Introduction
This chapter contains descriptions of the included VST in-
struments and their parameters.
ÖMost 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:...

To hear the signal generated by the oscillator(s), the 
corresponding Osc dial in the oscillator sections must be 
turned clockwise to a suitable value.
OSC 1 parameters
Oscillator 1 acts as a master oscillator. It determines the 
base pitch for all three oscillators. Oscillator 1 features the 
following parameters:Triangle The Triangle waveform generates only a few harmonics, 
spaced at odd harmonic numbers, which produces a 
slightly hollow sound.
Sine The sine wave is...

OSC 2 parameters
Oscillator 2 has the following parameters:
OSC 3 parameters
Oscillator 3 has the following parameters:
Parameter Value Description
Osc 2 0–100 This controls the output level of the oscil-
lator. 
Coarse +/- 48 
semitonesThis determines the coarse pitch for Osc 
2. If FM is enabled, this determines fre-
quency ratio of the oscillator regarding 
Osc 1.
Fine +/- 50 cent Fine tunes the oscillator pitch in cent in-
crements (100th of a semitone). If FM is...

About frequency modulation
Frequency modulation or FM means that the frequency of 
one oscillator (called the carrier) is modulated by the fre-
quency of another oscillator (called the modulator).
In Prologue, Osc 1 is the modulator, and Osc 2 and 3 
are carriers.
Osc 2 could be said to be both carrier and modulator as if Freq Mod is 
applied to Osc 2 it is modulated by Osc 3. If Osc 2 also uses frequency 
modulation, Osc 3 will be modulated by both Osc 1 and Osc 2.

Filter section
The circle in the middle contains the filter parameters. The 
central dial sets the filter cut off parameter and the outer 
ring the filter type:
About the filter types
You select which filter type to use using the buttons 
around the filter cut off knob. The following filter types are 
available (listed clockwise from 9 o’clock):
Master Volume and Pan
The master Volume controls the master volume (ampli-
tude) of the instrument. By default this parameter is...

Modulation and controllers
The lower half of the control panel displays the various 
modulation and controller assignment pages available as 
well as the effect page. You switch between these pages 
using the buttons below the Filter section.
The following pages are available:
The LFO page has two low frequency oscillators (LFOs) 
for modulating parameters – see below.
The Envelope page contains the four Envelope genera-
tors which can be assigned to control parameters –...

Assigning LFO modulation destinations
To assign a modulation destination for a LFO, proceed as 
follows:
1.Click in the “Mod Dest” box for one of the LFOs.
A pop-up appears with all possible modulation destinations are shown. 
All Sound parameters as well as most LFO and Envelope parameters are 
available as destinations.
The modulation destination pop-up.
2.Select a destination, e.g. Filter Cut Off.
The selected modulation destination is now shown in the list. Beside the...

You switch between the four envelopes in the section to 
the left.
Clicking on either of the four mini curve displays 1 to 4 will select it and 
display the corresponding envelope parameters to the right. The mini 
curve displays also reflect the envelope settings for each corresponding 
envelope.
Envelope generators have four parameters; Attack, De-
cay, Sustain and Release (ADSR).
See below for a description of these.
You can set envelope parameters in two ways; either...

Assigning Envelope velocity destinations
You can also assign Envelope modulation that is velocity 
controlled (i.e. governed by how hard or soft you strike a 
key). This is done as follows:
1.Click in the “Vel Dest” box for one of the envelopes.
A pop-up appears with all possible velocity destinations are shown. 
2.Select a destination. 
The selected velocity destination is now shown in the list. Beside the 
destination, a default value (50) has been set. The value...
