Zrythm v2 Builds Thread

alex · October 23, 2025, 11:56pm

Normally, nightly builds are only available to subscribers but for a limited time I will post the latest v2 installers here occasionally so everyone can try them out and give feedback before we release a usable version.

Zrythm v2 is still being actively developed and if you want to support our work please purchase a plan from our website or donate. You can also help in other ways.

Zrythm is distributed as free software under the GNU AGPLv3 license - note that there is absolutely no warranty.

Version 2.0.0-alpha.0+123.5ef4f829cfee

GNU/Linux (x86_64) | Windows (64-bit) | macOS (Apple Silicon & Intel)

Last update: 2025/12/05

Installation Instructions

For Windows and Mac, just double click and follow the instructions and Zrythm will be installed as an application. For GNU/Linux, just run bin/zrythm directly after extracting the archive (no installation needed).

System Requirements

macOS 13 or higher (including macOS 26)
Windows 10 (1809 or later) or 11 with a CPU supporting AVX instructions
Linux with GNU libc 2.31 or higher and X11/Xwayland with a CPU supporting SSE4.2 instructions

Nice! Very excited to try a QT version.

NOPAPA · October 30, 2025, 6:49pm

just wanna say, thats why i made this account,
i never got 1.0.0 to work, tried with gpt to repair it so long.
Installed 2.0.0 and finally on windows 10, it works. thank you.
glad to try this

mylofymusic · November 4, 2025, 11:26am

Today I built from master and the GUI already feels much smoother than v1. Obviously many items are missing, e.g. re-opening projects, dragndrop, re-sizing MIDI notes etc. The theme follows the system, which is nice. No issues with the audio devices, haven’t tested MIDI input though. I suppose it’s too early for bug reports, but let us know when you need more in-depth testing. Looking forward to seeing v2 catching up to v1 funcionality

alex · November 4, 2025, 1:45pm

Thanks for testing! It’s still early for in-depth testing but general feedback to see if we are on the right track is welcome (like audio devices working, project window showing without issues, plugin scan working, fonts and icons working, timeline being operational, etc.). So far it sounds like there are no major issues other than unimplemented features.

pastaya · November 6, 2025, 3:45pm

i think the position of the zrythm logo and the text below it is kinda “offcenter” on darwin

alex · November 8, 2025, 1:17am

Will fix/remove that but it’s really low priority. UI polishing will come after the main features are implemented, unless it’s something major that prevents the user from doing something or a fundamental UI change.

vojvodinosaurus · November 21, 2025, 9:07am

bad news: doesnt work on my windows 10 laptop! installs fine but when i try open a new project nothing happens, app closes and disappears from task manager. not sure if install location or my quadro gpu or my cpu have anything to do with this

alex · November 21, 2025, 9:21am

What is your CPU? These builds currentl require AVX support (a CPU from the last 10 years or so would theoretically be fine).

vojvodinosaurus · November 21, 2025, 9:40am

i7-4810mq, checked hwinfo it says both avx and avx2 are supported

alex · November 21, 2025, 11:49am

That sounds like another issue then. Can you please check the log file somewhere under AppData/Local/Zrythm.org/Zrythm/cache ?

Tried on Arch Linux: project window opens fine, but the application crashes when I click Audio/MIDI Setup on the Devices menu.

@vojvodinosaurus Log looks normal other than getting cutoff unexpectedly. Is your Windows 10 version 1809 or later? If so, the only way to debug this would be with Visual Studio, but it needs a debug build. Can you please try installing this debug version instead? Then opening and running zrythm.exe from the installation path in program files via Visual Studio? It will show you a backtrace when it crashes. That will help us pinpoint the issue.

@rman Thanks for testing! Can you also check the latest log file for any errors or suspicious warnings in ~/.cache/Zrythm.org/Zrythm? If everything looks ok, can you please try this debug version so we can get a more helpful backtrace?

alex · November 22, 2025, 5:50am

Also, what DE are you using, and does exporting QT_NO_GLIB=1 before running zrythm fix the issue? For example:

export QT_NO_GLIB=1

./bin/zrythm

rman · November 22, 2025, 8:32am

@alex thank you for the feedback!
There’s nothing suspicious in the log file, it doesn’t output anything when the crash happens. I’ve tried with QT_NO_GLIB=1, same result. My desktop environment is Niri, pure Wayland without any X / Xwayland packages.

Here’s the output using the debug build:

Ok this is the issue. Zrythm requires X11 (either on its own or via Xwayland). The reason is that windows managed by JUCE (such as the device manager and plugin windows) require X11 (at least for the time being). I’ll make this more clear and maybe add an error message if no x11 was detected.

vojvodinosaurus · November 22, 2025, 11:01am

i’m on 22H2 and it seems like latest version of vs is too new so maybe i can dl an older vs version to debug with

alex · November 22, 2025, 11:53am

You can use other debuggers as well, doesn’t have to be Visual Studio. It’s just that Visual Studio is the easiest to obtain and most powerful. I don’t know how other debuggers work but you could try Dr. Memory
