M 511 D

Dual Envelope Generator

The DUAL ENVELOPE GENERATOR module in typical ADSR-Style. 

Time ranges from 1 ms to approx. 20 seconds. Gate button for manual triggering (both envelopes). 

LEDs for ’gate pulse present‘ and for each stage of the envelope. “Normal” and “Retrig” Mode.

M 511 C

Voltage Controlled 

Envelope Generator

The VOLTAGE CONTROLLED ENVELOPE GENERATOR in typical ADSR-Style with five voltage controlled parameters with associated attenuator knobs: attack time, decay time, sustain level, release time and envelope amplitude. The input jack for the amount of contour control is internally connected to +10 volt. 

The time parameters range from 1 ms to approx. 20 s (at full modulation). The time control voltage inputs are daisy chained. Control range is 0-10 v. Two LEDs serve as indicator lamps for ’gate pulse present‘ and for the envelope output.

M 511 AC

Quad Voltage Cotrolled Gate Delay

The QUAD GATE DELAY combines four voltage controlled gate delay circuits in one module, which delay the incoming gate signals in a range from ca. 1 ms up to 20 seconds. Each delay unit hat its own pair of display LEDs. 

The four gate in/outputs are internally connected like this: Output 1 goes into input 2, output 2 goes into input 3 and output 3 goes into input 4. The ‘Manual Gate’ button affects delay input 1. The time control voltage inputs are daisy chained. Input 1 is internally connected to +10 volts.
