How do you change kHz on Pro Tools?

If you’re getting a Pro Tools error message that starts with “The current playback engine does not support a sample rate of…” or having troubles due to a sample rate mismatch, you likely need to change the Playback Engine or change the sample rate in Pro Tools. You can solve both of these issues two ways:

• Change the Playback Engine in Pro Tools
• Change the sample rate in Pro Tools

Change the Playback Engine in Pro Tools

One way to potentially solve this issue is to change the Playback Engine (interface) in the settings:

If Pro Tools opens

Dismiss the message and open the Setup menu, and select Playback Engine. Then, change the Playback Engine in Pro Tools from the drop-down menu to your interface.

If Pro Tools launches, change the playback engine in the preferences.

If Pro Tools doesn’t open

Launch Pro Tools and hold the ‘N’ key as soon as you see the Pro Tools splash screen. This will allow you to select the Playback Engine before Pro Tools tries to initialize it.

If Pro Tools doesn’t launch, Hold ‘N’ while Pro Tools is loading.

Change the sample rate in Pro Tools

Before you launch Pro Tools, you will need to go to your system sound settings and verify that the sample rate matches that of the project. However, since there’s no way to change the sample rate in Pro Tools directly from the project, you can create a new session and import all of the current project’s data at the desired sample rate in Pro Tools.

1. Navigate to File, select Save As, then choose a name and location for your project.
2. Close out of that project, then create a new one at the desired sample rate.
3. With the new project open, navigate to File, select Import, then choose Import Session Data.
4. Navigate to the location where you saved your project, select it, then load it. 

Still getting the error?

If you still get this error or if your playback engine was already set correctly, make sure you have the latest driver installed for your interface. Also, make sure your system sound settings aren’t using the driver for your interface, which will often cause this error. Also, be sure to check out our guides on how to trouble audio interface issues on PC and Mac.

Yes look at the menu item under "File" named "Save Copy As..." and look over the options there. You can tell it to make a copy of the complete session with all the audio files converted to your target rate/bit depth. I would recommend saving the copies in a separate location on your drive to save yourself from confusing the new files with the old. Since it sounds like most of your work is in midi, the size of these new sessions should all be pretty small, but for the record there's no way to just switch the sample rate over in a session once it's been created. If there's really NO audio in any of the sessions, then maybe it would be OK to keep all the files in the same place and just relabel the new session as being at the new rate.
