* If Mac sleeps while playing a music file in the Finder, and then Mac resumes, the Finder may freeze. Here's procedures to recover the Finder:

1. Press command - option - esc keys at the same time.
2. Choose Finder and click [Relaunch] button.
3. The display will indicate "Do you want to force Finder to quit?"; click [Relaunch] button.

* If Mac sleeps while using an audio application, like DAW, and then Mac resumes, playback/recording may not work. If this happens, please relaunch the audio application.

Apple and Roland are looking into these two issues now.
