Automation Window Update when Writing Automation (PTSW-46747)
When writing automation on Volume, Pan, and so on, the corresponding buttons in the Automation window provide no indica-
tion that automation on the related control is being written. You will need to observe the automation buttons on tracks in Mix
or Edit windows to see an indication that automation is being written.
Scrubbing Audio is Offset by the Overall System Delay when Automatic Delay Compensation is Enabled (PTSW-150138)
With Automation Delay Compensation enabled, when scrubbing audio the output is offset by the overall system delay (displayed
in the Session Setup Window). Large system delays cause a noticeable offset. To avoid this issue, you can disable Automatic Delay
Compensation when you want to scrub audio for editing.
Possible Performance Issues with Waveform Overviews (110041, 106801, and 106577)
Calculating waveform overviews in Pro Tools 8.1 and higher may cause some one time issues with various operations. Once the
overviews are calculated, system performance will return to normal. Areas where you may notice this are:
• Legacy Sessions (110041)—When opening Legacy Pro Tools sessions (lower than 8.0) for the first time, if you immediately
start playback, you may encounter various errors advising you to increase the H/W Buffer size, or to delete tracks, or to re-
move some Native (RTAS and AAX) plug-ins. This is due to the fact that Pro Tools is re-calculating the session’s waveform
overviews in the background. Pausing this task in task manager, or waiting until this task is complete, will resolve the issue.
Once the waveform is calculated, you will not experience this issue again.
• Playback of Newly Created Clips (106801 and 106577)—You may notice a slight drop in normal playback performance im-
mediately following a record take or after creating or importing new clips. This is due to the fact that Pro Tools is calculating
waveform overviews in the background, and is mostly only encountered when recording or creating many clips with long du-
rations. Pausing this task in task manager, or waiting until this task is complete, will resolve the issue. Once the waveform is
calculated, your session playback performance will return to expected levels.
Waveform overviews disappear after editing metadata from the Workspace browser (PTSW-153258)
If you edit metadata from the Workspace browser, audio waveform overviews may disappear from the Edit window. If this occurs,
recalculate the waveforms or close and reopen the session. To avoid this issue, edit metadata from the Project browser instead of
the Workspace browser.
–9128 or –6031 DAE Errors when Using Sibelius 7 as a ReWire Client with Pro Tools (PTSW-148554 and PTSW-149809)
If you encounter –9128 or –6031 DAE Errors when using Sibelius 7 as a ReWire client with Pro Tools, try increasing the Hardware
Buffer Size to 1024 samples in the Pro Tools Playback Engine (Setup > Playback Engine).
Audio Clips on Tick-Based Tracks Do Not Play at the Correct Tempo after Opening a Reason Song with a Different Tempo
(PTSW-34086)
Audio clips on tick-based tracks do not play at the correct tempo after opening a Reason song with a tempo that is different from
the one in your session. To correct this, make any tempo change via the Conductor track or the Manual Tempo input and the clips
will play back correctly.
Cannot Run Reason or Record as ReWire Clients if They Have Not First Been Launched and Set Up as a Standalone Application
(PTSW-133070)
Reason and Record need to be launched and setup as a stand-alone applications before running them as a ReWire clients with
Pro Tools. Do the following:
• Launch Reason or Record in stand-alone mode and follow the on-screen instructions.
• Quit Reason or Record.
• Launch Pro Tools and insert Reason or Record as a ReWire plug-in on an audio, Auxiliary Input, or Instrument track.
Exporting Interleaved BWF Files from Pro Tools 10 and Importing into Pro Tools 9.0.x and Lower May Cause Pro Tools to Quit
Unexpectedly (PTSW-151579)
When exporting any greater-than-stereo multichannel interleaved WAV (BWF) files other than 5.1 from Pro Tools 10 and then
importing them into Pro Tools 9.x or lower, Pro Tools quits unexpectedly. To avoid this problem, export audio files for import
into lower versions of Pro Tools in another file format (such as AIFF or multi-mono).
