ES1 oscillator parameters in Logic Pro for iPad
ES1 includes a primary oscillator and a sub-oscillator. The primary oscillator generates a waveform that is sent to other parts of the synthesizer for processing or manipulation. The sub-oscillator generates a secondary waveform one or two octaves below that of the primary oscillator, making your sound richer.
Oscillator parameters
Waveform knob: Select the waveform of the primary oscillator, which is responsible for the basic color of the tone. See ES1 oscillator waveforms.
Tune knob and field: Tune the instrument in cents. One cent is 1/100th of a semitone.
32’, 16’, 8’, 4’, and 2’ buttons: Transpose the pitch of the oscillators up or down by octaves. The lowest setting is 32 feet and the highest is 2 feet. The use of the term feet to determine octaves comes from the measurements of organ pipe lengths. The longer and wider the pipe, the deeper the tone.
Sub Osc Wave knob: Generate square, pulse, and white-noise waveforms with the sub-oscillator. The sub-oscillator 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
Off, which allows you to disable the sub-oscillator
Noise, which is useful for creating percussion sounds as well as wind, surf, and rain sounds
External, which allows you to run an external channel strip signal through the ES1 synthesizer engine, by using a side chain
Osc Mix slider and field: Set the level relationship between the primary and sub-oscillator signals. When the sub-oscillator is switched off, its output is completely removed from the signal path.
Change ES1 pulse width
In Logic Pro, rotate the Waveform knob. The pulse width of the waveform is displayed as a percentage.
The pulse width can also be automatically controlled with modulators (see ES1 modulation parameters). Modulating the pulse width with a slowly cycling LFO, for example, allows periodically mutating, fat bass sounds.
Process a channel strip signal through the ES1 synthesizer engine
In Logic Pro, set the Sub Osc Wave knob to External.
Choose the side chain source channel strip from the Side Chain pop-up menu in the upper-right corner of ES1.
