Oscillator Editor
The Octopus' Oscillator Editor module is located on the upper-right of the
Front Panel. This module contains the controls for editing each of the
instrument's additive oscillators.
Overview
Each of the Octopus' 8 Oscillators is made up of 32 harmonics. The
amplitude of each harmonic can be edited in the Harmonic Amplitude
Editor. The Oscillator Editor enables you to load and analyse waveforms
however it is important to remember that only the first 32 harmonics present
in the waveform will be used. As such, rich, noisy waveforms may not be
reproduced with 100% accuracy. At first, it may appear that 32 harmonics is
not enough to produce rich waveforms, however one of the key features of
FM synthesis is its ability to produce complex waveforms from simple
source signals. For example, most hardware FM synths only contain sine
wave oscillators.
The Oscillator Editor module contains the following controls: Oscillator
Select, Oscillator Menu, Harmonic Amplitude Editor, Harmonic Phase
Editor, Frequency, Pitch, Amplitude, Phase and Free. There is also a
waveform display that shows the shape of the current Oscillator's
waveform. These controls are described below.
To select on Oscillator, click on one of the Oscillator Select buttons at the
left of the module. The selected Oscillator is then highlighted and the
Oscillator Editor module now displays the settings of the selected Oscillator.
