Sagan Technology Metro

New to this version: 6.4.5
- When a plug-in with no inputs (synth) is placed in the middle of an effects chain, the output is now mixed into the chain. This means that layers with some really cool and fat sounds can easily be created simply by placing multiple synths in the same chain.
- Chasing dialog allows an option for chase on record and/or play now.
- The '<', '>', page-down and page-up keys now work in the event editor if it is the frontmost window.
- Improved error handling when an audio device disappears and reappears (usually USB).
- Better VST support.
- New option for contextual plug-in popup, 'Filenames are preset names'. When this option is checked Metro will use the filename (.fxp), instead of the embedded preset name, in its preset popups.
- Faster launch times for those that have many plug-ins.
- New fields in the plug-in window, Discovery (date not channel) and Instantiations (number of times plug-in has been loaded).
- Profiling audio plug-in performance adds the track name or aux number to the printed information.
- Search field in the plug-ins window (The window must be made wide enough to see this field) makes it easy to find particular plug-ins.
- Horizontal scroll bar in plug-ins window.
- Realtime arpeggiator display always moves when enabled.

Fixed in this version:
- Playing notes when the transport is idle now plays the note for the correct duration.
- A plug-in editor window was drawn all white the first time after a document was loaded. This could occur rarely depending on the plug-in.
- After saving a AudioUnit preset, the default preset was wrong.
- Human dialog could set note velocities to zero causing them to not sound.
- Using the arrow keys to shift automation data would cause all automation to be shifted. Now it only shifts the selected data.
- Using command-arrow to decrease duration could, in some cases, cause the note to be changed to a long note.
- Software audio play through now works more consistently.

OS X, version 10.2.8 or higher required.

New to this version: 6.4 (over 50 new features!)
- Mastering. A chain of plug-ins can now be placed on the master causing all tracks and aux busses to process through the chain before being sent to the final stereo output. In the full version of Metro there is now a Master track selection from the tracks popup. The master track has a settable duration, can be looped and can be muted. Muting the master track causes the effects chain to be bypasses which can be useful if you want to addition a recently rendered mix to a track. If an effect is placed on the master buss, the master VU now displays the actual audio signal level instead of simulated audio+MIDI level.
- Side Chains. Metro will now send track audio output or aux buss output to multiple plug-in inputs. Plug-in inputs can be specified by control-clicking the title bar in the effects window and specifying the appropriate source audio. If post is selected the data will be send to the plug-in post fader otherwise it will be pre-fader. For aux buss sources the source is pre-fader only if the aux is feeding data to a lowered number aux buss otherwise it is post fader.
- The number of plug-in's audio inputs can be selected in the effects window (AU only).
- Aux busses can be looped, have a settable duration and can be muted in the graphics editor (full version only). Muting an aux buss will mute the effects chain on that buss.
- The last selected audio sample rate and sample bit size is now saved and restored with the audio device.
- Real-time display of MIDI notes while recording. Since the data is immediately moved directly to the track this feature results in an improved loop recording experience as well.
- Multiple effects in effect chains can now be selected.
- Dragging plug-ins from the plug-ins window to the graphic editor, tracks window or mixer window is now possible. This makes it possible to convert an aux buss plug-in from a track insert and visa versa.
- Strict profiling of plug-ins option in general preferences. This causes Metro to create a report of the timings used by various plug-ins. This report will appear in the system console. This option, when enabled will cause Metro to stop playback if a plug-in uses too much CPU time.
- Effects window GUI rack is complete with new 'Del' (delete) buttons. This new GUI is switchable and can be turned off from the effects window contextual menu popup.
- Effect window plug-ins rack color can be specified by control-clicking the name in the effects window. Colors default to the corresponding specified category in the plug-ins window.
- Effects window contextual menu item 'show in plug-ins' finds the currently instantiated plug-in in the plug-ins window.
- Effects window now has a down pointing triangle allowing the direct instantiation of a plug-in.

- 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 frontmost 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.
