Control envelope parameters
• Envelope 1/2 buttons: Choose control envelope 1 or 2, and access the parameters of each.
• On/Off buttons (1 and 2): Turn the control envelope 1 and 2 modulation sources on or off.
• Target pop-up menus: Choose modulation targets 1 and 2. Two targets can be assigned
per envelope, with an optional via modulation. Targets include string, object, pickup,
Waveshaper, and filter parameters.
• Via source pop-up menus: Choose the modulation source used to scale the amount of
envelope modulation.
• Amt and Via amount sliders: Set the modulation amount. In cases where any via source
other than “off” is selected, both sliders are available for use.
• Amt slider: Set the modulation amount when the incoming via signal is 0, such as
when the modulation wheel is at its minimum position, for example.
• Via amount slider: Set the modulation amount when the incoming via signal is at full
level, such as when the modulation wheel is at its maximum position, for example.
• VariMod source pop-up menu: Choose a modulation source. (VariMod is available only
for recorded envelopes.)
• VariMod slider: Set the amount of envelope variation.
• Ctrl/Env mode buttons: Select either controller (run mode) or standard envelope
behavior. If both are activated, the controller value is added to the envelope output,
resulting in a modulation offset.
Note: When the envelopes are used as polyphonic modulation recorders and playback
units, each voice is handled independently, with a separate envelope being triggered as
each note is played.
• Envelope display: Shows the envelope curve, and allows you to record and edit
envelopes. See Logic Pro Sculpture envelope display and Use Logic Pro Sculpture active
envelope controls.

The following parameters are active only if the envelope is engaged (Mode buttons set to
either Env or Ctrl+Env).
Envelope parameters
• A-Time Velosens slider: Set velocity sensitivity for the attack phase of the envelope.
Positive values reduce the attack time at lower velocities. Negative values reduce the
attack time at higher velocities.
• Timescale field: Scale the duration of the entire envelope between 10% (ten times
faster) and 1000% (ten times slower). This also affects the appearance of the envelope
curve displayed as it is shortened (sped up) or lengthened (slowed down).
• Sustain mode pop-up menu: Choose the behavior of the envelope while a note is held.
Choices are Sustain mode (default), Finish mode, and three loop modes—Loop Forward,
Loop Backward, and Loop Alternate. See Loop Logic Pro Sculpture envelopes.
