2026-3-24 Release

Features

• ZMF v3 - Successor to RMF
  • Supports Vorbis, FLAC, and Opus samples
  • Cubic interpolation option in authoring, for smoother playback
  • New playback‑settings flags, including Classic Chorus
  • Utilizes LZMA for smaller file sizes than RMF/HSB
• Classic Chorus Mode
  • Emulates Beatnik 1.x chorus/reverb order for improved legacy compatibility
  • Beatnik later swapped the order of chorus and reverb to match the DLS spec
  • Classic Chorus mode is intended for older RMF files, but can be set as a flag in ZMF

NeoBAE Studio v0.10a (Alpha)

• Create, edit, preview, recompress, and convert MIDI, RMF, and ZMF
• Edit, preview, recompress, and convert HSB and ZSB soundbanks
• First public release, feedback welcome on the issue tracker or Discord.
• Alpha release, expect bugs

mod2rmf (Experimental, included with clitools)

• Convert ProTracker (.mod) and ScreamTracker (.s3m) modules to RMF or ZMF
• Early‑stage tool; results may vary depending on module structure

Fixes

• MIN_LOOP_SIZE was inadvertently set from 20 to 2 in August 2025. This has been fixed:
  • RMF is now limited to 20 frames, samples with smaller loops will not loop, as Beatnik intended
  • ZMF can do loops as small as 2 frames, great for mod2rmf

Known Issues

• macOS
  • zefidi: The player may take several seconds to appear
  • zefidi: Finder interactions may be interpreted as drag‑and‑drop

2026-3-13 Release

Update 2026-3-18

The binary releases were missing their executables, this has been fixed as of 2026-3-18

Features

• Implement BAEScript - a micro javascript-like language for controlling MIDI
  • Supported in playbae with --script argument
  • Advanced BAEScript editor in zefidi
  • No support for BAEScript in Android

Fixes

Known Issues

Special XP (non-SSE) Release

• A special release for Windows XP (for Pentium MMX and newer) is available as a RAR compressed ISO.
• The ISO contains NeoBAE, some sample media, sample banks, the WinXP SP3 installer, and a required Windows Update for MSVCRT.
• Due to most XP installs being lower resolution than modern systems, playlist functionality was disabled in zefidi to keep the player small.
• The ISO also includes a Dockerfile (and deps) to create the non-SSE toolchain for yourself
• The ISO can fit on a 650MB CD-RW

2026-2-27 Release

Known Issues
