The LP has two operating modes: Master and Preset.
• Master mode allows you to access and change global parameters and other utility options.
A complete list of the Master mode functions and parameters is shown on page 26.
• Preset mode allows you to access the presets and manipulate the sound from the front panel
controls. The Preset mode is the main operating mode for editing and playing the LP. Information
on Preset mode is found on page 23.
When the LP is powered on, it starts up in Preset mode. In
this mode, you select presets using the VALUE encoder. You
can rotate the VALUE encoder to step through the presets
in either direction. Pressing the encoder while rotating
increments the preset selection by +10 or -10 presets.
In
Preset mode, you’ll see the current preset displayed on the
top line of the LCD display, and a ‘Preset Active’ message on
the bottom line. The PRESET button is illuminated in amber.
When you edit a preset, the bottom line of the display changes
to ‘Panel Active’ and the PRESET button changes from amber
to red, indicating that you are editing the preset sound. By
pressing the PRESET button you can toggle between the
preset (stored) and edited (panel) sounds. Note that once
you change preset numbers, any edits made to the previous
preset will be lost unless the edits are saved.
Editing a preset is simple. There are four analog editing controls on the front panel,
one for each of the four sound shaping sections (Modulation, Oscillators, Filter, and
Envelope Generators). Each control is surrounded by a ring of 15 LEDs that indicate
approximately the stored or edited value of the current parameter. The parameters
for each section are chosen by pushing the switch for the desired parameter in that
section. That switch then becomes illuminated in amber. Only one parameter can be
activated at a time for editing in each section.
Some parameters offer multiple selections (such as the Modulation SOURCE switch,
shown at right). Pressing that switch advances through the six possible Modulation
sources. For the On/Off type switches like GLIDE ON/OFF (above), 1-2 SYNC or
OUTPUT ON/OFF, the switch is illuminated red when the parameter is turned on,
and goes out when the parameter is turned off.
TECH NOTE: The LP’s editing controls are actually analog potentiometers. When
certain key parameters are selected, the analog control signal is switched to control
that parameter directly. This is called RAC™ (Real Analog Control). RAC gives the LP a
responsiveness that can only be achieved with analog control by providing direct access
to the analog control signal path; straight to the synthesizer circuits. In the Stage Edition,
RAC provides responsive analog control for the Osc 1 & 2, Filter Cutoff, Filter Resonance,
EG Amount, Overload and Filter EG Sustain parameters.
