Specifying The Waveform And Pitch (Osc); Osc 1 (Oscillator 1) Button/Osc 2 (Oscillator 2) Button; Wave Buttons - Roland SH-201 Owner's Manual

Creating sounds

Specifying the waveform and pitch (OSC)

The OSC (oscillator) section produces the waveform that is the basis of the sound.
Selecting a waveform will also determine the pitch.
The SH-201 has two oscillators; OSC 1 and OSC 2.
You can use these separately, or together to create rich or complex sounds.
For details on how you can combine the two oscillators, refer to Combining waveforms to create rich or
metallic sounds (MIX/MOD) (p. 32).

OSC 1 (oscillator 1) button/OSC 2 (oscillator 2) button

fig.OSC-buttons
Use these buttons to specify whether you're making settings for OSC 1 or OSC 2.
Press the button for the desired oscillator; it will light.

WAVE buttons

fig.WAVE-buttons
Use these buttons to select the waveform that is the basis of the sound. One of the indicators will light to indicate
the waveform that's selected. Press the right button to move clockwise through the selections, or the left button
to move counterclockwise.

Description
This waveform contains the fundamental frequency (sine wave) plus all of its integer mul-
tiples (overtones) at a fixed proportion.
This waveform contains the fundamental frequency (sine wave) plus its odd-numbered in-
teger multiples (overtones) at a fixed proportion.
The overtone structure will change significantly depending on the width of the upper por-
tion (pulse width, p. 30) of the waveform.
This waveform contains the fundamental frequency (sine wave) plus its even-numbered in-
teger multiples (overtones) at a fixed proportion.
A waveform with no overtones (harmonics). It consists of only one single frequency.
A waveform containing all frequencies. Use this for percussion sounds or sound effects.
Produces a tone containing high overtones, similar to feedback on a guitar. Ideal for creat-
ing aggressive, cutting sounds.
A sound resembling seven sawtooth waves played simultaneously. Pitch-shifted sounds
are added to a core sound. Ideal for creating string sounds and other rich tones.
This plays the sound from the audio source connected to the rear panel INPUT jacks. Refer
to p. 52.
* There will be no sound if nothing is connected to the INPUT jacks or if you have turned
down the volume of the connected source or the INPUT VOL (p. 49).
