The Pittsburgh Modular Envelope is a multi-stage transient generator with voltage controllable rise and fall stages. Using the sustain switch to toggle between modes, the Envelope can function as either a 2 stage attack-decay envelope or a 3 stage attack-sustain-release envelope.
The Envelope response for rise and fall is continually adjustable between logarithmic, linear, and exponential allowing for dynamic and precise envelope shaping. Cycle times range from .8ms or 1250Hz at the longest.
This module is incredibly versatile. It can perform as a
- Voltage Controlled Envelope Generator
- Voltage Controlled Slewing (Portamento)
- Envelope Follower
- VCO and Voltage Controlled LFO
- VC pulse delay
- VC wave shaper
