Kid Bunka / Handheld audio lab

Dig. Chop.
Make it hit.

A fragment from an archive. A drum from your collection. A sound you have never heard before. Turn it into a track with TrackWerk.

An independent fork of PocketTracker by conanizer and contributors.

ORIGIN / OPEN SOURCE

Built on PocketTracker.
Developed as TrackWerk.

TrackWerk is an independent GPL-3.0-or-later fork of PocketTracker by conanizer and contributors. Their work is the foundation of this project, and its authorship remains visible.

THE FOUNDATION

PocketTracker’s established workflow

The tracker, sampler, sample editor, mixer, export tools and handheld button workflow come from the upstream project. TrackWerk keeps that musical foundation and credits its original developers.

THIS INDEPENDENT FORK

Kid Bunka’s TrackWerk direction

This fork develops the expanded Studio, synthesis presets, performance banks, archive-to-sample workflow, Drumlab, visual identity, typefaces and handheld fixes described here. TrackWerk is maintained separately, with its own name, artwork and public Android identity.

Selected synthesis and effect algorithms are adapted from Mutable Instruments’ open DSP by Emilie Gillet and other contributors. Those component credits are separate from PocketTracker’s authorship. Read the complete credits and licenses ↗

01 / From the archive to the pattern

A good find is
only the beginning.

Follow a sound that catches your ear. Preview it, isolate the useful part and put it under your fingers. The Source Sampler stays inside the Studio.

DISCOVER / INTERNET ARCHIVE

Find a direction before you know a title.

Browse by genre, try Random for inspiration or search for something you already found. A result can contain several tracks: open the result, then choose the recording you want to hear.

Follow the full workflow
A SOURCE IS A STARTING POINT

Archive access is not a reuse license. Choose recordings you own, public-domain material or a license that permits your intended use. Keep the source details with the clip. Online sources require a supported device with a working network connection. The illustrated example is Modern Jazz Samba by Kevin MacLeod, CC BY 4.0.

02 / Hear the difference

One fragment.
Two directions.

Hip-hop to drum & bass. Follow the choices, hear the changes and see the actual TrackWerk workflow. Music and captions. No voiceover.

A complete jazz phrase, two newly programmed grooves. The session is edited for clarity; the clip’s gentle, pitch-preserving tempo preparation is described in the credits.

03 / The Studio

Go beyond
the first idea.

Keep the tracker at the center. Open a dedicated Studio when you want to design a voice, shape the mix or play an effect into the moment.

SYNTHESIS / PLAY IT WHILE YOU SHAPE IT

Different engines.
Different possibilities.

Explore Plaits, Braids, Rings, Elements, Clouds-derived granular models and additional Studio DSP voices. Engine-specific parameters keep the character of each family in view.

Choose from 2,048 categorized synth presets, including drums. Audition a sustained note, or edit a loaded synth while its sequence plays.

OscillatorsFMPhysical modelsGranular
Inside the synthesis workflow
STUDIO / SYNTHLIVE EDITING
Underlying engines share models and articulations. This is not complete emulation of every hardware module.

SAMPLES / SMALL DETAILS MATTER

Long source.
Precise cut.

Preview and seek through a long WAV from storage. Mark a region, save a new excerpt and open it for detailed slicing. The source stays intact.

Fine zoom, manual and transient slices, fades, normalization, declicking and undo help turn the cut into an instrument.

Work with a long recording

Full-source preview is separate from the RAM needed to edit an excerpt.

PERFORMANCE / HOLD THE MOMENT

Sixty-four ways
to interrupt a loop.

Eight banks of eight momentary punch effects. Select a pad and hold A. Release to bring the mix back. Rhythm, Tape, Filter, Dub/Space, Cut/Glitch, Granular, Modulation and Damage.

Use the direct shortcut, perform a few gestures and capture your own output with internal resampling.

Learn the performance controls

Momentary effects are released on exit, stop or lost controller focus.

02 / CHARACTER

Effects library

64 reverbs, 64 delays, 96 Studio FX and 32 mastering presets. Categorized starting points for rooms, tape echoes, resonators, granular textures and controlled color.

Build a useful effect chain ↗
03 / THE FINISH

Mastering

Drive, dynamics, stereo width, high-pass filtering, output gain and peak ceiling. Refine the balance and render a mix or stems for the next stage.

Finish with intention ↗

04 / Your screen, your pace

A different face.
The same fingers.

Choose one of 17 typefaces, 50 color palettes and 18 surface materials. Readable studio faces sit alongside broken raster lettering, terminal styles and demoscene textures.

The established button workflow remains. Your selected appearance, control mappings and existing project paths stay in place when using the matching update.

Choose the font, palette and material independently.

05 / Get TrackWerk

Choose the machine.
Keep the music.

TrackWerk 0.9 is a beta. Use the package for your platform, follow its first-start guide and keep a copy of your work before updating.

TrackWerk 0.9 beta is available. Choose the package for your platform and follow the field guide. Matching source and checksums accompany the release.

A / ANDROID

Android handhelds

Android 8 or newer. ARM64, ARMv7 and x86_64 in one APK. Controller behavior and audio input still depend on the device.

First install & safe updates ↗
Coming from an earlier beta app?

The public TrackWerk APK has its own Android identity and installs alongside the earlier app. Keep the old app installed, export any app-private projects and media to a shared folder, then grant TrackWerk access to that folder. Settings and control bindings need their own setup. Separately supplied private compatibility updates remain a private route.

Read the Android migration steps ↗
B / TRIMUI BRICK

Brick + KNULLI

A native Linux build using the established standalone launcher. Your sample library stays in its existing data folder.

KNULLI, samples & first start ↗
C / MIYOO + ONION

Mini & Mini Plus

Mini uses local audio. Mini Plus adds supported Internet sources over Wi-Fi. The new long-WAV preview keeps full-file decoding out of the preview path.

Choose the right Miyoo build ↗
An update should keep your work.

Use the supplied program updater on Linux handhelds. Existing TrackWerk Android installs use matching signed updates; migration from an earlier app identity is a separate step. Keep Samples, Projects and Presets in place, and retain the old app until its internal data is exported. Existing Linux data folders remain for compatibility. Read the update route before copying files.

06 / An honest beta

Know the
test boundary.

The engine, workflows and update preservation have automated, emulator and constrained ARM checks. Earlier private builds were used on real handhelds. Final 0.9 device acceptance is ongoing.

See the full compatibility table ↗
Archive sampling
Real HTTPS search, preview, range rendering and native import tested in software. Mini Plus network fix included; physical Wi-Fi confirmation pending.
Long WAV files
Storage preview and excerpt workflows tested with 32 MiB, 160 MiB and a 2.4 GB sparse test source. Editing limits still follow free RAM.
Recording
Internal resampling is implemented. Physical microphones and class-compliant interfaces on Android/Brick need device tests. Miyoo profiles do not expose physical input. Direct iPhone-to-Brick USB input failed in the tested setup.
M8 import
A supported sampler/arrangement subset. Unsupported engines and effects are reported and omitted. Keep the original song.
