Last chance to get maximum discount to NUO-STEMS 4 ‼️​

Starting January 1, 2026 NUO-STEMS 4 will be released as public beta.
This means that anybody will be able to download it without the need to write me.

What it also means is that it’s your last chance to get maximum discount while NUO-STEMS 4 is still in closed alpha (2 days left).

Upon beta release, users who already own NUO-STEMS 3 will get emails with upgrade coupons, but discount will be much lower.

Current upgrade price for NUO-STEMS 4 alpha is 19.99 (after coupon is applied for 40% discount from regular price of 33.99).

Public beta discount will be 20% for those who already own NUO-STEMS 3.

Please write me to [email protected] or in private messages to get the installer of NUO-STEMS 4 alpha.

Release 3.2.0-alpha.1 | New compression format

Features​

  • New compression format: AAC 320 kbps (CBR).
    • Traktor Pro 4 introduced this format for native stems, and it's now supported by NUO-STEMS.
    • Previous AAC 256 (VBR) is still supported and remains the dafault option in NUO-STEMS. Because it provides 25% smaller file size.

Release 3.1.1-alpha.19 & 20

Changes:

  • Fixed a bug when NUO-STEMS froze on 3% (crashed) on Windows when using NVIDIA GPU with < 4GB of VRAM, even if setting "GPU acceleration" to "disabled (force CPU only)".
  • Fixed a bug on Windows where pressing "Stop Processing" button triggered an error (even though everything was working fine).
  • Fixed a bug on Windows where if the Queue finished all tasks, it triggered an error (even though everything was working fine).

Picture

It is still work-in-progress, but it's already source-available on GitHub: https://github.com/dj-nuo/nuo-stems
If you want to contribute to Docs - feel free.
In the nearest future I'm considering adding NUO-STEMS frontend code there as well for NUO-STEMS 4 (which is not released yet, and release date is unknown).

Why?
It allows those of you who are interested, to bring new UX/features to frontend or Docs of NUO-STEMS. This includes but not limited to translations. The License is completely copyright, so the goal here is just to give you tools to affect the project more as we go forward 🙂
