Freeze tracks - drastically reduces processing for tracks with IAA effects, and frees up the plugins for use on other tracks. To use, make sure you have IAA effects on the track, and tap the 'Freeze' button, next to the Arm button, on the track. You can still adjust volume, pan, and bus send, of a frozen track.
Loop Recording - allows continuous overwriting while it loops. Stop and undo after a good take. To use, make sure the loop section is more than a couple seconds in length. For precise record start and stop points, use 'Punch' from the Menu and place the punch points within the loop points.
Smaller audio buffers - sizes of 64 (1.4 ms) are now supported for low latency monitoring. Warning - some apps don't support buffers this small and may glitch, snap, crackle, and pop. So if you get audio dropouts when recording other apps, please try longer buffer sizes. MultiTrack doesn't have this problem.
Volume/pan adjustments are filtered and interpolated, no 'zippering'. Mostly only noticeable with loud sound sources and quick movements.
Compressor uses exponential gain reduction metering. Make it much easier to see the amount of gain reduction.
Long-Touch zipped song project icon now has 'Open in' button for sharing the zip. Use it to send project zip files to Dropbox, etc.
Final mixdown now uses loop markers as song start and end. Makes it easy to produce loops, and to trim the start and end of the song without an extra step.
Final mixdown won't overwrite older mixdowns with same name. File exports will always use a unique name by appending a numeric identifier to the end. ie. '(mix)My Song (1).wav', '(mix) My Song (2).wav'
All sorting/ordering uses numeric sort (Song, Shared, Inputs, IAA effects, generators, instruments).
Silence rendered to IAA plugins when doing mixdown/copy operation, to flush out buffers.
Wi-Fi web server lists songs in same order as shown in multitrack.
Track and bin download filenames now contain the song name as prefix.
