Sagan Technology has updated Metro to v6.3.8.6.

Fixed in this version:

• Groove quantize was not working for factory grooves on Mac Intel machines.
• In some cases the continuous data display was incorrect.
• Using the mouse wheel to scroll an unselected pane in the graphic editor would cause the program names field to flash in some cases.
• Vastly improved compatibility with Access Music's Virus TI plug-in.
• Better CoreAudio support for half duplex devices.
• Certain undo operations would not restore the track selection correctly.
• Inserting an event from the section event editor would clear the entire undo history.
• In some cases Mixing audio could be slowed by continuous unnecessary refreshing of the graphic editor.
• Recording of MIDI volume and pan information would fail in some cases.
• On Intel macs only, real time audio track edits would occasionally send a small amount of bad data (big-endian) to plug-ins causing them to sometimes crash, spike or go silent.
• Software audio play-through is now automatically disabled if a direct output is selected.
• On rare occasions it was possible that audio recording could miss a buffer if the thread priority was set to anything other than none.
• A rare crash could occur if there were no MIDI devices.
• The jukebox would incorrectly try to add ID3 tags to .MP4 files.
• Automating on a track assigned directly to a port was creating an automation track with no output assignment.
