Cockos updates REAPER to v4.20

Cockos has updated REAPER to version 4.20, which brings substantial new functionality to the 4.x series.

Changes in Version 4.20:

• OSC:
  • control surface support.
  • default REAPER-specific controller specification, plus user-configurable pattern mapping.
  • optional support for binding OSC messages to REAPER actions and FX learn.
  • please see the REAPER OSC reference for more information.
• Localization:
  • localization support (see the REAPER langpack reference for more information).
  • configuration (prefs/general) for language pack selection, optional prompt on startup.
• MIDI buses:
  • now supporting up to 16 buses per track (main bus and 15 auxiliary buses).
  • track send panels allow choosing source, destination buses.
  • bus support for VST/AU/ReWire, JS (to use in JS, set ext_midi_bus=1 in @init, then midi_bus is used for bus indices).
• API:
  • many new functions for FX presets, open/close UI, bypass, sends/receives, tempo.
  • many new functions for control surface support, scroll/zoom, track visibility, mixer scrolling.
  • access media item text notes via GetSetMediaItemInfo().
  • register OSC clients for 2-way communication.
  • GetSetObjectState() locking improvements for less audio interruption.
• Freeze:
  • better subsample alignment of frozen items.
  • by default only the media items plus FX tail length setting are rendered, with options for other behavior.
  • fixed possible undo corruption of freeze states after reordering tracks.
  • fixed warning when unfreezing after editing frozen track.
  • freezing tracks clears track polarity, unfreezing restores.
• OS X:
  • fixed focus-related issues when setting default text selections.
  • fullscreen mode auto-hides menu, hides dock on 10.6+ (pref to auto-hide dock in prefs/general/advanced).
  • possible stability improvements in certain instances (IsWindow() improvements).
  • compatibility fixes for Mountain Lion beta.
  • show error and keep device closed when unable to open a CoreAudio device.
• Glue:
  • avoid leaving tiny shards of items in certain instances.
  • use audio device blocksize for better compatibility with take FX.
• Item properties:
  • option to apply changes after 2 seconds of inactivity.
  • fixed normalization outside of fader range via normalize button.
• JS:
  • fixed possible crashes on preset load with pin mappings set.
  • fixed preset saving for JSFX that use @serialize.
• Media explorer:
  • preliminary media database support (right click in shortcut list to create/manage databases).
  • native view remembers column widths.
  • support for binding MIDI/OSC to media explorer actions.
• MIDI editor:
  • fixed actions to move notes one semitone when hiding note rows and snapping to scale.
  • fixed swing grid when using odd time signatures.
• MIDI file import:
  • fixed bug when importing tempo maps with frequent tempo changes.
  • properly handle snapping odd-numbered 8th-note time signatures.
• Pitch shifters:
  • reduced excessive flushing/improved performance on certain items.
  • workaround for Elastique quality bug when using very short items.
• ReaScript:
  • added function to send a simple OSC message to REAPER.
  • increased maximum returned string length to 4MB.
  • special Python handling for GetAudioAccessorSamples (support examining audio samples directly).
• ReaTune:
  • fixed overlap for offline analysis, other improvements.
  • removed buffer mode configuration; PDC is always used when correction enabled, not used otherwise.
  • when in analysis-only mode (tuner), offload processing to GUI thread for better performance.
• Record input menu:
  • support for assigning inputs for all selected tracks.
  • support for assigning sequential inputs for selected tracks.
• Region manager:
  • avoid autoseek when selecting multiple items, clicking color/render columns.
  • selecting a marker/region scrolls it into view, if option enabled.
• VST:
  • bridging now supports SysEx to/from plug-ins.
  • fixed support for plug-ins with more than 64 inputs or outputs (Halion4).
• WALTER:
  • added new theme images master_mcp_io and master_tcp_io for master track.
  • added trans.sel.color, trans.curtimesig.color, made trans.rate.color affect both rate label and rate text.
  • fixed some overlay redraw issues.
• Actions: support full continuous controller range for actions to set track FX parameters.
• APE: no longer including APE support in REAPER, separate download will be available for Win32/Win64.
• AU: support for generator AUs (such as AUNetReceive).
• Custom action editor: faster list updating when filtering.
• Dynamic split: prevent creating MIDI notes with velocity more than 127.
• FLAC: fixed seeking after error on FLAC files, fixes problems where FLAC drops out in certain instances.
• Freeze/Render: better behavior when rendering multiple files.
• Input FX: fixed glitches when looping.
• Item fades: right-click to change fade shape applies to all selected/grouped items by default.
• List views: show arrow in header to indicate sort column and direction.
• Live FX multiprocessing: slight performance improvements when using large track counts.
• Master track: save custom master track color with project.
• Media items: improved consistency of fade and item edge timing.
• Memory warnings: better default values (32 bit on Win64/OS X have higher defaults).
• Mouse modifiers: fixed autoseek on click when left-drag customized to marquee select.
• Performance meter: optimizations.
• Preferences: fixed changing default project template.
• Project load: can be aborted on memory warning or missing media.
• Reasamplomatic: improved support for UTF-8 filenames.
• Render dialog: improved focus setting on open.

• Track/region manager: fixed color display bug.
• Undo: improved updating of various views when loading undo states via history.
• VST/AU: ensure that full FX state is saved with projects/templates.
• WAV writing: support for embedding cues from project markers, regions, or both.
