Glossary
A preset is a combination of an algorithm (or algorithms) and the associated parameter
settings. You select a preset to put different effects into the Units. Selecting a preset may
load effects into Units A, B, C, and/ or D. Presets affecting more than one unit also
contain signal
routing information.
There are four types
of presets in the DP / 4. They differ in how many units are affected,
and how many routing parameters are remembered . The type(s) of presets available for
selecting
depends on the current Config. The four preset types are:
Preset Type:
(1 U) 1 Unit Preset
(2U) 2 Unit Preset
(4U)
4 Unit Preset
(Config) Config Preset

There are 400 presets in the DP / 4; 100 presets (storage locations) for each type of preset.
The first
50 presets (00 to 49) are user programmable (battery backed up RAM). Presets
50 to 99 are ROM factory presets. These groups of 50 presets are referred to as Preset
Banks.

The RAM presets are loaded with factory defaults when the unit is shipped and
whenever it is reinitialized. These default presets may be recalled into RAM at any time
using a special command described in the System • MIDI section.
Multiple echoes
and reflections that combine to create an ambient effect. Different
devices
have been used to simulate these ambiences: springs, plates, tubes, and
chambers. The DP / 4 used digital algorithms to create new envirorunents and simulate
these classic ambiences.
