Description

Unlock the full potential of your modular synthesizer setup with the 4ms PEG: Pingable Envelope Generator. This innovative Eurorack module offers a unique approach to envelope generation, allowing you to create complex rhythmic patterns and nuanced dynamics with ease. The PEG features dual envelope channels that can be independently synced to a tap tempo or an incoming pulse clock, making it perfect for live performances and intricate studio compositions.

Each envelope is equipped with a time divider/multiplier, giving you the freedom to offset them from the main clock by factors ranging from 1/8 to 8x the clock time. This flexibility allows for the creation of complex modulation schemes that are sure to inspire your sound design. The module also boasts extensive waveshaping options, allowing you to fully customize the contour of your envelopes with controls for skew, curve, and scale.

For those who love to experiment, the PEG offers a plethora of triggering and cycling options. Dedicated trigger inputs let you set off your envelopes in various ways, while the Skew parameter jack provides a variable phase gate output for synchronized effects. Whether you're aiming for tight rhythmic precision or lush, evolving soundscapes, the 4ms PEG delivers unmatched creative potential.

Key Features:

  • Dual envelope channels with independent ping synchronization
  • Time division/multiplication from 1/8 to 8x the clock time
  • Extensive waveshaping options, including skew, curve, and scale controls
  • Multiple cycling and triggering options for versatile modulation
  • CV control of Ping Div/Mult, Skew, and Curve
  • Unique gate outputs: End-of-Rise, End-of-Fall, and Half-Rise
  • 20 HP Eurorack format, consumes 105 mA (+12 V) / 35 mA (-12 V)

FAQs

How does the 4ms PEG: Pingable Envelope Generator work with clock pulses?

The 4ms PEG uses the time between external clock pulses, or "pings," to set the envelope lengths, allowing precise synchronization with your modular system's tempo.

Can the 4ms PEG be used as an LFO?

Yes, the 4ms PEG can operate in cycle mode, turning each envelope into a low-frequency oscillator (LFO) for modulating other parameters in your modular setup.

What is the HP size and power requirement for the 4ms PEG?

The 4ms PEG is a 20HP Eurorack module that requires ±12V DC at 88mA and ±5V DC at 41mA, necessitating a compatible Eurorack case and power supply.

Is the 4ms PEG suitable for creating complex modulation patterns?

Absolutely, the PEG's dual envelope design and ping synchronization make it ideal for creating intricate modulation patterns in time with your system's clock.

Does the 4ms PEG support both rise and fall envelope stages?

Yes, the PEG features a simple two-stage rise-and-fall envelope design, allowing for flexible modulation shaping.

Reviews

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about 4ms PEG: Pingable Envelope Generator.

Features and functionality

  • The 4ms PEG offers built-in clock multiplication/division, and a single CV "shape" change, enhancing its pingable capabilities.

    Source
  • The PEG measures two clock pulses to determine total envelope time, primarily creating Attack/Decay envelopes.

    Source
  • It's noted that PEG can be limited to decay-only use, providing a different approach to envelope shaping.

    Source

Comparisons

  • The 4ms PEG's envelopes are criticized for feeling digital, contrasting with the more organic feel of Maths' analog envelopes.

    Source
  • While PEG lacks the mixing/attenuation channels of Maths, it compensates with its unique clock features, appealing to those who prioritize pingable functionality.

    Source
  • Falistri and PEG use clockable LFOs with sine shapes, unlike Maths or Rampage, which are mentioned for creating ASR envelopes.

    Source

Use cases and applications

  • PEG is ideal for users seeking a module with built-in clock management, suitable for complex rhythmic patterns.

    Source
  • PEG's design isn't suited for use as a slew limiter for v/oct pitch signals, a limitation compared to other function generators.

    Source

User experience

  • Owners find the PEG engaging for creative experimentation but may prefer Maths for its tactile, analog envelope response.
