LinPlug Octopus - Manual (Page 56)

To make the sound more interesting, we'll now change the spectrum of the
Oscillator. This can be done in two ways: statically using the Harmonic
Amplitude Editor in the Oscillator Editor section (this produces a fixed
change in the waveform shape), or using Frequency Modulation in the
Oscillator Matrix section (this produces a dynamic change in the
waveform's shape).
5. Move the mouse to the Harmonic Amplitude Editor. The amplitude
of each of the waveform's 32 harmonics can be set by clicking and
dragging in the Editor. The results of the editing are displayed in the
Waveform display to the right of the editor.
