• New Synth mode: a saved song's chords fall onto the keyboard as blocks that light up when you play them. Slow it down, loop 4 chords, or have it wait for you. • Better 7th chords: Tonalyn hears 7ths more often and shows the right chord more of the time. • Fixed "Music stopped" showing up while music was still playing. • Ready for iPhone Duo: the big inner screen gets a roomier layout with two octaves of keys.

Small fixes and improvements.

• Steadier chords: fewer quick wrong chords flash up while a song plays. • Hears quieter music after loud parts instead of stopping. • Record mode: tap a chord to fix it. Your fix is saved and copied to repeated sections. • Record mode: drag a chord change to move it earlier or later. • Tonalyn now lets you know when an update is available.

- Chords start showing as soon as the music starts, before the song is recognised. - Chord changes show up closer to when you hear them. - Tonalyn notices sooner when the music stops, and picks back up when it starts again. - Quiet intros and single-note riffs no longer count as the music stopping. - Fewer stray out-of-key chords flashing up.

- A cleaner look across the app. - Chords are timed better when a song plays through a second time. - Free Play no longer shows a MIDI label when no MIDI keyboard is connected. - Changing Keys settings no longer makes Tonalyn re-detect a song's chords from scratch.
