Modulator MIDI plug-in envelope in Logic Pro for iPad

On/Off button: Turn the envelope on or off.

Trigger pop-up menu: Determine if the envelope is triggered by the LFO or by incoming MIDI note on messages.

• Single: After all notes have been released, the envelope is re-triggered by the first MIDI note on message it receives.

  Note: This means that legato playing does not reset the envelope, so keep this in mind during performances.

• Multi: The envelope is re-triggered by each received MIDI note on message.

• LFO: The envelope is retriggered when the LFO reaches its (positive) peak value. See Modulator MIDI plug-in LFO.

  Note: The envelope ignores incoming LFO triggers if it is currently completing an envelope pass.

Sync button: Synchronize the envelope with project grid values. This snaps ADSR values to project bars, beats, and so on.

Delay slider and field: Delay the onset of the envelope. Ranges from 0 to 10 seconds.

Attack slider and field: Set the time required to reach the sustain level. Ranges from 0 to 10 seconds.

Hold slider and field: Set the sustain level and duration. Ranges from 0 to 10 seconds.

Release slider and field: Set the time required for the envelope to fall to a value of zero after the sustain phase of the envelope has finished. Ranges from 0 to 10 seconds.

Steps slider and field: Determine the number of steps per envelope pass. By default, the envelope produces a smoothed continuous stream of controller events, but you can use this parameter to create a stepped controller signal that is similar to the output of a Sample and Hold circuit. When you set a manual step rate, the envelope time can be changed without altering the number of steps.

ENV to LFO Rate knob and field: Set the maximum amount of LFO modulation (LFO depth). The LFO rate can be modulated by the Attack, Hold, and Release parameters (see above).

ENV to LFO Amp knob and field: Set the maximum amount of LFO output modulation. This enables you to fade the LFO in or out with the envelope.

Output Level knob: Scale the envelope output level.

ENV To pop-up menu: Choose a continuous controller number, aftertouch, or pitch bend as the envelope output target. You can also learn a plug-in parameter.

Output Offset slider: Set a positive or negative offset in order to tailor the output for the intended target.

MIDI Channel pop-up menu: Choose a MIDI output channel.
