Guidonica 2026.10.0

Added

• Practise 9/8 and 12/8: compound triple and quadruple meters, with the same pulse choice as 6/8 (ADR 0076).
• Pick which notes to read: each note name can be switched on or off in Settings, and Beginner starts with a few notes only (ADR 0070).
• The welcome steps now ask for a time signature too, after the level and the clef (ADR 0071).
• Guidonica works offline: after one visit, it opens and plays with no connection (ADR 0063).
• What's new: after an update, Guidonica lists what changed since your last visit. About shows the version and the full list (ADR 0078).
• A Ko-fi link in About and in the footer, for voluntary tips (ADR 0074).
• About explains how Guidonica is made, including the AI coding assistant used to write it (ADR 0075).

Changed

• The beat lights and the click now have three accent levels: the downbeat, the bar's middle pulse (beat 3 of 4/4, beat 4 of 6/8) and the other beats (ADR 0072).
• The levels progress more evenly in tempo, intervals and note values (ADR 0070).
• The level button shows a dumbbell, so it no longer looks like a signal-strength meter (ADR 0073).
• Rhythms come from a new generator: every figure that may appear in a bar can now appear, and rests are spelled the way a copyist would write them (ADRs 0064, 0065).
• Rests can fill whole beats and whole bars, and tuplets can mix note values, such as a quarter and an eighth under a triplet bracket (ADRs 0065, 0066).
• Melodies built from leaps only, such as thirds or fifths, now reach every note of the range (ADR 0066).

Internal

• Release channels: guidonica.it serves the latest release and guidonica.it/nightly/ the latest commit, with separate settings and offline caches (ADR 0078).
• Security and privacy audit, least-privilege CI with pinned actions (ADR 0069), and CI actions on Node 24 (ADR 0077).
• Contributor terms with DCO sign-off, a trademark policy and a security contact (ADRs 0067, 0068).
• robots.txt and sitemap.xml for search engines (ADR 0062).
