0x808

0x808 brings sequencing, synthesis, sampling, and arrangement into a free desktop workstation for beat-makers who want to work standalone or inside a DAW. Its 16-track grid and three synthesis modes give it range beyond a basic drum sequencer. It is a strong fit across Linux, macOS, and Windows, with Bluetooth MIDI and MP3 export carrying specific caveats.

Overview

Use 0x808 as a standalone drum machine and synth, or load its VST3 or CLAP plugin into a DAW. Terminal and standalone frontends add further ways to work. That flexibility suits producers who want one tool for building patterns and shaping sounds, whether or not a DAW is part of their setup.

The project is MIT-licensed and says its dependencies are vendored, with no external runtime dependencies. Releases include installable and portable formats for Windows, tarballs and AppImages for Linux, and DMGs and ZIPs for macOS, giving desktop users a choice of package type.

Key features

Sequencing and sound design

The 16-track drum grid has per-step velocity and pitch controls, plus mute and solo. These controls let producers shape individual hits and manage parts directly in a pattern. Subtractive, four-operator FM, and wavetable synthesis, each with built-in presets, make 0x808 useful for creating sounds as well as arranging drum parts.

The sample browser loads WAV, MP3, and FLAC, and the project includes 72 CC0 drum samples. That gives users a ready set of sounds and room to bring in samples in common audio formats.

Arrangement, effects, and export

Patterns can be chained in song or perform mode, and per-track and master-bus effects include filter, delay, reverb, overdrive, fuzz, and chorus. This combination supports both arranging patterns and shaping their sound within the workstation.

Offline WAV export offers 16-, 24-, and 32-bit output. MP3 export spans 128–320k, but requires an optional build setting, which makes WAV the more straightforward route for users who need export without changing that setting.

DAW and controller support

VST3 and CLAP versions are available for Linux, macOS, and Windows and install into the corresponding plugin folders. USB MIDI works on all three platforms. Bluetooth MIDI is not directly supported; the project describes a Windows virtual-port bridge workaround, so users who depend on direct Bluetooth connections should look elsewhere.

Pricing

0x808 is free and open source under the MIT license. There are no paid plans to choose between, making it a practical option for producers who want a capable desktop drum machine and synth without a software purchase.

Platforms

0x808 is a desktop application for Linux, macOS, and Windows, with standalone builds and VST3 and CLAP plugins for DAWs on those platforms. The releases page offers platform-specific installers or archives, including portable ZIPs for Windows and ZIPs for macOS. USB MIDI is supported across the same three operating systems.

Who it's for

Choose 0x808 if you want a free desktop setup that combines step sequencing, sample import, synthesis, effects, and pattern chaining. It suits beat-makers who value both standalone use and DAW integration, or who want to move between those workflows. Producers who require direct Bluetooth MIDI support, or MP3 export without an optional build setting, are better served by another tool.

Pros and cons

Pros

• Free and MIT-licensed, with standalone, VST3, and CLAP options across Linux, macOS, and Windows.
• A 16-track grid with per-step velocity and pitch controls, plus three synthesis modes, covers both beat programming and sound creation.
• WAV, MP3, and FLAC sample import, 72 included CC0 drum samples, pattern chaining, and six named effects give a beat-making setup considerable scope.
• USB MIDI works on all three desktop platforms, and the project says it has no external runtime dependencies.

Cons

• Bluetooth MIDI is not directly supported, which rules it out for workflows that rely on a direct Bluetooth controller connection.
• MP3 export requires an optional build setting, adding a configuration step for users who need that format.

Verdict

0x808 is an easy recommendation for desktop beat-makers who want a free, open-source workstation with sequencing, synthesis, samples, effects, and DAW plugins in one package. Its platform coverage and standalone-to-plugin flexibility are the main reasons to choose it. Look elsewhere if direct Bluetooth MIDI is essential or MP3 export must work without an optional build setting.
