Module A-140-2 contains two ADSR type envelope generators behind a front panel with 8 HP only.

Each ADSR provides these controls and in/outputs:

• LED (displays the envelope output) 
• A: manual Attack control
• D: manual Decay control
• S: manual Sustain control
• R: manual Release control
• Gate Input
• Retrigger Input
• CVT Input with attenuator (CVT = CV Time)
• Envelope Output 1
• Envelope Output 2

By means of internal jumpers one can select which parameter(s) are controlled by the CVT input (e.g. D only or D+R or A+D+R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question). By means of another jumpers output 2 can be set to normal or inverted envelope. Two more jumpers are used for the optional bus access to the gate signal of the bus for each ADSR.

The output voltage range for each envelope is 0 - 10V.
