Creating Sounds; Oscillator Section - Roland S-1 Owner's Manual

Creating sounds

Creating sounds
The S-1 features a number of functions you can use to create sounds. The tones you create are saved to each pattern.
The performance data and tones from the factory settings (presets) are saved in patterns 1-01 through 1-16.
When you want to create a sound from scratch, we recommend that you either select an empty pattern from 2-01 onward, or
initialize a pattern.

OSCILLATOR section
The OSCILLATOR section features an oscillator (hereafter "OSC") with variable pitch (frequency). The OSC generates the basic
waveform used as the sound source for the synthesizer.

Waveform characteristics
Sawtooth waves are composed of a fundamental sine wave
and the sine waves of the integer harmonics, all at a fixed ratio.
The way that these waves are structured is shown at the graph
at right. The wave includes the nth harmonic at a volume of
1/n, with the fundamental wave considered as "1".
Square waves are composed of a fundamental sine wave and
the sine waves of the odd-numbered harmonics, all at a fixed
ratio.
For the nth harmonic, the sine waves are included at a ratio of
1/n, the same as for the sawtooth wave.
However, the even-numbered harmonics are left out entirely.
