Sagan Technology has made a new pre-release version of Metro, v6.3.5.4, available for download.

Changes:

• New slider in the jukebox window for setting the current playback position.
• New plug-in option 'configure to stereo output', forces AU plug-ins to use a single stereo output where applicable. This enhances support for MOTU's MachFive plug-in. For users who wish to use MachFive within Metro, please read this important tip.
• Play Quantize has been implemented for MIDI soft synths.
• Some Intel-Mac plug-ins were causing some of Metro's dialogs to display completely white with just an OK button. This has been corrected.
• A crash could occur by selecting a clef in the notation setup track dialog. This time it really is fixed.
• A problem could occur if a document was dragged on the Metro icon while Metro was performing a mix or render operation.
• When saving .ins files, Metro was not including the correct drum sets for soft-synth devices.
• In certain instances, no error message was displayed when a plugin failed to load.
• Dynamically created program names are now correctly loaded for Audiounit plug-ins. This was broken in 6.3.5.3.
• Program name banks are now correctly updated and automatically assigned in the current Metro document after modifications are made via the program names dialog.
• Find program was not working correctly for soft-synths.
• A crash could have occurred when disposing of a plug-in if its interface was visible and the plug-in only existed in the undo history.
• It should now be impossible to click away from the about window and have it remain visible.
• Better .ins file support.
• Miscellaneous cosmetic enhancements to dialogs.
• The note edit event dialog now allows the clock and beat fields to be decremented below zero if possible. For example, assuming a PPQ of 384, if the current duration is 1 beat, decrementing the clock field will set the clock to 383 and the beat to 0.
• Arming and disarming tracks are now undoable.
• A problem whereby clicking in the graphic editor track's title bar could erroneously bring up options when master volume or tempo was selected.
• Better support for AU plug-ins that have updated their type.
• Metro now detects if an open audio file has been replaced in the same folder. This could happen if a user goes to the finder, moves an in-use file to the trash and then places a new file in the original location with the original name. This is not a good thing to do. An error message will be displayed.
• A bug in Rhythm Explorer's recording has been corrected.
