Note: the macOS 10.15+ macOS download is notarized and uses the "hardened runtime," which may reduce compatibility with certain plug-ins. You may still run the regular 64-bit macOS download on macOS 10.15 - macOS 12; however, you must shift+right click and choose "Open" when running that version for the first time.

REAPER 6.45:

  • do not allow export_buffer_to_project() to be called from @slider
  • allow override of refresh rate using options:gfx_hz=60 etc
  • add options:gfx_idle to allow @gfx section to run when UI is closed (detectable via gfx_ext_flags having 2 set)

  • add option to close item notes window on enter key
  • save item notes when closing item notes window via action

  • add CalculateNormalization function
  • do not apply render-config changes when calling GetSetProjectInfo in get mode on rendering configuration
  • do not defer indefinitely when calling reaper.defer() with no parameters from Lua

  • fix files left open when normalization/limiting is interrupted
  • fix render peaks display when normalizing and negative project start time offset exists
  • fix saving of presets with normalize enabled affecting old presets
  • add "erase" as a default synonym for delete/clear/remove
  • do not warn on program startup if too many custom actions exist (only warn when creating)
  • add per-theme option to not use themed window colors when in dark-mode (enabled by default theme)
  • improve performance of Live FX multiprocessing, especially on M1 systems
  • improve behavior relating to project notes flags and loading projects in REAPER 6.38 and earlier
  • on new project without saved project settings, set recording/render format to 24-bit wav
  • fix extra sine oscillator when portamento is used
  • fix stuck note when portamento is used in certain instances
  • fix recording glitches that could occur during looped project-synchronized playback
  • support exporting media into project via MIDI CC when UI is not open
  • fix listview drawing glitches when editing values and scrolling
  • support very long pathnames (note: for shell browsing/etc to work with these, the LongPathsEnabled registry key must be set)
  • improve display responsiveness of progress bars
Control surfaces
  • fix CSURF_EXT_SETSENDVOLUME notifications when in write mode and fader-scaled envelopes
Custom action editor
  • fix entering certain characters on macOS
  • if format supports BWF, write start offset when exploding multichannel audio to new files

Razor edits
  • do not delete/cut/copy razor edits when cursor focus is on track control panels
