Section 2 - Getting Started

Important: There are two ways that the OP /4 tells you which type of Preset you are
selecting:
•
In
Select mode, when you press any of the Unit buttons (A, B, C, or D), either 1, 2, or 4 of the
yellow Unit LEOs will light. The number of lighted LEOs corresponds to the type of preset
you will be selecting if you move the Data Entry Knob. The yellow Unit LEOs also tell you
which
~t(s)
will be loaded with a new algorithm if you select a new preset.
•
Also, the display gives you constant feedback. For all Preset types, the upper line of the
display shows the preset name. The lower line shows how many units are in the preset you
are selecting:
Dark Hall
I=I:Hall Reverb
In a 1-Unit preset, the lower
line of the display shows the
full name of the algorithm in
the preset, and indicates
which unit the preset will be
loaded into.

B:rev
In a 2-Unit preset, the lower
line shows the 3-letter
abbreviations for the
algorithms in both units,
and indicates which 2 units
the preset will be loaded into
(A&B or C&D).

In a 4-Unit preset, the lower
line of the display shows
3-letter abbreviations for
the algorithm in all 4 units.
By definition a 4-Unit preset
will load new algorithms into
all four units.
Of the four Preset types, the most powerful is the Con fig Preset. The Config preset lets you save,
and later recall, the current state of the OP / 4, including all algorithm, signal routing and mixing
information.
Selecting a Config preset will:
•
Reconfigure the OP / 4 inputs and outputs;
•
Change the signal routing between units; and
•
Load a new algorithm into each of the four
Units.
To select a Config preset:
1.
Press Select.
2.
If the Config LED is not already on, press Config.
3.
Move the Data Entry Knob. The Select LED flashes, indicating that you are previewing
presets. The display shows the available Config presets.
4.
When the display is showing the preset you want to load, press Select again. This selects the
preset, and the Select LED stops flashing.
Note:
In its default state, the OP / 4 only allows you to select among twelve Config
presets (ROM locations 50-61). These have been programmed to give you easy access
to the most commonly used configs.
When you want to select among more Config presets, or to save your own, you can "reveal" the
remaining 88 Config presets by turning the "Show 100 Config Presets" switch to Yes. This switch
(parameter 59 in System. MIDI mode) unveils functions which have been hidden to avoid
confusion for the first-time user.
