Module A-142-2 contains two envelope controlled VCAs behind a front panel with 8 HP only.

Each of the two sub-units is the combination of a simple AD/ADSR/AR envelope generator and a VCA. The type of envelope can be selected by means of a toggle switch:

• AR: Attack-Release
• ADSR: Attack-Decay-Sustain-Release with the limitation that Decay Time = Release Time and fixed Sustain level (factory setting 50%)

I/O

• LED control (envelope display)
• Attack (A), manual control, range about 500uS up to several minutes
• Decay/Release (D/R), manual control, range about 500uS up to several minutes
• Mode switch (AD, AR, ADSR)
• Audio level control (small control without knob)
• CVT Input (CVT = CV Time)
• CV Ducking input
• Attenuator for CVT (small control without knob)
• Gate Input (min. +5V, max. +12V)
• Manual Gate (momentary switch)
• Audio Input
• Audio Output
• The Envelope Output of version 1 has been cancelled for the benefit of the new CV Duck input. But there is an internal pin header available that has available the envelope signal (0...+10V) and the CV input of the VCA (0...+10V). Ex works the pins are shortened by a jumper but can be used for modifications (envelope output, VCA CV input).
