Synthrotek - Quadrangle

Overview

A specialist for complex modulations – Quadrangle is composed of four envelopes with AD, AR and loop mode.  All attack and decay respectively release parameters can not only be adjusted via knobs, but are voltage controllable as well. Fast attack times lead to a snappy, percussive behavior. While in loop mode, the envelopes can go up into the audio range. Bipolar attenuators allow users to level and / or invert CV signals generated by the circuits. Via trigger outputs, it is possible to daisy-chain several channels to form a multistage envelope or a complex LFO.

Details

Each of the Quadrangle’s four envelopes comes equipped with the following connectors and control elements:

  • Gate input
  • Switch for choosing between AD, AR and loop mode
  • Attack and decay / release potentiometers
  • Attack and decay / release CV inputs
  • Trigger outputs, which emit a signal at the end of attack (EOA) and decay respectively release phase (EOC).
  • Bipolar attenuator
  • Signal output

The EOC outputs are normalized to the gate input of the subsequent channel. A switch decides whether the fourth EOC output triggers the first envelope or not. All A and All D/R connectors allow users to modulate all attack or decay / release parameters equally. A bipolar sum connector emits a mix of all CV signals generated by the Quadrangle.
