The Extended ADSR is a complex envelope generator that not only uses the four segment envelope normally encountered in synthesizers, but is designed with extra features such as an initial voltage controllable delay time, voltage control of each segment, switchable slope forms, and a master voltage control. Each segment may be manually set and voltage controlled. In addition to the normal Attach, Decay, Sustain, and Release segments, an Initial Delay time is included. A master 1V/OCT inout allows to control all slope times for effects such as decreasing the entire envelope time as the pitch of an associated oscillator increases - a phenomenon is typical of many acoustic instruments. The Equal Power Stereo Mixer / Panner by Random*Source is designed to emulate the behavior of the famous Serge VCAs. It uses some of the best audio components available today including THAT2180 VCA chips. Version 1.1 contains a number of additions and improvements that were adopted in surface mounted technology (SMT): Balanced Outputs, using „a new generation of monolithic audio differential line drivers offering improved performance over conventional crosscoupled designs“ for low noise and distortion. These outputs can be connected to balanced or unbalanced equipment (amplifiers, A/D converters...) Burr-Brown op-amps in the audio path. Optimized value set and easier calibration / setup. The R*S Stereo-Mixer has two independent channels for stereo panning and provides level control (or enveloping) as well as voltage controlled panning. Two Aux inputs allow to mix in other signals (not affected by control voltages or knobs) and to chain mixers. The output is available at a pair of banana jacks as well as (6.35mm / 1/4") TRS jacks (phone connectors) for connecting to external amplifiers, ADCs etc.
