REAPER for Mac

What's new in this version:

Sample edits:
- add action to delete sample edits or set sample edits to zero
- add action to set sample edits to a straight line or an interpolated curve
- allow sample edit scale dialog to remain open while toggling playback, etc
- automatically disable rectified peaks when zoomed-in on items with sample edits enabled
- fix action to set sample values in a straight line when peaks display does not exactly match source sample values
- improve appearance of edited samples when zoomed out
- improve setting sample to interpolated curve
- limit sample edit values to [-1,1], regardless of item volume or pre-FX envelopes
- refresh display after canceling sample scale dialog or bypassing sample edits
- sample edit actions that depend on time selection require the time selection to be entirely on-screen
- support editing sample edits within razor edit bounds
- support editing when peaks display mode is mono or take channel mode is mono downmix (channels are edited identically)
- when running sample edit actions, automatically activate sample edits if zoomed in far enough
- with sample edit scale dialog open, changing time selection or razor edit area changes the target samples for the dialog
