Changes in 0.18.5 (relased 28/10/22):
* Target sound filename shown (and tells you if you don't have one)
* More soundfile formats supported (aiff,aifc,au,snd,fasttracker xi,flac)
* New configurable OSC ports in settings
* Warning boxes if the OSC network connection fails
* File path memory per-dialog rather than global
Changes in 0.18.4: New audio device settings window and updated
windows build. Better default block size, tool tip tweaks and fixes
