Whorl: 16-Step Microsampler Sequencer with FX

Posted on 27. August 202627. August 2026 by Max Noizefield

Scrap Brain Audio has released Whorl, a new 16-step microslice-sequencer for macOS and Windows. The plugin turns any audio file into playable rhythmic patterns. Producers can drop drum breaks, synth stems, or field recordings directly onto the interface. In particular, Whorl analyzes transient onsets and spectral weight to divide the source into three slice groups. Sharp attacks become layer A. Tonal bodies become layer B. Meanwhile, sustaining textures become layer C. This approach helps isolate individual elements without manual slicing.

Three-Layer Microslicing
The three layers are a core part of the workflow. Attack, body, and texture slices map onto a 16-step grid. The grid supports 1/32 subdivisions and sustain ties. Users can also capture soft ambient room tone from the original sample. Each step can trigger custom effects on individual hits. For example, available effects include tape stops, half-bar reverses, filters, distortion, auto-pan, and delay.

Step-Based Effects and Pattern Tools
Whorl’s FX matrix offers three customizable effect profiles per step. These profiles combine distortion, filter, delay, reverse, tape stop, and auto-pan. In addition, the sequencer includes generative rhythm randomization. It also provides four pattern memory slots. More importantly, these slots can be switched live via MIDI notes.

Features

Microslicing: Automatically categorizes audio into Attack, Body, and Texture layers.
16-Step Modular Engine: 1/32 subdivisions, sustain ties, generative randomization, four pattern slots.
Step-Based FX Matrix: Three profiles with Distortion, Filter, Delay, Reverse, Tape Stop, Auto-Pan per step.

Price and Availability
Whorl is available for $39 until September 15. The regular price is $99. The plugin comes in AU, VST3, and standalone formats. It supports macOS with native Apple Silicon and Intel. Windows 10/11 64-bit is also supported. Therefore, it fits most modern production setups.

This release offers an interesting way to work with samples. The automatic three-way slicing could save time. Similarly, the per-step effects add hands-on sound design. As a result, Whorl may appeal to beat makers and experimental producers. However, the pattern memory is limited to four slots. The FX matrix is also limited to three profiles. Still, the intro price makes it a low-risk tool to try.
