The included VST Instruments
Introduction
This chapter contains descriptions of the included VST in-
struments and their parameters.
Ö Most of the included instruments are compatible with
VST3, this is indicated by an icon in front of the name (for
further information, see the section “About VST 3” in the
chapter “Audio Effects” in the Operation Manual).
Prologue
Prologue is modelled on subtractive synthesis, the method
used in classic analog synthesizers. It has the following ba-
sic features:
• Multimode filter
Variable slope lowpass and hipass, plus bandpass and notch filter
modes – see “About the filter types” on page 51.
• Three oscillators, each with 4 standard waveforms plus
an assortment of specialized waveforms.
See “Selecting Waveforms” on page 47.
• Frequency modulation.
See “About frequency modulation” on page 49.
• Ring Modulation.
See “Ring modulation” on page 50.
• Built-in effects.
See “Effects (EFX) page” on page 55.
• Prologue receives MIDI in Omni mode (on all MIDI
channels).
You don’t need to select a MIDI channel to direct MIDI to the Prologue.
Ö The signal flow of the Prologue synth is illustrated in
the section “Diagrams” on page 86.
Sound parameters
Oscillator section
This section contains parameters affecting the 3 oscillators.
These are located in upper half of the instrument panel.
Selecting Waveforms
Each oscillator has a number of waveforms which are se-
lectable by clicking on the waveform name in the box lo-
cated in each oscillator section.
Selecting waveforms.
The following waveforms are available:
Waveform Description
Sawtooth This waveform contains all harmonics and produces a
bright and rich sound.
Parabolic This could be described as a “rounded” sawtooth wave-
form, producing a softer timbre.
Square Square waveforms only contain odd number harmonics,
which produces a distinct, hollow sound.
