Hey everyone,
I've just released v1.1.0 of chirashi, a CLI tool for moving sliced loops between hardware and open samplers.
The highlight of this release is a reverse-engineered REX2 encoder. It’s written in pure Go (no SDKs/CGo required) and produces bit-perfect .rx2 files that pass ReCycle validation, and new MPC support.
What’s new in v1.1.0:
- Akai MPC Support: Export directly to .xpm Drum Programs (128 pads mapped instantly).
- Open Standards: Added SFZ and Decent Sampler (.dspreset) export with full slice mapping.
- Auto-Detection: Smart sample-rate detection and batch processing for WAV/AIFF/CAF inputs.
- Hardware Ready: Optimized for MPC, M8 Tracker, Octatrack, Polyend, OP-1/XY, and Digitakt II.
It's open source, runs on macOS (Intel/M1+), Linux (including ARM), and Windows. No install needed—just a single binary.
GitHub: https://github.com/g-lok/chirashi
Brew: brew install g-lok/tap/chirashi
If you've got a library of REX files gathering dust, this is the easiest way to get them into your hardware.
I don't own most of these devices, so anybody who owns any of these things please try it out and let me know if it works. if it doesn't, please create a new github issue to report it the bug.
Enjoy!
