After Late Audio Peaks, $119!

The After Later Audio Peaks is a versatile Eurorack module that is a reimagined version of the original Peaks module by Mutable Instruments. This multifunction module offers various envelope generators, LFOs, and drum sounds, making it an essential tool for any modular synthesizer setup. Known for its flexibility and high-quality design, the After Later Audio Peaks module provides musicians and sound designers with a wide range of modulation and sound generation capabilities.

Key Features:

Multifunction Capabilities:

  • Envelope Generator: The Peaks module can function as a dual ADSR (Attack, Decay, Sustain, Release) envelope generator, providing dynamic control over the amplitude and modulation of your sounds.
  • LFO (Low-Frequency Oscillator): Offers multiple LFO shapes and modes, including sine, triangle, square, and random waveforms, for modulating various parameters within your system.
  • Drum Mode: Includes a selection of drum sounds such as bass drum, snare, and hi-hat, allowing you to create rhythmic elements directly from the module.

Dual Channel Design:

  • Independent Channels: The Peaks module features two independent channels that can be configured separately, providing greater flexibility and control.
  • Linked Mode: Channels can be linked for synchronized modulation and effects, useful for creating complex and evolving soundscapes.

User Interface and Control:

  • Knobs and Buttons: Intuitive interface with dedicated knobs and buttons for easy parameter adjustment and mode selection.
  • LED Indicators: Visual feedback through LED indicators for each channel, helping you monitor the status and activity of the module.

Modulation and Connectivity:

  • CV Inputs: Control Voltage (CV) inputs for external modulation of parameters such as attack, decay, and LFO rate.
  • Trigger Inputs: Trigger inputs for each channel, allowing external signals to trigger envelopes or drum sounds.
  • Audio Outputs: Dual outputs for routing the generated sounds and modulated signals to other modules within your system.

Sound Characteristics:

  • Dynamic Modulation: Capable of producing a wide range of modulation shapes and envelopes, from smooth and subtle to sharp and percussive.
  • Versatile Sound Generation: Drum mode provides high-quality percussion sounds, adding rhythmic elements to your modular setup.
  • Complex Textures: When used as an LFO, Peaks can create complex modulations and evolving textures, enhancing your overall sound design capabilities.


  • Modulation Source: Ideal for use as an envelope generator or LFO, providing dynamic modulation for filters, oscillators, and other modules.
  • Percussion: Great for creating drum sounds and rhythmic patterns directly within your modular system.
  • Sound Design: Suitable for sound designers looking to create complex, evolving modulations and textures.

Country of Manufacture:

  • United States: The After Later Audio Peaks module is designed and manufactured in the USA, ensuring high-quality craftsmanship and reliability.
