Cockos has updated REAPER to v3.4.

Changes:

• MIDI editor:
  • Action to show raw MIDI data.
  • Better drawing/editing for CC events that occur at the very end of the item.
  • CC lane marquee selection, drag or copy selected CC events.
  • CC lane context menu (select/unselect all events in lane, nudge events, etc).
  • Correct overlapping notes whenever they occur.
  • Ctrl+drag to resize one CC lane only, shift+drag to accordion all CC lane sizes.
  • Finer control of mousewheel vertical zoom.
  • Fix for resizing notes up to the left or right edge of the parent item.
  • Fixed marquee selection for drum-mode notes.
  • Fixes for vertical zoom when user preference is to center on mouse cursor.
  • Improved event list properties dialog.
  • Many actions apply to all selected note and CC events.
  • Preferences for sweeps/ramps to affect only selected CC/velocities.
  • Preserve CC event selected/unselected state.
  • Remove CC events with duplicate times and the same status/channel.
  • Support clipboard copy/paste between piano roll, event list, and some external applications.
• OSX:
  • Preliminary bridging support (to run 32 bit plugins on 64 bit, PPC plug-ins on Intel, etc).
  • ReWire slave support (enable slave mode in prefs/plug-ins/ReWire).
  • Audio Units: bridging/firewalling support, with per-FX options (similar to existing VST bridging).
  • Audio Units: pass through REAPER key commands shortcuts when plug-in GUI is focused.
  • Audio Units: more consistent GUI updating when playing back FX automation.
  • Audio Units/VST: enable text entry in edit fields, pass through other keystrokes for Carbon-based plugins.
  • CoreAudio: improved samplerate changing, detect changes on the fly and reinit device.
  • 64 bit version is now named REAPER64.app, better .dmg labels (shows arch).
  • Improvements to plug-in loading code (fewer crashes when plugins are missing dependencies).
  • ReaNINJAM: better support for removing / readding VST.
  • Spawn new REAPER instance is now supported, basic command line option support.
• Ripple editing:
  • Better behavior moving items left/right followed by up/down.
  • Better behavior when moving items left (configurable in prefs/editing behavior).
  • Better behavior when using ctrl+drag copy of items.
  • Fixed ripple all moving via action, with locked items affecting rippled markers.
• Windows:
  • Better handling of ASIO reset messages when project samplerate is set.
  • Fix for unicode characters in new Vista+ file open/save dialogs.
  • Prevent errors on audio devices that display error messages via MessageBox.
  • Vista+ file dialog for source properties and save track template file dialogs.
• Multi-touch:
  • Windows 7 and OSX 10.6 multi-touch gestures can be mapped to REAPER actions.
  • Per-gesture options for reverse, scaling, disabling inertia, improved zooming.
• Resampling:
  • Fixed resampling for media of more than 32 channels.
  • Internal checks to behave better when out of memory/address space.
  • Decreased RAM use in higher quality modes.
• VST:
  • Fix for occasional dropped keystrokes that are meant to be passed through to REAPER.
  • Internal scanning/resolving tweaks.
• Action: adjust last touched FX parameter (mousewheel/MIDI CC).
• CPU usage: optimizations with high track counts (solo sibling calculation caching).
• Elastique: updated to v2.12 (fixes x64 quality issue).
• Envelopes: preference for double-click to add envelope point, or reset existing point to center.
• Item properties: better-looking fadein/fadeout menus.
• MIDI controllers: fix for occasional disappearing action mappings.
• Mixer: save/restore exact visibility of FX, FX parameters, and sends.
• Mousewheel: enable relative zoom for mice that send finely-grained mousewheel data.
• MP3: fixed poor quality render with VBR encoding on OSX and Windows x64.
• Preferences: save/restore last preferences page visited when closing/opening REAPER.
• RAM usage: drastically reduced memory use when drawing waveform peaks in certain instances.
• ReWire: workaround for Pro Tools crashing on exit when REAPER is ReWire slave.
• Tempo maps: lower CPU use for projects with large tempo maps (helps VST time info as well).
• x64: support bridging/firewalling of x64 VSTs, including 32-bit REAPER in WoW64.
• x86/x64 bridging: internal improvements and bugfixes.
