Description

The 4ms Stereo Triggered Sampler is an essential addition to any Eurorack enthusiast's setup, offering a high-fidelity two-channel stereo sampling experience. This versatile module allows you to record stereo WAV files directly onto a microSD card, supporting up to 600 stereo files per channel, with sampling rates up to 32 Bit / 96kHz. Ideal for live performance or studio use, the STS enables instantaneous playback and creative manipulation of samples, from pitch shifting to reversing, all with the flick of a switch or turn of a knob.

Each channel is equipped with intuitive controls for pitch, sample selection, and playback parameters, all of which can be modulated via CV inputs, providing endless possibilities for dynamic sound design. Sample editing is made easy directly on the module, letting you loop, trim, slice, or copy without the need for external software. Whether you're capturing ambient textures or percussive hits, the STS's onboard sample editing capabilities ensure you're always in control.

Designed with the contemporary musician in mind, the STS supports microSD cards up to 256GB, making it a powerhouse for extensive sample libraries. The module's low-noise design ensures pristine audio quality, while its compact 20HP width means it fits seamlessly into any Eurorack setup.

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about 4ms Stereo Triggered Sampler.

Features and functionality

  • The 4ms Stereo Triggered Sampler (STS) can rapidly access samples post-recording, making it suitable for live sampling with minimal manual input if a gate is used for playback.

    Source
  • The module excels in handling extensive sample libraries quickly, provided the user maintains a well-organized sample collection.

    Source
  • Holding both bank buttons switches output from stereo to two separate mono channels, allowing individual manipulation of each channel.

    Source
  • Adjusting volume in stereo mode involves holding the Reverse button and turning the Start Pos knob, enabling gradual crossfade between channels.

    Source
  • Users experience a lag between trigger and CV input when pairing the STS with sequencers, often resulting in incorrect sample playback.

    Source

Comparisons

  • While the STS is less focused on sound design than Morphagene, Nebulae, or Clouds, it offers significant recording time and straightforward playability compared to the more complex Morphagene.

    Source

User experience

  • Owners highlight the STS's ability to handle long recordings, automatically splitting them at a 4GB limit without stopping, ensuring continuous recording capabilities.

    Source
  • The STS can be used in a live setup with mono outputs, which multiple users find suitable for live performances despite initial preferences for stereo.

    Source
  • Owners find the STS's inability to play samples on CV change without a trigger frustrating, particularly when trying to create consistent drum beats.

    Source

Use cases and applications

  • DJs have set up dual STS modules to mimic DJ decks, allowing for the mixing of entire tracks, thus illustrating its flexibility beyond traditional sampling.

    Source
  • Combining the STS with a Morphagene allows for dynamic live performances by separating sample layers into melodies, basses, and drums for manipulation.

    Source
  • The module is not ideal for live looping due to SD card limitations and the need for additional external modules, making it less efficient compared to the Dual Looping Delay.

    Source
  • The STS requires a trigger to play samples, which differs from some users' expectations of CV-based sample playback.

    Source

Software and compatibility

  • Firmware version 1.4b appears to offer limited improvements in resolving trigger and CV timing issues with the STS.

    Source

Critic Reviews

4MS Stereo Triggered Sampler

soundonsound.com

The 4ms Stereo Triggered Sampler is a dual-channel audio module that boasts high-fidelity recording capabilities and extensive CV control options, making it a promising addition for modular enthusiasts. However, its reliance on colored LEDs instead of a numeric display makes navigation cumbersome, and the lack of built-in resampling capabilities is a significant drawback. While the module opens up creative possibilities, especially in granular manipulation, it feels less intuitive and requires an external patch to fully utilize its potential. With its price point and the competition offering more user-friendly sampling solutions, the 4ms STS impresses with its unique features but falls short in usability.

4MS Stereo Triggered Sampler review | MusicRadar

musicradar.com

The 4MS Stereo Triggered Sampler excels with its intuitive layout and sound quality, making sample management a breeze with its intelligent system and impressive latency performance. However, it falls short by lacking the ability to layer loops like competitors, which may limit its appeal for more advanced users looking for multi-layered sampling options. Despite this, the sampler's versatility in creating unique sounds and its generous sample library make it a worthwhile addition for both beginners and seasoned musicians alike.
