A richer Temperament Explorer: - Explore fifths as a circle, spiral, or chain, with colored major thirds that make tuning differences easier to see. - Tap thirds, fifths, and chords to hear them using the new sound picker. - Compare major and minor chord progressions, including two Bach chorales. - Discover each temperament’s purest and widest intervals, with clearer comparisons and improved PDF export. Keep Favorites at the top of your temperament list. Choose the new arrangement in Settings › Temperaments. More improvements: - New chord notation options in Settings › Appearance. - Optional volume controls for Fine Tuna’s own sounds. - Inspect and play individual note occurrences in Passage Review. - Clearer pitch and temperament reminders, bookmark replacement confirmation, and external microphone handling. - Improved Explorer layouts on iPhone Duo.
