Malekko Heavy Industry Richter Series Eurorack Multi-Function Linear Function Generator Module

The Malekko Heavy Industry Richter series of modules in Eurorack format offer the same great sound, ergonomics, musicality and quality that made the Wiard 300 series legendary at a fraction of the cost and size. The Malekko/Richter Envelator is a eurorack version of the infamous 300 Series Envelator module.

The Envelator is a multi-function linear function generator. The attack and decay slopes are individually voltage controllable with input attenuators. The unit outputs the envelope, inverse of the envelope (negative going envelope), a voltage step signal during the attack phase, and a pulse at the end of the decay phase.

The three-position mode switch determines the function of the envelopes. When set to AR, the envelope will act as an AR envelope, maintaining full level until GATE (in) goes 'low.' In AD mode, the envelope acts as an AD envelope and will begin decay as soon as the attack stage is complete. In Cycle mode, the end pulse is fed back to the envelope input and will force the envelope to re-trigger. In this mode, the Envelator output functions as a shaped triangle waveform LFO. When in Cycle mode, the SQR output acts as a square wave LFO with the pulse width determined by the settings of the A and D controls.

  • Module controls
    • AD/AR/CY switch: selects among AR, AD and Cycle modes
    • ATTACK knob: sets time for attack phase
    • DECAY knob: sets time for decay phase
    • DELAY knob: sets time for delay phase
    • AMOD knob: attenuator for AMOD attack modulation CV input
    • DMOD knob: attenuator for DMOD decay modulation CV input
    • x10 button: multiplies attack and decay times by a factor of ten
    • DELAY button: in Cycle mode, engages delay phase before envelope repeats
  • Patch points
    • DEL CV input: CV control over delay time with no attenuation
    • GATE input: gate trigger input
    • SQR output: outputs +10 volts during attack phase, 0 volt during decay phase
    • -OUT output: negative control output, inverted copy of envelope
    • END output: outputs pulse at end of decay phase
    • +OUT outputs: main control outputs, two positive copies of envelope
    • AMOD input: attack modulation CV input, attenuated by AMOD knob
    • DMOD input: decay modulation CV input, attenuated by DMOD knob
