Cockos has updated REAPER to v2.51. The Windows x64 Beta and Mac OS X Beta versions have also been updated.

Changes:

• JS: new development environment with editor, debugging support (variable watches).
• Saving track templates now saves any track media items as well (since people seem to want this).
• Loading track templates, fx chains, presets, now prompts for missing media (if REAPER is configured to do so).
• Action: move cursor back or forward one beat or measure, move cursor to start of this or next measure.
• Move to start of current measure action moves back a measure if cursor is already at measure start.
• Create measure from selection actions optionally set project tempo instead of inserting markers.
• REX2: adjust imported slice length to hear the longest tail of previous slices underneath later slices.
• JS: better UI auto-sizing/arrangement.
• JS: MIDI/midi_CC_mapper, updates to spectropaint, added spectropaint_filter.
• OSX: fixed keyboard focus issue on many actions.
• OSX: fixed bug with screensets window (could also affect win32).
• OSX: fixed keyboard state loading bug (required manually removing some key assignments -- could also affect win32).
• Vegas EDL: load/save of fade shapes, lock state, preserve pitch state, loading of mute state.
• ReaSynDr: fixed non-multiout mode.
• Fixed crashes when MIDI files are not found and ignored on project load.
• Fixed project start time offset when rendering cues.
• Fixed FX-add recent search combobox height.
• Fiddly fixes for zero crossing navigation with high frequency content.
