ABOUT ANALOGUE SYNTHESIS
All of these three main elements can be controlled by various methods for example:
The “Pitch” of a note can be played on a master keyboard or a synthesiser & additionally it can be manipulated in real time using
the “Pitch Bend Wheel” to create “Slides” & “Bends” in pitch. LFOs ( low frequency oscillators ) can be used to “Wobble” the pitch
of a note at a specific rate creating a “Vibrato” effect. An Envelope Generator can also be used to “Slide” the pitch in an automatic
way.
The Filter can be manipulated by LFOs to vary the “Tone” of a sound at a specific rate creating a “Wah Wah” type of effect. An
Envelope Generator can also be used on the Filter so that the “Tone” of a sound changes over time. A feature called “Keyboard
Tracking” can also be used on the Filter so that the “Tone” of a sound changes depending on the note being played.
The Amplifier can be manipulated by Envelope Generators so that changes in the “Volume” of a sound over time can make the
sound short & percussive, or more like a piano or even like an organ. Additionally the “Velocity” at which you hit the keys can also
be used to manipulate volume making a sound more “expressive”.
The elements that manipulate these three main synthesis elements are called “Modulation Sources”.
The Supernova II Rack features 3 Envelope generators & 2 LFOs ( Low Frequency Oscillators ) as Modulation “Sources”. In addi-
tion to this Velocity, ( The dynamics of your keyboard playing. i.e. ppp to fff ) Aftertouch ( Pressure on the key(s) of the master key-
board while note(s) are held ) & the Modulation Wheel are included in a as additional “Sources” of modulation signals in a
“Modulation Matrix”. This allows almost any “Source” to modulate a given parameter. It is even possible to have combinations of
different “Sources” modulating one parameter. In the Supernova II Rack this has been neatly arranged on the front panel so that
accessing all the possible combinations of modulation is quick & easy. Below is the Modulation Matrix for the Oscillator section.
Oscillator Modulation Matrix
Simply by pressing the desired “Source” ( the row of buttons on the right ) & the desired “Destination” ( the row of buttons on the
left ) & adjusting the “Level” or “Mod Depth” knobs allows the creation of complex modulation setups easily. On older modular
Analogue Synthesisers this was done with “Patch” leads that physically connected the “Sources” & “Destinations” together.
This allows some very powerful performance features to be implemented. i.e. It is possible to sweep the “Sync” effect, “Harden”
effect, Pulse Width Modulation & alter the Mix of all three oscillators independently plus open the Filter Cutoff Frequency, Reduce
the Filter Resonance, add lots more Distortion & Delay & reduce the Chorus & Reverb, all by simply moving the Mod Wheel for-
ward! With the Modulation Matrix relationships like this are quick to set up & will transform a “static” sound into one with real
“hands on” control & flexibility.
This is where most synthesisers end. However, the Supernova II Rack features a very powerful Effects section. It could be said
that effects are as much “part” of a sound as the raw sound itself. Some of the larger old Analogue systems had built in spring
reverb, & with the development of DSP technology, digital effects have become available in modern synthesisers. However when in
a “Multimbral” application, all the sounds are generally passed through one set of effects. In the Supernova II Rack, a block of 7
effects is part of the “Program” & can be considered to be part of the synthesis engine. These include Distortion, EQ, Reverb,
Chorus/Flanger/Phaser, Delay, Panning & Comb Filter effects. These can simulate “Real World” effects like Echo & Room
Reverberation etc. Or they can be used to just do really weird things to your sound! For details on what each effect does & how
best to use them refer to the about Effects section part of this manual on page 18 for details.
The best thing to do is just get in there & tweak those knobs, after all that’s why we put them there! Experiment & you’ll soon be
creating your own sounds. Don’t worry about erasing the factory sounds in the memory. If you want, the factory sounds can be
recalled. To do this Refer to page 46 for details.
