Knob Values Are
Offsets
Amp Types and
Morph
Knob settings do not change to new values when an amp type is selected. This
is because knob values are not absolute. Instead, they are an offset to the factory
programmed amp type value. For example, if Post-Lo EQ displays a value
of 3.0, then 3dB is added to the amp type internal (preset) value. Of course,
knob settings do change when user settings are loaded.
The Amp submodule within Preflex is actually comprised of two independent
amplifier processors, Amp-A and Amp-B. The amp types to be used are selected
with the Amp Type pull-down menus. The two amp types share the amp
controls.
These two amp types can then be ‘morphed’ to smoothly transform one amp
type into another, creating new sounds never before possible. Morph accomplishes
this task by interpolating between amplifier component values of the A
and B Amp types as the slider is moved. Morph is NOT a blend or crossfade
control.
Morph allows you to continuously shift between two completely different amp
sounds in realtime with full automation. And because the Color and Bent
knobs also control multiple parameters simultaneously (which is essentially a
morph), amazing new dynamically shifting timbres can be realized.
Amp Controls
Amp EQ Groups
Preflex has two groups of Lo, Mid, and Hi equalizer controls. Pre-EQ is before
the amplifier, and Post-EQ is after the amplifier. Both sets of EQ are available
simultaneously.
The actual frequency and bandwidth of a particular EQ knob depends on the
amp type setting. The EQ knob values are offsets relative to the preset amp
type value; they do not display absolute values.
Amp Pre-EQ
Knobs
The Pre-EQ group modifies the tone of the signal before it passes into the
Amp. Note that the EQ knob values are offsets relative to the preset amp type
value; they do not display absolute values.
Pre-EQ Lo Knob
Modifies the low frequency response of the signal before the Amp. This control
is a set to a fixed frequency, but the frequency changes with the amp type.
