Pre-release version 6.3.7 of Metro is now available.

New:

• Metro makes vastly improved usage of available CPUs with the new core audio option 'Thread Priority'. The setting of 'none' is what all previous OS X versions of Metro used. Metro now defaults to 'medium'.
• Metro LX supports up to 24 audio tracks now and 24 effects (or 6 synth plug-ins) simultaneously.
• Typing in numeric values in note fields is now acceptable. For example, 60 = c3.
• The duration dialog has been rewritten to be more OS X like.
• A new View type of drum editor, Drum Bars, has been added to the view menu. Documentation on this is forthcoming.
• Option-clicking on a drum solo button clears all solos.
• Importing sysex from a .ins file now sets the sysex event name.
• Intel Mac optimizations. Including automatic disabling denormalization in the audio engine.
• Using an aggregate audio device no longer results in long delays when play is pressed (in most cases).
• Intel mac and improved ReWire support.
• Direct support for Logitech mice with horizontal scrolling.
• OS X dialog when the demo versions time out.
• The bank selection in the graphic editor follows bank selections sent through MIDI thru.
• Expand is now possible without stopping play back.
• The Notation engine is now lazily initialized. This means if the Notation or Lyrics window is never opened, significant memory resources are conserved.
• The currently playing jukebox entry is now denoted with a red triangle.

Fixed:

• The master fader's clip indicator is now working.
• Automation record now works on empty tracks.
• MTC sync is now fixed.
• AU plug-ins output re-configuring has been improved.
• A possible crash could occur when attempting to transpose an audio track that contained no data.
• Pressing stop while recording the Ultra Rhythm Explorer might not record the last pattern change.
• The Ultra Rhythm Explorer has been improved including new preference field for legato/staccato and a new variability slider.
• Insert Random Chord Progression has been vastly improved.
• The Contextual menu showing the track, mixer, effects and graphic edit windows output routing has been improved.
• Inserting time could cause events to become temporarily out of order.
• A bug introduced with sample accurate AU automation, was sending bogus data to certain AU plug-ins during automation play back.
• Pasting audio data onto a pure MIDI track is now impossible.
• The Metronome port setting is now retained across Metro sessions.
• The Metronome was not playing properly if assigned to a soft synth.
• Improved internal Metronome support.
• Soft-synth could play extra data on the last loop iteration if independent track looping was enabled.
• Dragging a plug-in to a graphic editor slot was not always loading the plug-in on the selected track of that slot.
• Using the contextual menu item 'To Track' in the plug-ins window used to place the plug-in on a new track but now places it on the currently selected track.
• Upon loading of a Metro document the order of plug-in windows was not being restored properly if the transport was in a different floating state than when the document was saved.
• If the jukebox was front most when a document was opened it was possible that the transport would disappear.
• Opening older Metro program name documents was failing on Intel Macs.
• The default controller (or plug-in parameter) was not being endian swapped and thus would not work when a document was transferred PPC to Intel or visa versa.
• Importing a type 0 MIDI file did not always set the track type to MIDI.
• Importing Quicktime MIDI files did not add the files to the recently imported MIDI files menu.
• Certain real-time operations would set the play position of soft-synths incorrectly.
• Creating notes, via chord mode or insert chord progression, on a bass track will automatically lower the notes one octave.
• The change port dialog has been improved.
• The velocity algorithm in groove quantize has been slightly improved.
• Pasting past the end of track in real time now sets the track position correctly.
• Mousing numeric fields has been slightly improved.
• Independent track looping has been improved and is no longer dependent upon MIDI data existing.
• The bar, beat, clock readout in the graphic editor no longer is quantized based on the note edit quantize setting until something is dragged.
• The glitch dialog no longer pops up after quit has been selected.
• On older systems it was possible that the G4 vector unit would not be recognized causing Metro to quit even though it was running on a G4.
• Pressing the 'esc' key while Metro is loading causes it to stop searching for plug-ins. Previous to this version it would also permanently remove items from the Graphic Editor's plug-ins menu.
• Better ReWire error messages.
• Since 6356 certain windows would not be deactivated properly.
• The cursor changes more appropriately in the drum editors.
• Miscellaneous cosmetic improvements.
• Dragging at the sample level has been improved.
• The internal Metronome is improved when syncing to MTC.
• Improved plug-in support.
• VST Automation has been improved.
• A crash could occur when loading a plug-in with an odd number of outputs (> 1) on a track.
• Metro no longer sends the selected bank select message more than once when looping.
• The Ultra Rhythm Explorer Phrase Arpeggiator algorithm has been substantially improved.
• The find program dialog has been improved.
• When attempting to apply an offline effect on an Audio + MIDI track, Metro would erroneously report that no audio tracks were selected.
