Some of my findings, perhaps double;
Some ligos indeo XP 5.2 files don't play, they do preview though?!
Effect parameters active channel. don't react (midi) on selection, when viewing propeties it does work, but that's insane
update of preview is also corrupted.
Scrolling in directory's doesn't work!
400x300 processing, 640x480 output seems to crop the image somewhat (seems 640x400)
Lots of freeframe plugs seem to be instable.
a small list, great update, when will a new beta be out? Seems wise to let the users do another test-run
