What’s New
- SoundEditor: three Paste options, namely Paste before selection (Shift-Command-V), Paste over selection (Option-Command-V), and the already existing Paste after selection (now Command-V).
- All editor windows: extended the old single-level Undo and Redo to a ten-level Undo and Redo.
- Scripting: the new runSystem$ and runSubprocess$ return the output of the system command or subprocess.
- Scripting: runSystem, runSystem$, runSubprocess and runSubprocess$ report any error messages generated by the system command or subprocess.
- PointEditor (pulses): settable Period floor, Period ceiling, Maximum period factor and Maximum amplitude factor, for jitter and shimmer measurements.
