• Planar Pad: The square area at the top right is a two-dimensional controller known
as the Planar Pad. The Planar Pad facilitates the simultaneous manipulation of two
assignable parameters, and can be controlled with the mouse, another controller, or the
Vector Envelope. See Use the Logic Pro ES2 Planar Pad.
• Effect section: The built-in effect-processing options are found to the right of the
output parameters. See Logic Pro ES2 integrated effects processor.
• Macro and MIDI controller parameters: The area shown 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 sound (and
that of ES2-based GarageBand instruments). You can reassign MIDI control numbers for
these parameters. See Logic Pro ES2 macros and controllers overview.

Logic Pro ES2 oscillator parameters overview
ES2 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.
• 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.
• Oscillators 2 and 3 can be synchronized to, or ring modulated with, oscillator1. They
also have rectangular waves with either user-defined fixed pulse widths or pulse width
modulation (PWM) features.
• You can use the modulation router to simultaneously change the pulse widths of
rectangular waves generated by oscillator1 and the synchronized and ring-modulated
rectangular waves of oscillators2 and 3.
