Pittsburgh Modular Envelope

Multifunction Envelope Generator
The Pittsburgh Modular Envelope is a complex multi-stage envelope generator with voltage controllable attack and decay/release. Using the sustain switch to toggle between modes, the Envelope functions as either a 2 stage attack-decay envelope or a 3 stage attack-sustain-release envelope.

The Envelope response for attack and decay/release is continually adjustable between logarithmic, linear, and exponential allowing for precision envelope shaping. Cycle times range from .8ms or 1250Hz at the shortest to at the longest.
This module is incredibly versatile. It can perform as voltage controlled envelope generator, voltage controlled portamento, envelope follower, VCO, and voltage controlled LFO, pulse delay, and wave shaper.

ENVELOPE CONTROLS:

LINEAR ATTACK / NON-LINEAR ATTACK SWITCH
Determines the response type of the attack portion of the envelope. Set to linear, the response is always linear. Set to non-linear, the response is assigned using the attack NON-LINEARITY/CV IN attenuator. Full left offers a logarithmic response, setting the knob to 12 o'clock provides a linear response, and turning the knob full right results in an exponential response.

ATTACK CONTROL KNOB
Adjusts the attack time of the envelope.

ATTACK NON-LINEARITY/CV IN ATTENUVERTER
Multifunction attenuverter used to attenuvert incoming attack CV. Turning the knob left of 12 o'clock results in attenuated inverted CV. At 12 o'clock, the CV response is off. Turning the knob to the right of 12 o'clock results in attenuated CV.

SUSTAIN ON/OFF SWITCH
Changes the envelope response. Set to off (left), the envelopes functions as an attack-decay envelope generator. Set to on (right), the envelope functions as an attack-sustain-release envelope generator.

LINEAR DECAY/RELEASE / NON-LINEAR DECAY/RELEASE SWITCH
Determines the response type of the decay/release portion of the envelope. Set to linear, the response is always linear. Set to non-linear, the response is assigned using the decay/release NON-LINEARITY/CV IN attenuator. Full left offers a logarithmic response, setting the knob to 12 o'clock provides a linear response, and turning the knob full right results in an exponential response.

DECAY/RELEASE CONTROL KNOB
Adjusts the decay/release time of the envelope.

NON-LINEARITY/CV IN ATTENUVERTER
Multifunction attenuverter used to attenuvert incoming decay/release CV. Turning the knob left of 12 o'clock results in attenuated inverted CV. At 12 o'clock, the CV response is off. Turning the knob to the right of 12 o'clock results in attenuated CV.

CYCLE ON/OFF SWITCH
Set to on (up), the envelope will retrigger the attack stage at the end of the decay/release stage causing the Envelope module to cycle.

ENVELOPE PATCH POINTS:
  • RISE CV IN - Attack CV input.
  • BOTH CV IN - Attack and decay/release CV input.
  • FALL CV IN - Decay/release CV input.
  • SIGNAL INPUT - Main signal input.
  • END OF ATTACK OUT - Gate signal output. Signal goes high at end of attack stage.
  • TRIGGER OUT - Trigger output. Trigger created at end of decay/release stage.
  • SIGNAL OUT - Main signal output.
