Analogue Systems RS-60 ADSR (Dual Bus)


Flexible ADSR envelope with voltage control of decay and release times. Interesting hold and repeat functions turn the envelope into a LFO with gating functions. Among the ADSRs the RS-60 module is the most versatile and really recommendable!
Thanks to a new dual-bus concept, this circuit is fully compatible to Doepfer’s Eurorack standard.



Classic ADSR type envelope generator. Decay and release times can be voltage controlled via a common input for positive CVs between 0 and +10V. Time ranges of the segments: Attack: 0,5mS to 10S; Decay: 2,5mS to 20S; Release: 2,5mS to 20S.

Two switches affect the behaviour of the RS-60 in nine different ways:

  • STD/STD: Normal ADSR mode. A gate triggers and holds the envelope up to the release phase.
  • HOLD/STD: hold will hold the envelope at sustain level. Signals in the gate input have no effect. A signal at the Trig/Retrig-In restarts the AD phase and keeps the envelope at sustain level until the next trigger.
  • ONESHOT/STD: Press the swithc into oneshot position and you´ll fire the envelope once. trigger signals at the Trig-Retrig-In will restart th envelope only when oneshot switch is pressed.
  • HOLD / GATED REPEAT and HOLD / AUTO REPEAT have the same effect. Attack and decay phases will be repeated and the module acts as a LFO. Rate is dependent on the A/D times and range from 0.003Hz to 300Hz. A gate at the Trig-Retrig-In holds the signal at +10V, without gate the LFO continues cycling.
  • STD / GATED REPEAT: The envelope will onbly be looped when a gate signal is present at the Gate-Trig-in
  • STD / AUTO REPEAT: A gate at the Trig-Retrig-In holds the signal at +10V, without gate the LFO continues cycling.
  • ONE SHOT / GATED REPEAT and ONE SHOT / AUTO REPEAT have the same effect. the oneshot switch generates a gate and fires the envelope. A gate at the Gate-Trig-in will hold the envelope at +10V, without gate the envelope will be looped.

The envelope signal is present at two outputs A and B and it´s level can be controlled and inverted with a potentiometer.

Similar to MakeNoise´s Maths you can influence the curve of the envelope by feedbacking it: connect the positive output with the CV input for decay/release; the stronger the modulation the shorter, more exponential and punchy the envelope gets.


The Dual Bus version of the RS-60 features two power connectors, meaning it can be directly connected to either an Analog Systems or a Doepfer modular system. – Adapters are no longer necessary.

Because of the different position of the mounting holes there will be a gap of 0.5HP (= 2.5 mm) when mounting an Analogue Systems module next to a Eurorack module. Take this into consideration when planning your system. Gaps can be covered with 1.5HP wide blank panels by Doepfer.
