What's New

New Features:
Freeze tracks - drastically reduces processing for tracks with IAA effects, and frees up the plugins for use on other tracks.
Loop Recording - allows continuous overwriting while it loops. Stop and undo after a good take.
Smaller audio buffers - sizes of 64 are now supported for low latency monitoring.
Rewritten audio engine for perfectly clean audio quality.
Volume/pan adjustments are filtered and interpolated, no 'zippering'.
Compressor uses exponential gain reduction metering.
Long-Touch zipped song project icon now has 'Open in' button for sharing the zip.
Final mixdown now uses loop markers as song start and end.
Final mixdown won't overwrite older mixdowns with same name.
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.
