The first release of SQRL-1, firmware for the M-VAVE FM-1, built on Felucca 1.5.6. Every pair is a SOUND and a NOTE engine, picked on the wheel (hold HOME). What it adds over Felucca is in the changelog.
Install from databurn.org/sqrl/install in Chrome or Edge over USB; the page installs the package below. Back up first if you have music on the FM-1; the README says how to go back to official V15. Installing is at your own risk.

Getting started
From the project's README ("Install"):
The installer is a web page, databurn.org/sqrl/install, for Chrome or Edge over USB. Each release also attaches its package to the GitHub release page. Installing is at your own risk.
- Back up first if you have music on the FM-1. Felucca's editor makes a complete backup; SQRL-1 reads it.
- To go back, download official V15, FM-1.fwsc, from M-VAVE's download page (FM-1, "PC Firmware") and use the installer's Return to official V15. It checks that the file is V15, saves a complete backup of your SQRL-1 music and sounds to the computer, then installs it. This has been tried on a device. M-VAVE's own updater, M-UPGRADE, does not see an FM-1 running SQRL-1; once the FM-1 is back on V15, M-UPGRADE works as it does on stock firmware.
- If an install is interrupted, press Install again: it is built to resume. An FM-1 that no longer starts at all can be recovered with FM-1-transporter (see Known issues).
