REAPER 7.37

What's new in this version:

Render:
- support preview playback of rendered files
- 'tracks with only mono media to mono file' considers take channel mode and channel mapper but not per-take FX
- add preference to enable actions to open statistics for most recent render in web browser after the render window has been closed, to save memory if the user does not need this feature (statistics can always be saved automatically or opened directly from the render dialog)
- add preference to suppress prompt to save/delete incompletely rendered files
- add render postprocessing help
- add render setting to enable parallel render via master, with info button to explain behavior
- after canceling incomplete render, prompt the user to save or delete the partially rendered output files
- apply postprocessing fades before start/end padding
- automatically select the rendered file in the statistics list view when automatically changing peaks display
- display file length in hours if appropriate in render settings file list dropdown
- fix potential crash when editing razor edit areas while render settings dialog is open and configured to render razor edit areas
- if possible, postprocess each file immediately after rendering
- if rendering to more than 2 channels and 'multichannel tracks to multichannel files' enabled, tracks with fewer channels do not override the render channel setting
- improve render speed with various combinations of postprocessing settings using multithreaded processing
- only support $item wildcard when rendering selected items
- support adjusting mono media by +/-3dB regardless of whether normalizing is enabled
- support changing previewed file via listview keyboard navigation
- support normalizing/limiting/trimming to master mix
- support normalizing and/or limiting each file separately, or as if all files play together
- normalizing as if files play together calculates gain adjustment based on the actual summed rendered output of rendered files
- normalizing as if files play together is similar to the previous setting to normalize to master mix; common gain is applied to files that start and end at the same time
- normalizing as if files play together (common gain) is similar to the previous setting to normalize as if one long file; common gain is applied to all files
- support padding start/end with silence
- support parallel rendering of media items or razor edits on separate tracks if overlapping
- route render playback to master track hardware outputs
- if rendering multiple files at once would overwrite some files, support overwriting all, or rendering only new files and skipping existing files, or canceling
- support rendering selected items or razor edit areas as one file (render master mix, but ignore all non-selected items or all non-razor-edit areas)
- support trimming silence from start/end of rendered files
- update file list display when checking/unchecking "do not render files that are likely silent"

Big clock:
- support $projectpos, $projectlength wildcards in various time formats, including whole measures or beats within measure
- $trackitem resolves to item notes for empty items
- add $masterpeak, $masterloudness wildcards
- add $regionprev, $regionnext, $markerprev, $markernext wildcards
- allow minimum size to be smaller, especially when docked
- display region/marker color indicators inline with text
- double-click anywhere in the window to open customization dialog
- double-click on resolved $rectag or $recpass wildcard to set new value
- respect setting to overlay (or not) beat count over visual click background image
- scale custom visual click background image to fit beat display area
- support up to 8 rows of wildcards
- update display when loading/unloading visual click background

MIDI editor:
- fix note folding when switching contexts and selection linked to visibility/editability
- use project grid setting for grid line minimum pixel spacing
- follow visible grid preference when inserting grid-size notes
- improve painting note behavior with visually-reduced grid
- improve edit cursor behavior in Source Beats timebase
- improve maximum horizontal zoom range
- improve snapping in source beats view
- improve scroll positioning when switching between items in Source Beats timebase
- preserve editor configuration when gluing items, recording to new items on a track, etc

Actions:
- add 'Insert new track as first track', also add support when using insert tracks dialog
- fix dry run render time display in actions to calculate media item loudness
- fix moving cursor right to grid line when using Metronome grid and 2x/4x multiplier
- improve behavior when inserting a new track via mixer and collapsed folders exist
- prevent opening multiple copies of dialog to set recording tag or recording pass counter

Wildcards:
- allow wildcard help window to stay open
- deprecate $namenumber, use $filenumber or $recnumber instead
- fix $markername/$regionname wildcards
- fix '$markernumber[N]', '$regionnumber[N]' when no previous marker/region exists
- reorganize wildcard help categories

Actions window:
- support adding keyboard shortcuts via context menu
- prompt to overwrite existing shortcut bindings prior to closing window

Batch converter:
- use media item position in project when converting media items and preserving metadata start position
- when trimming leading silence and writing metadata preferred position, adjust preferred position after trimming

MP3 decoding:
- allow configuring threshold in megabytes where .reapindex file will be used for VBR files, via reapindex_minsize in reaper.ini (default is 12000000 bytes)
- optimize opening files with CBR LAME tag

Take FX:
- fix incorrect flushing of PDC plug-ins on second playback (7.36 regression)
- only auto-extend item tail for take FX that report infinite tail if FX has automatic tail detection enabled (7.36 addition incomplete)

Fixed lanes:
- fix unnecessary lane creation when recording starts immediately after a previous recording

FX:
- optimize performance of FX embedded in the MCP

Localization:
- localize 'mono', 'stereo' in render channel dropdown

Loudness:
- calculate LUFS-I even when the signal is very very loud

macOS:
- fix MIDI-learn and other things not working properly when modal UI created from deferred ReaScripts

Meters:
- adjust dB number positioning to account for gain reduction meters

Mixer:
- improve layout with very narrow mixer window

Normalize action:
- fix potentially inaccurate LUFS-I calculation when normalizing multiple media items as if one long item, some items are mono and some are not, and mono adjustment is enabled

Preferences:
- move meter dB scale options to theme-specific settings, set via theme tweaker

Razor edits:
- fix razor edits on collapsed fixed lane tracks not respecting option to not affect all lanes

ReaScript:
- document gfx.mouse_cap modifier key flags for both Windows and macOS regardless of which OS the documentation is generated on

- fix layout issues relating to gain reduction metering in certain instances

Track/region/marker/group manager:
- fix committing renamed row when immediately double-clicking to rename another row
