Release Notes 2.5.1 adds the following features: - Tap Tempo Start Have you ever been in a situation where you want to play to a click, but the guitarist or pianist wants to start the song on their own? Now it's easy... In a Playlist, tap the gear button on the right and enable "Tap Tempo Start". You can choose the number of taps. Then, when you get to that item in the Playlist, just tap the play button in time with the guitarist and PolyNome will start in time with your tapping! - "Ready, And" voice cue in Playlists. On the Playlist Controls page, when Auto Advance and Play When Advancing are on, you can choose a "Ready, And" voice cue that will cue you as the next item is about to start. (This used to be part of the "Announce Item" feature, and it used to say "3, 4", but that wasn't great in odd time signatures.) It also fixes some bugs. Please let me know via the Help or About page if you find any others. If you have time to leave (or update) an App Store review, it's much appreciated and really helps with future development. Any questions, just get in touch via the App. Thanks for using PolyNome! Joe
