- Fixed: Pro Tools Automation Thinning Could Sometimes Remove Non-Redundant Breakpoints (Item #100794)
The thinning algorithm could mistakenly classify a breakpoint as redundant

- Fixed: Playback of Surround Panning automation gets "stuck" (Item #100847)
This would only occur when writing automation with a selection highlighted while in Loop Playback mode

- Fixed: Trim Values Could Be Accidentally Written To The Entire Session (Item #100795)
Steps to reproduce:
A fader position in Latch/Trim or Touch Trim could be accidentally bumped while the transport was stopped.
Subsequently leaving Trim mode, or manually coalescing trims would then write that bumped value to the entire track

Requirements
Mac OS X "Tiger" Only

- Fixed: Slow Session Close or Sluggish UI Response Often Followed by a DAE -4 Error, Leading to Pro Tools Unexpectedly Quitting or the Computer Restarting (Item #102166)

Pro Tools® 7.4.2 software provides Mac OS X 10.5.3 Leopard compatibility to Pro Tools 7.4 HD, LE, and M-Powered owners. Pro Tools 7.4.2 software requires Mac OS X 10.5.3. If you have an earlier version of Leopard, you will need to update your Mac OS using the Mac OS X 10.5.3 Combo Update before installing Pro Tools 7.4.2.

- Added: Expand to New Tracks by Time Code Only (Item # 102582)
The new Expand To New Tracks By Time Code Only feature lets you expand a track or selected region to new tracks, revealing all other regions recorded at the same time code location, regardless of channel name or number.

- Background
This feature is useful when expanding edited guide tracks to original source audio which was recorded while referenced to time code, but channel names or numbers were not written to the audio files. For example, when a live concert is recorded in Pro Tools, then a guide audio track is edited along with the video, then the edited guide track is returned to Pro Tools and needs to be expanded to the original source tracks for mixing.

- Additional Information
Please see the "Expand to New Tracks by Time Code Only Read Me", included with the update and available separately below for important additional information, including:
Typical Workflow
Relinking the Original Unedited Guide Track
Known Limitations with Expand to New Tracks by Time Code

- Fixed: DigiBase Aborts Cataloging if Audio File Comments Exceed 256 Characters (Item #100604)
When attempting to catalog, a Neo Assertion error appears in the Project Browser
The following error is generated when selecting a 256 + comment in the Workspace: "The value contained too many characters; previous value substituted".

- Fixed: WAV Files Containing Non-English Characters Are Not Visible In Pro Tools 7.4, and Can Be Corrupted if Edited (Item #100502)
Although the file comments are invisible in the DigiBase comments field, clicking in that field will delete all of the comments
This only affects non-BWF WAV files
This CS version restores the visibility of WAV file comments, as long as the field wasn't clicked in using earlier versions of Pro Tools 7.4

- Fixed: Only the First 16 MIDI Inputs Are Available In The MIDI Input Enable Window (Item #76712)
Window cannot be resized, scroll bar doesn't access other MIDI inputs

- Fixed: Trim Values Could Be Accidentally Written To The Entire Session (Item #100795)
Steps to reproduce:
A fader position in Latch/Trim or Touch Trim could be accidentally bumped while the transport was stopped.

The thinning algorithm could mistakenly classify a breakpoint as redundant

- Fixed: Certain Third Party Products Could Cause Pro Tools to crash (Item #100661)
Celemony Melodyne and AudioEase Snapper would cause a crash with tick-based regions (introduced in Pro Tools 7.4)

- Fixed: Mojo - PAL QuickTime or MXF Movies Could Stutter or Display in Black and White (Item #101047)
This resulted from Mojo getting "stuck" in NTSC mode even when Pro Tools was set to PAL

This problem was intermittent, and would not occur when using TDM versions of Dynamics III

- Fixed: Surround Pan Automation is not Updating Properly in Loop Playback (Item # 85802)
The pan positions are correct on the first play of the selection, but can be incorrect on subsequent plays
Please note that there is still an outstanding issue where Surround Pan automation may stick on a particular output. Digidesign is currently working on a solution.

Transients could be placed either before or after grid lines

- Fixed: User Can Only Promote the Confidence of an Event Marker by Moving it (Item #100378)
Clicking on any Event marker will now raise its internal confidence rating to 100%, thus preventing the marker from being removed when the Event Sensitivity setting is lowered within the Elastic Properties window

- Fixed: Using Render or Commit With "Rhythmic" Algorithm Can Produce Artifacts at End of Files (Item #100420)
This would usually occur when using extreme amounts of stretching

- Fixed: Elastic Time Warp Markers Could Move After Quantizing (Item #100423)
Quantizing a selected area could cause markers outside that selection to move

Requirements
