• New engine: acid, a TB-303 (X0X's, from Open303), with the Devilfish controls, Soft and RAT drive, and its own picture of the drive.
• New kit models: the 909 kick, snare, tom, rim and clap (9W9's circuits), and the 909 closed hat, open hat, ride and crash, played from ER-99's samples. The cymbals' samples come with the installer: install with the web installer so they are written too.
• Harmony: a track can follow the conductor's chord, not just its scale (follow modes harmony and chord deg). Thanks to darosh.
• A new player, random: each step draws a note from a pool of pitches you pick (hold a step, SEQ), with chances for notes, pitch, rhythm, timing, velocity and gate, and octaves down and up. Thanks to darosh.
• Large type (Setup › SEL › LARGE TYPE): bigger labels, values and header on every page; the hints stay as they were.
• On a kit's EDIT pages, the white keys now write steps: pick a sound with its black key, tap a white key to put it on that step. Hold a step and turn a knob to lock it. Hold EDIT to play the kit as before.
• CC IN (Setup › SEL): endless, for endless encoders sending relative values, such as a Launchkey's. Absolute stays the default.
• Menus follow one rule: names in capitals, values in bold, ↵ where SEL confirms, ▸ where ALGO changes it at once.
• Fixed: USB audio on macOS 15.
• The acid engine and the 909 cymbals use less CPU (after Optimist).
• The samples page can leave LOOM-8's own sounds out, to make room for yours.
• Projects are stored more compactly, so a small project takes less room. Projects and backups from 0.11 load as they were.
