Cockos has updated REAPER to v2.55.

• Fixed hang on MIDI bank/program file change.
• Fixed metronome stutter on first downbeat.
• Fixed VST compatibility with plug-ins that send MIDI events from UI/etc.
• Fixed reasamplomatic ui updating bug.
• Fixed render dialog peaks display.
• ReaVerb: lower CPU use, "set all" button for overriding all instances FFT settings.
• ReaVerb: fixed issues with complex chains that convert channel counts.
• ReaPitch/ReaVoice: lower CPU on silence.
• Code to prevent elastique from chewing CPU on near silence.
• FX parameter MIDI learn: fixed updating of "set with selected tracks" flag.
• FX preset loading, VST program changes now add undo points.
• Meta-actions to conditionally process actions based on the sign of CC parameter value.
• Stretching using Elastique by more than a factor of 10 now will result in correct timing but not-fully-preserved pitch.
• mp3 encoder now handles writing mono better (when passed stereo data).
• Existing item selection is cleared when recording stops (recorded items are selected).
