1 New project, turn audio cache in the Directories Preferences off. 2 Import stereo file (say, 3 minute length) and Edit > Duplicate until you have 64 stereo tracks. 3 Solo some tracks, adjust their gain downwards if needs be and press Play button. 4 There will probably be 10 seconds or more delay before playback starts (more likely to be seen on Windows). Meters will not show playback until a few seconds after audio starts but don't seem to be behind the audio. 5 Press Stop. Audio ceases but meters continue showing a static image from the time playback ceased (or occasionally from a time just after playback ceased) for up to 10 seconds after audio stops.
