Table Of Contents
Amplifier parameters: The area at the top right contains the output parameters, where
you can set the overall volume of the ES2, and add a sine signal at the output stage.
See Using the ES2 Amplifier Parameters.
Modulation router or Vector Envelope: The dark strip across the center of the ES2 interface
is shared by the modulation router and the Vector Envelope. You can use the buttons
at the right end of this section to switch between the two.
The router links modulation sources, such as the envelopes and other parameters
shown in the lower portion of the interface, to modulation targets, such as the
oscillators and filters. See Getting to Know the ES2’s Modulation Router.
The Vector Envelope is an extremely flexible and powerful envelope generator, which
provides extensive control over your sound. See Getting to Know the ES2’s Vector
Envelope.
Modulation controls and parameters: The area immediately below the router is where
you can assign and adjust the modulation generator parameters (such as LFO and
envelope parameters). See Working with Modulation in the ES2.
Planar Pad: The square area at the top right is a two-dimensional controller known as
the Planar Pad—which facilitates the simultaneous manipulation of two, freely
assignable, parameters. The Planar Pad can be controlled using the mouse, another
controller, or the Vector Envelope. See Using the ES2’s Planar Pad.
Effect section: The built-in effect processing options are found to the right of the Output
parameters. See Using the ES2’s Integrated Effect Processing Section.
Random parameters: Used to randomize sound parameters, the Random parameters
are found below the circular Filter area. See Creating Random ES2 Sound Variations.
Macro and MIDI controller parameters: The area located on the thin, gray strip at the
bottom can display either Macro parameters or MIDI controller assignments. The
preassigned macro sound parameters are perfect for quick tweaks to the ES2’s sound
(and that of ES2-based GarageBand instruments). You can reassign MIDI control numbers
for these parameters if desired. See Using the ES2 Macro Control Parameters.
Using the ES2 Oscillators
The synthesizer oscillators are used to generate one or more waveforms. This signal is
then sent to other portions of the synthesizer engine for shaping, processing, or
manipulation.
Before the parameters are discussed, a few of the special features available to you in the
ES2 oscillator section should be mentioned.
Oscillators 2 and 3 are almost identical to each other, but they differ from Oscillator 1.
Oscillator 1 can be frequency modulated by Oscillator 2, for FM synthesis sounds.
