Sony has updated ACID to v6.0c.

Notable Fixes/Changes:

• Fixed a problem that could cause a hang when AAS's Lounge Lizard 3 is opened and an ACID project is autosaved.
• Default patch settings are not applied to VSTi soft synths when new tracks are added to a project.
• Fixed a bug so MP3s with Unicode ID3 tag information no longer cause problems with track names.
• A drawing issue has been resolved involving drum maps with note data outside their drum map parameters.
• Fixed a problem that could cause a crash when deleting a bus from a 5.1 surround sound project.
• Fixed a variety of issues with the Piano Roll Editor caused by dragging files from the Explorer to the ACID timeline.
• Fixed a bug so that MIDI notes selected using the in inline editing mode will play as displayed while loops are being previewed.
• Fixed a bug that could cause a crash when rendering to a new track using M-Audio Ozone with a USB connection.
• In 5.1 surround mode, when a track is routed to a bus, the Surround Master now receives the input monitoring signal.
• You can now pan tracks that are routed to a bus in stereo and 5.1 surround modes.
• Fixed a bug so bus levels are preserved after selecting Undo after a bus has been deleted.
• Fixed a bug that grayed out VSTi sub-busses when the main bus was muted.
• Fixed a bug that caused audio to stutter or drop out entirely during playback after UAD-1 effects had been added to the project.
• Fixed a bug so that busses are renamed to their default names when a new project with busses is opened using ACID's default settings.
• Various improvements have been made for using ACID as a ReWire device.
• Fixed various VSTi window sizing issues.
• Added program change maps for the Korg Karma, Korg Triton rack (system version 1.52), and E-mu Planet Earth.
• Resolved an issue so audio and MIDI ports remain open when focus is lost and the Preferences pane is open.
• You can now undo a key change to a MIDI clip.
• Fixed a bug that could cause ACID to hang when adding keyframes to 5.1 surround projects.
• Fixed a bug that could cause a crash when you import MIDI files with no note data into your project.
• Fixed a bug that prevented NI Akoustik Piano, E-mu Emulator X, and Proteus X from loading properly.
• Resolved two issues regarding undoing MIDI program changes:
  • Undoing a MIDI program change now updates MIDI drum maps with the proper settings.
  • Undoing a MIDI program change now updates MIDI devices or soft synths with the proper settings.
• Fixed a bug that caused audio glitches at the start of playback in a project with two MIDI tracks routed to a DLS soft synth.
• Fixed a problem with incorrect event clips caused by removing unused clips and then selecting Undo.
• Resolved an issue so that you have the option of choosing any audio editor that is configured and not just the first one listed under the Tools menu.
• Implemented key support for MIDI clips. You can set a MIDI clip's key on the Clip Pool tab of the MIDI Track Properties window. A clip's key affects playback and now notes are drawn in events.
  • When you create a new MIDI clip, the key is set to None.
  • When you open a MIDI file, ACID will set the clip's key based on the MIDI file. If a clip contains key changes, only the first is used.
  • When you open a MIDI file as a project, the ACID project key is updated to match the MIDI file.
  • When a clip's key is set, the project key and key change markers are applied to MIDI clips. MIDI notes in events are drawn as WYSIWYH (what you see is what you hear).
• Implemented various optimizations for memory usage and performance.
• Improved performance for ASIO drivers that do not notify host applications of buffer-size changes.
• Improved handling for MIDI track, clip, and event pitch-shifting.
• Clip names in the Clip Pool window are now updated when clips are saved to new file names.
• Fixed a bug that prevented arming multiple MIDI tracks for recording.
• Fixed a bug that could cause a crash when renaming an unnamed clip in the Clip Pool.
• Fixed a problem that could cause MIDI clips to drop notes during looped playback.
• An issue has been resolved that prevented FXPansion BFD MIDI files from being added to the ACID timeline.
• Fixed a bug that could cause a crash when changing the channel of a track routed to a ReWire device.
• Fixed a bug that could cause a crash when closing Reason when in use by tracks in your ACID project.
• Fixed a problem that could cause a crash when playing back with certain audio plug-ins (including Antares Filter and Sony Pitch Shift).
• Fixed a problem that could cause a crash or hang when using the Undo command after MIDI step recording.
• Fixed a problem that could cause a hang when arming an audio track for recording while recording MIDI data.
• Fixed a problem that could cause NRPN and RPN MIDI data sent to the DLS soft synth to respond incorrectly to pitch bend or controller data.
• Fixed a bug that could cause dropouts when routing a multichannel VSTi's outputs to a bus other than the Master bus.
• Fixed a bug that could cause dropouts or timing irregularities when routing a multichannel VSTi to a non-in-place plug-in (such as Time Stretch, Pitch-Shift without preserving duration, and some Vibrato settings).
• Fixed a problem that could cause the MIDI Step Record dialog to remain active after canceling step recording.
