Similar in concept to the old Maize Sampler, where you could make a sampler instrument and then save it as a discrete self-contained VST. Also does wavetable, other types of synthesis.
Looks interesting, linux people will be raving - finally a usable free open source sampler on the tux. Might give it a shot & try to compile it if I find myself bored.
Seems to do some things better by design than renoise. It seems to have many features that people are demanding from renoise all the time on these board. On the other hand its dsp seems like not so advanced stuff, no va filters etc.
