Pre-release version 6.3.8 of Metro is now available.

New:

• Virtual Instruments (VI's) can now have their audio volumes and pans automated. A new display mode of the graphic editor allows the selection of audio volume and audio pan for VI track types.
• Metro now finds MIDI input devices even when their uniqueness changes. This works around a bug in MIDIkeys.
• MIDI track input selection is much more versatile. Any combination of MIDI channels can be selected on input with the new submenu popup in the tracks window.
• Metro now defaults to Apple's generic Audio Unit interface if the plug-in does not have one. This is configurable on a plug by plug basis in the plug-ins window.
• The audio fade dialog has been improved.
• A remote control preset for the M-Audio Axiom controller.

Fixed:

• Cosmetic problem when Mixer window was sized too small.
• Problem with data ranges in the continuous data display of the graphic editor.
• Bypass automation was not limiting its values to just on and off.
• MIDI data was not being drawn underneath continuous audio volume and pan for Virtual Instrument tracks.
• Better stability.
• Improved CoreAudio reliability.
• Removed an annoying flash that was occurring on open and new when transport was floating.
• The continuous data dialog was not displaying the title of the select data correctly in some cases.
• Selecting float transport window from the switches menu while the transport was not visible would cause the transport to not redraw correctly in some cases.
• Initial import of audio was not extracting the tempo from the audio file in 6.3.7.
• If an input audio port was out of range no error message would occur until recording in some cases.
• Recent plug-ins could mysteriously disappear in some cases.
• Automating pan was excruciatingly slow in some cases.
• The countoff was counting 1/2 as long as it should in some cases.
• Minor correction when automating Audio Unit parameters.
• Better support for automation only tracks.
• Certain Audio and MIDI tracks were not being muted properly during record.
• A problem whereby Metro would try to close a non-existent CoreMIDI connection if a selected record MIDI device recently came online.
• Undo of record now properly restores the select track range.
• Jukebox now correctly parses the full OS X file name.
• Old Rhythm Explorer presets now default to staccato = 50% instead of 0.
• In some case recording audio through a plug-in like 'Apple:Pitch' would not initially playback properly.
• The contextual tracks window output menu would not always show the correct connection if a track was frozen.
• Clicking on the tempo door of the transports more than once was causing a problem.
• Selecting 0 in the scale time dialog could cause a crash on Intel Macs.
• Scale time would not always set the track length appropriately.
• Using return when in 'editing mode' no longer moves the graphic editor display.
