Adds special-purpose controls for envelopes generated by Stage, Booster Stage, and Hostage modules.

Combine Stage, Booster Stage, Hostage, and Upstage modules to generate complex envelopes with any number of stages.

Use an Upstage module to:

• Set the starting voltage for an envelope.
• Manually trigger an envelope.
• Configure an envelope that automatically retriggers when it completes.
• Suppress incoming triggers while an envelope is in progress.

Controls

• LEVEL: The voltage sent to the OUT output.

  The polarity switch (UNI / BI) selects the range of the LEVEL knob: Either unipolar control voltage (0 to 10V) or bipolar control voltage (-5 to 5V).

• WAIT button: Suppresses triggers from both the TRIG input and the TRIG button.

• TRIG button: While pressed, offers 10V to the TRIG output. While not pressed, offers 0V.

  This button is ignored if the WAIT gate signal is high or the WAIT button is pressed.

Ports

• WAIT: A gate signal that, when high, suppresses incoming triggers from both the TRIG input and the TRIG button.

• TRIG (input): The incoming trigger signal offered to the TRIG output.

  This signal is ignored if the WAIT gate signal is high or the WAIT button is pressed.

• TRIG (output): Emits either the TRIG input signal or the TRIG button voltage, whichever is greater.

  If the WAIT gate signal is high or the WAIT button is pressed, this output emits 0V regardless of the value of TRIG signal and the TRIG button.

• OUT: Sends the voltage set by the (CV-modulated) LEVEL knob.

• CV: A control voltage signal to modulate the LEVEL parameter.
