ES1 oscillator waveforms
The table outlines the basic tones of the oscillator waveforms—how they aect your
synthesizer sound.
Waveform Basic tone Comments
Sawtooth Warm and even Useful for strings, pads, bass, and
brass sounds
Triangle Sweet sounding, softer than
sawtooth
Useful for utes, pads
Square Hollow and “woody” sounding Useful for basses, clarinets, and
oboes
Pulse “Nasal” sounding Great for reed instruments, synth
blips, basses
Use the ES1 sub-oscillator
The ES1 sub-oscillator is used to make your sound richer. Its pitch matches the frequency of the
main oscillator. You can choose from the following sub-oscillator waveform options:
•
A square wave that plays one or two octaves below the frequency of the primary oscillator
•
A pulse wave that plays two octaves below the frequency of the primary oscillator
•
Variations of these waveforms, with dierent mixes and phase relationships, resulting in
various sounds
•
White noise, which is useful for creating percussion sounds as well as wind, surf, and rain
sounds
•
OFF, which allows you to disable the sub-oscillator
•
EXT, which allows you to run an external channel strip signal through the ES1 synthesizer
engine, by using a side chain
Process a channel strip signal through the ES1 synthesizer engine
1 Set the Sub knob to EXT.
2 Choose the side-chain source channel strip from the Side Chain pop-up menu in the upper-right
corner of ES1.
