Digital Audio Record Buffer Size and Number Specify the number of bytes you would like allocated to the Digital Audio Record buffer. Metro’s default Record buffer size is 60 kilobytes. Experiment with a higher Record buffer size if you experience troubles recording audio into Metro. Sometimes increasing the number of buffers, rather than their size, improves recording performance. Try increasing the default value of 4 to 5 or 6. SysEx Buffer Size Digital Audio Playback Buffer Size See Also: Audio Performance Tips and Troubleshooting General Preferences Timing Preferences
