Use the ES1 sub-oscillator in Logic Pro for Mac

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 different 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
