"Girl" is a very odd name for an audio synthesis program, but the description sounds pretty doovy. Basically it's a modular sample-based synthesizer/mixer of sorts, which can apparently work standalone or as a VST plug-in, and can be controlled in realtime using the keyboard or 2D 'plane controllers'; which brings to mind all sorts of glitchy loop-based laptop mayhem. The demo MP3s on the site also sound quite promising, in a
What Is Music? sort of way. Though whether it's worth the A$200 or so it'd cost to register it remains to be determined.
