process the input signal. One algorithm
produces pitch shift effects, another produces reverberation, etc. Algorithms are
stored inside the 300L on ROM (Read-only memory) chips.
Configuration
The 300L 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 300L 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 key labeled PAGE.
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 300L'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 300L display by the
initial R (Register) or P (Preset) before their number.
