BeRoTrackerPattern editor
The grid as it always was, with 256 channels numbered in hex from 00. Selections transpose, vary, roll and amplify, a block grows to the length of the clipboard, and a whole pattern goes back out as a sample.
Version 1.00.2026.08.16 · Linux & Windows
BeRoTracker
Music written as patterns of notes over sampled instruments, edited from the keyboard, in the tradition of Impulse Tracker — with every one of its axes widened. One archive holds both systems, and nothing has to be installed for it.
What it does
A tracker, and then the room around it
Everything a tracker of this kind is expected to have, and beside it the things it was always missing: drum patterns of its own, a modular route, plugins from the outside world, and an FM chip that counts as a channel like any other.
Drum patterns
A second kind of pattern beside the note grid, with drum instruments and an order list of its own. A second press on the same key leads over to them and back again.
Samples and instruments
Envelopes with tools for doubling, halving and ADSR, jump points, note maps, and a waveform editor that carries effects and a small synthesizer. Resampling where other trackers only resize.
Modular routing
Operators wired into a route: the amplifier, a parametric EQ with presets, the effects the engine brings along, and single FM voices among them.
Plugins
VST2, VST3, CLAP and the tracker's own BTP. They are scanned once and remembered, they open their own window, and their parameters lie open to automation.
MIDI, in and out
MIDI files come in and go back out, controllers drive automations picked per column, and what the tracker plays can leave through a MIDI port to whatever is listening.
The FM chip
OPL3 is a channel like any other: its own instruments, kept in the BRT file, answering
to ^^^ and === the same way a sample does.
Its own screen
Everything is drawn through OpenGL, at whatever size the window has. A high-resolution font for large screens, the 8×8 oldschool look kept beside it, and sixteen colours that come out of a palette file.
Portable, in the plain sense
Unpack it somewhere and start it. Settings, caches and the log lie beside the executable, and nothing else on the machine is touched.
The engine
What happens between the note and the speaker
The mixer is the part that has been rewritten the most often, and it shows: the interpolation is a choice, not a fixed quality, and it reaches from nearest neighbour to a windowed SINC over a thousand taps.
- Mixing
- 256 channels, volume ramping and click removal, retro low and high pass beside the biquad filters
- Resampling
- Nearest, linear, cubic spline, polyphase FIR, and windowed SINC from 8 up to 1024 taps
- Effects
- A parametric EQ with presets, the amplifier, and every plugin that was found, wired where you want them
- Audio, Linux
- ALSA, PipeWire, PulseAudio, JACK
- Audio, Windows
- WinMM, WASAPI, DirectSound, ASIO
- Export
- WAV and MIDI, the whole song or one channel, one instrument, one sample at a time
Sixteen colours, and which sixteen is up to you
Palettes are read from files and can be written back. Seven are built in; Camouflage is the one the tracker starts with.
Formats
What it opens, and what it leaves behind
BRT is the only format wide enough for everything the tracker can do; the others reach as far as they reach.

Everything in the load list is also taken out of a ZIP, an archive inside an
archive included, and a module goes back into one when the name it is saved under ends in
.zip or in a z.
Requirements
What the machine has to bring
- Graphics
- OpenGL 4.3, compatibility profile. Cards have carried it since 2009 and 2010; where it cannot be had, the tracker says so and stops rather than draw half a screen.
- Linux
- 64 bit x86, an X server or a Wayland compositor. Under Wayland
libxkbcommonand EGL are wanted; without the first there is a window but no keyboard. - Windows
- 64 bit x86. Nothing has to be installed beside it — the executable asks only for DLLs which belong to Windows itself.
- Audio
- Whichever of the backends above the system has. One of them is usually already there.
- Keyboard
- The note keys follow the layout, set as QWERTY, QWERTZ or AZERTY. Alt Gr counts as an alt key, on every system.
- Disk
- What the archive unpacks to, and beside it the handful of files the tracker writes for itself.
Download
One archive, both systems
The Linux binary and the Windows executable travel together, with the icons, the desktop entry and the equalizer presets. Unpack it where you like.
