A-140-2

Dual Micro ADSR

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:

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

By means of internal jumpers one can select which parameters 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.
