OCTAVE - chart editor + auto-charter for YARG
Hello all! Been working on this for a while and it's finally ready to share.
What I set out to create A charting tool that was accessible for those who have never charted, and speeds up the process for those who already do.
What I ended up creating Desktop editor and auto-charting tool with a 2D piano roll, a live 3D highway preview that matches in-game, and a venue/timeline editor where lighting cues, camera cuts, videos, and stage effects sit on the same timeline as your notes. DAW-style stems mixer. Full .mid / .chart round-trip with no metadata loss. 100% local, MIT licensed.
...and many more things I couldn't list here!
Who is supported Windows, macOS, Linux.
>Note: macOS and Linux have not been fully tested, so please report any issues you see.
On the auto-charter (STRUM): Takes an MP3, YouTube link, or stems and outputs a full chart pack - drums, guitar, bass, keys, pro keys, vocals and harmonies with aligned lyrics. All difficulties included!
Here's what to expect:
- Drums are the strongest by a wide margin. On songs that sit well, the output is close to a hand-charted pass.
- Guitar, bass, keys, vocals won't always ship a perfect chart for you - they at worst frame the song so you're correcting a draft instead of starting from a blank timeline, they at best need a small tweak or two.
- Pre-split stems improve quality noticeably across everything.
Please let me know where I went right and where I went wrong The Github is open to issues, so please report anything wrong or anything you'd like to see. Completely open to all criticisms and feedback.

A big thank you to anyone who takes time to try out the tool!! I am excited to see the community have some fun with it.
>On a fun side note, I had a paper published about the intricacies of the STRUM auto-charting model. Feel free to read for more technical details, including model benchmarks and more: https://arxiv.org/abs/2605.12135
