What's New in 408Jazz
1.1
July 13, 2026
What's New in Version 1.1 Voice Training improvements — The solfège reference tone now plays at consistent volume across all 8 scale degrees. Sol, La, Ti, and the upper Do were quieter than the rest in 1.0; that's fixed. Modal Colour Guide — Each mode card now shows a mini piano keyboard with the scale degrees highlighted in the mode's colour, so you can see the pattern at a glance. Dorian's colour has also been updated for better readability. Premium UI refresh — Darker, richer interface throughout with gold accents, glass-style cards, and a consistent dark tab and navigation bar. Bug fixes — Background noise removed from the voice reference tone. Minor layout and colour fixes across Chord Library and Ear Training.
