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 Cubase:
1. Click the 'Freeze' icon on the MIDI track
2. Check the Unload Instrument When Frozen box, then select OK.
3. Click the 'Freeze' icon again to unfreeze the track for further editing.
