Audio2MIDI 0.2.0

• Preview: press Play to hear the source audio and the transcription through the track. A slider mixes audio and MIDI; the MIDI plays on macOS's built-in General MIDI sounds, so nothing extra downloads.
• Piano roll: see every note, coloured per instrument, with a playhead you can click or move with the arrow keys.
• Align to beats: switch the parts to a version snapped to the detected beat grid, or keep the performance as played.
• Session restore: the transcription is saved with your project and comes back when you reopen it.
• Installer: Audio2MIDI-macOS.pkg installs the VST3 and AU into your user Library without an admin password and without the xattr step. It is not notarized: allow it once under System Settings → Privacy & Security → Open Anyway.
• Recording pauses while the DAW transport is stopped and tells you about empty takes, gaps and the 250 MB limit.
• Engine: the local MuScriptor server now exits when the DAW crashes instead of staying in the background.
• Part drags start as a system file drag immediately.

Universal (Apple Silicon + Intel), macOS 11+. Validated with pluginval (strictness 10, VST3 + AU), auval -strict and a real transcription run. Tested in the Standalone app; Logic, Ableton and FL Studio still need a hands-on check.
