Umbra Free is basically a Waveset of 128 complex waveforms as SF2 plus a specially designed VSTi Synthesizer / SF2 (Soundfont) player.

The Umbra waveset consists of complex waveforms which are best suited for dark ambient, soundscapes, athmospheres, textures and rather experimental sounds.

The Umbra waveset can be used also with STS-26 and ProtoPlasm21 though it is recommeded not to load it into all slots of these as sound might get too fat then.
