Version 1.1.0 won't be compatible
with earlier versions but 1.1.0 can be installed
alongside previous versions if one of the plugins is
renamed. Since the amount of controls isn't too high
migrating shouldn't be a problem.
ReFine is a plugin that allows to
add a final polishing to your tracks, busses and
masters. It extracts psycho-acoustic parameters from
the source and thus allows to add warmth, space and
punch to your mixes. This is done level dependent
and rather subtle; you probably won't be able to
create heavy distortion effects with this plugin.
The plugin is now open source.
