ES2 global parameters in Logic Pro for iPad
The global parameters affect the overall ES2 sound and behavior.
Global parameters
Tune knob and field: Set the overall instrument pitch in cents. 100 cents equals a semitone step. At a value of 0 c (zero cents), the central A key is tuned to 440 Hz, or concert pitch.
Glide knob and field: Set the time it takes for the pitch of a played note to slide to the pitch of the following played note. See Set the ES2 glide time.
Osc Start buttons: The oscillators can run freely or can begin at the same phase position of their respective waveform cycles each time a note is struck. Tap a button to change the waveform phase start position behavior.
Free: The initial oscillator phase start point is random for each played note. This adds life to the sound. The downside is that the output level may differ each time a note is played, making the attack phase sound less punchy—even if the performance is identical each time—such as when the note is triggered by a MIDI region. This setting is useful when emulating sounds typical of hardware analog synthesizers.
Soft: The initial oscillator phase starts at a zero crossing for each played note. This mimics the sonic character (and precision) typical of digital synthesizers.
Hard: The initial oscillator phase starts at the highest level in the waveform cycle for each played note. The extra punch that this setting can provide is audible only if the Envelope 3 Attack Time parameter is set to a low value—a very fast attack, in other words. This setting is highly recommended for electronic percussion and hard basses.
Voices knob and field: Set the maximum number of notes that can be played simultaneously.
Unison button: Turn unison mode on or off. See Use unison and voices.
Analog knob and field: Rotate to randomly alter the pitch of each note and the filter cutoff frequency. See Detune analog oscillators in ES2.
CBD knob and field: Detuned oscillators periodically beat against each other at a certain frequency. Use CBD to set the beating frequency between low and high notes or to retain a constant beating.
Keyboard Mode buttons: Switch ES2 between polyphonic, monophonic, and legato behaviors. See Set the ES2 keyboard mode.
Bend Up/Dn sliders and fields: Define the upward and downward pitch bend range. See Set the ES2 pitch bend range.
