Update: The x86 installer contained three old plugins that i used for testing.
If you have downloaded it already, delete these three files: arguru-synth-2f-old.dll, legasynth-303-old.dll and maeq-old.dll. I've uploaded an updated installer with these three files removed.
There's a new beta version for the next release.
This beta contains mostly a couple of bugfixes in the main program and updates in most of the effect plugins and some native instruments.
Concretely, legasynth sounds much better now and fluidsynth has been updated to version 1.1.2.
Also, sound skip in Vista and 7 should be reduced, thanks to usign the new thread priorities defined in these new systems.
Oh, and there's the suggestion for the interpolate curve asked in the psycledelics boards :)
