At its core, Contour is a classic ADSR envelope. The module is activated via a gate input. Attack and sustain parameters can be adjusted via dedicated potentiometers. The length of decay and release phases is controlled via a shared knob. - The same concept was used for the Minimoog. Envelope signals are emitted via a normal and an inverted output. LEDs visualize the module’s work. Modern additions include CV inputs for attack and decay / sustain parameters. The circuit’s curve shapes can be crossfaded between linear and exponential characteristic. EON and EOC connectors allow musicians to daisy-chain several Contour modules to form a complex envelope. The connectors emit a trigger signal each time the attack (EON) respectively release phase (EOC) is completed.
