Sculpture control sources include two envelopes. In traditional synthesizer designs, envelopes are used to control amplitude and filter levels over time. By comparison, Sculpture envelopes are somewhat special in that they can be used as:
Traditional four-segment envelopes
MIDI controller modulations
A combination of both—as MIDI controller movement recorders with ADSR-like macro parameters, for polyphonic playback
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 Sculpture envelope display and Sculpture active envelope parameters.
