NEW IN ELASTIC PHRASE A new ring view shows how each note stretches against an even grid. The phrase is now written on a staff, and there are new sounds to choose from. FIXED I fixed audio export: your phrases and songs now save as WAV properly. Touch handling on notes is also better — tap to switch a note on or off, drag to stretch it, and double-tap to choose its sound without changing its state. — METRONOME FIXED The metronome could freeze when you left it and came back, forcing you to reopen it from the menu. The audio engine now detects a stalled clock and rebuilds itself, so you can move between modules freely. STUDY TIME Your practice time now goes straight to your total when you press Stop — no need to save it by hand. Each play-to-stop stretch is a complete session, and the session clock resets so you always see what you're doing right now. COUNTDOWN TIMER Set a target in minutes and get an alert when you reach it. It counts down only while the metronome is sounding, so leaving your phone aside doesn't eat your session. EVEN TEMPO RAMP Tell it where to start, where to end, and how many minutes it should take. It works out the rest and spreads the change evenly — one BPM at a time, all steps identical, landing exactly on the minute you asked for. The count-in now plays at your starting tempo, so you enter with the right reference. DYNAMICS The downbeat accent has its own volume, separate from manual accents. You can finally raise one without dragging the other along. VOLUME CONTROLS Redesigned for fingers. Tap anywhere to set the level, or use the − / + buttons for fine adjustment. No more hunting for a tiny slider handle.
