If you are experiencing audio dropouts or having notes cut off during playback, it is possible your CPU is struggling to keep up with the demands of the current session. As a workaround, most DAWs offer a way to 'freeze' tracks, which will render the track as an audio file and disable the plugins to conserve CPU. You can later 'unfreeze' the track for further editing or arrangement.
To Freeze Tracks in Logic:
1. Be sure that Advanced Tools are enabled by going to Logic Pro X>Preferences>Advanced Tools and select Show Advanced Tools
2. Control click a MIDI track and select Configure Track Header.
3. Click the checkbox next to 'Freeze'
4. Click the Freeze icon on the MIDI track to render it as an audio file. Click this again to unfreeze the track for further editing.
