SUBTRACTOR SYNTHESIZER

100

Introduction

Subtractor is an analog-type polyphonic synthesizer based on subtractive

synthesis, the method used in analog synthesizers. This chapter will go

through all parameters of each section of Subtractor. In addition to the pa-

rameter descriptions, the chapter also includes a few tips and tricks to help

you get the most out of the Subtractor synthesizer.

! It is recommended that you start with default settings (an “Init

Patch”) if you intend to follow the examples in this chapter, unless

otherwise is stated. An Init Patch is created by selecting “Initialize

Patch” from the Edit menu. If you wish to keep the current settings,

save them before initializing.

The Subtractor has the following basic features:

➜ Up to 99 Voice Polyphony.

You can set the number of voices for each Patch.

➜ Dual Filters.

A combination of a multimode filter and a second, linkable, lowpass filter

allows for complex filtering effects. See page 106.

➜ Two Oscillators, each with 32 waveforms.

See page 100.

➜ Frequency Modulation (FM).

See page 104.

➜ Oscillator Phase Offset Modulation.

This is an unique Subtractor feature that generates waveform variations.

See page 103.

➜ Two Low Frequency Oscillators (LFO:s)

See page 112.

➜ Three Envelope Generators.

See page 110.

➜ Extensive Velocity Control.

See page 114.

➜ Extensive CV/Gate Modulation possibilities.

See page 117.

! Loading and saving Patches is described in the chapter “Working

with Patches” in the Basics book.

The Oscillator Section

Subtractor provides two oscillators. Oscillators are the main sound genera-

tors in Subtractor, the other features are used to shape the sound of the os-

cillators. Oscillators generate two basic properties, waveform and pitch

(frequency). The type of waveform the oscillator produces determines the

harmonic content of the sound, which in turn affects the resultant sound qual-

ity (timbre). Selecting a oscillator waveform is usually the starting point when

creating a new Subtractor Patch from scratch.

Oscillator 1 Waveform

Oscillator 1 provides 32 waveforms. The first four are standard waveforms,

and the rest are “special” waveforms, some of which are suitable for emulat-

ing various musical instrument sounds.

✪ It is worth noting here that all waveforms can be radically trans-

formed using Phase offset modulation (see page 103).

➜ To select a waveform, click the spin controls to the right of the

“Waveform” LED display.

The first 4 basic waveforms are shown as standard symbols, and the

special waveforms are numbered 5 - 32.

Here follows a brief description of the Subtractor waveforms:
