B-Step Sequencer
Key Features
- Creates MIDI patterns for melodies, arpeggios, chord progressions, basslines, drum grooves, and experimental parts.
- Combines 16-step sequencing with up to four independent tracks and 16 patterns for layered phrase building.
- Includes chord programming, shuffle, ratcheting, probability, reverse playback, and partial bar replay for moving patterns.
- Supports drag-and-drop copying, multi-drag editing, bar snapshots, and project notes for fast arrangement work.
- Provides MIDI clock sync, MIDI thru, MIDI learn, controller feedback, and native Novation Launchpad support.
- Runs as a plugin or standalone-style MIDI tool, with current developer-controlled nightly assets for Windows, macOS, and Linux.
Description
B-Step Sequencer is a MIDI-generating step sequencer for building melodic loops, chord progressions, arpeggios, basslines, drum grooves, and experimental patterns. Originally developed by Monoplugs, it is now maintained as an open-source Surge Synth Team project with downloadable nightly builds for Windows, macOS, and Linux.
The workflow is built around 16-step pattern creation with multiple tracks, chord programming, shuffle, ratcheting, probability, reverse playback, and drag-and-drop editing. It is most useful when you want a dedicated pattern instrument that can drive other synths or hardware over MIDI rather than another note editor buried inside a DAW.
B-Step's appeal is its hands-on sequencing surface: Launchpad support, MIDI learn, controller feedback, pattern chaining, bar snapshots, project notes, and embedded guidance all point toward live performance and fast iteration. User discussion around the older Monoplugs release consistently highlights the clean interface, low overhead, and chord-focused sequencing as the reasons it stands apart from basic arpeggiators.

Frequently Asked Questions
Who maintains B-Step Sequencer now?
B-Step was originally authored by Monoplugs and Thomas Arndt. The current public project page is maintained by the Surge Synth Team, which states that the source became open source in March 2022.
Does B-Step generate audio by itself?
No. B-Step is primarily a MIDI-generating sequencer, so it is designed to trigger software instruments, hardware synths, or other MIDI destinations.
Why use B-Step instead of a normal DAW piano roll?
B-Step is built around pattern performance rather than linear note editing. Ratcheting, probability, chord programming, MIDI control, snapshots, and Launchpad support make it better suited to evolving loops and live manipulation.
Is the current download route a mirrored SSA file?
No. The SSA entry points to the developer-controlled GitHub Nightly release page, where users choose the current Windows, macOS, or Linux asset directly from the upstream project.
