A housekeeping release: GHOULBOX makes room for what comes next. The firmware had about 4.5 KB of space left; 2.2 frees it up to 23.8 KB without changing what you see or hear, so future fixes and features have somewhere to go.
Install or update: first save a backup (the installer doesn't make one): open the web editor, connect the FM-1, and on the Settings tab press Save backup. Then open https://ghoulbox.messy.quest/webapp/installer/ in Chrome or Edge and press Install.

What's new in 2.2
- More room inside. The boot and ABOUT artwork and the button labels are stored compressed. They look exactly as before, pixel for pixel.
- FM6 math refined. The 6-operator FM engine uses a smaller, more precise pitch and level table. The sounds are the same to the ear.
- USB audio is 44.1 kHz only. The FM-1 still shows up on a computer as a stereo USB audio input, at 44.1 kHz. Computers convert to 48 kHz on their own. A DAW using the FM-1 directly as its audio interface needs a 44.1 kHz project (or an aggregate device) now. The headphone/line output is unchanged.
