The3OOcontains eleven a/gorifIxns. An algorfthm isaset of instructionsthattells
the 300's audio processors how to process the input signal. One algorithm
produces p&h shift effects, another produces reverberation, etc. Algorkhmsare
stored inside the 300 on ROM (Read-only memory) chips.

The 300 can deliver two effects (one from each machine) simuftaneously. The
manner in which the two machines relate to each other is called the configura-
fiofl. The machinescan be used with independent inputs and outputs (Dual Mono
configuration), they can share the same stereo input signal (Single configura-
tion), orthe outputs of one machine can be fed into the input of another (Cascade
configuration).

An effecrconsists of an algorithm, the parameter values which create a specific

The 300 contains two processing modules, called Machine A and A&chine B.
Aithough both machinescan run simultaneously,
only
one oan be accessedfmm
the fmnt panel at any given time. A dedicated function key labeled MACH allows
fmnt panel selection of either Machine A or Machine B.

Each algorithm has a set of parameters (contmls) that uniquely characterbe it.
The settings of the parameters can be changed to create radically dtterent
sounds from a single algortthm.

A p&h is a routing assignment that allows one of the 300's parameters to be
driven by a soume controller (LFO, footswitch, mod wheel, etc.)

effects. Presefs are factory-installed setups and effects. The presets cannot be
ovenvrftten, but they can be modified and stored as custom setups in the
registers. Registersand presets are differentiated on the 300 display by the infttai
R (Register) or P (Preset) before their number.
