Texture Loom is a free dual-sample atmosphere engine by S1gns Of L1fe, designed for creating evolving pads, drones, cinematic beds, textural layers, and ambient movement from your own audio.

Load two samples, blend between them, shape them with filtering and motion, then send the result into an onboard space/reverb section. Texture Loom is simple enough to start making sound immediately, but flexible enough for slow-burning sound design, generative ambience, and deep sample-based texture work.

Another cool vst from Chris @ S1gns of Life. Just a few random samples creates interesting textures. Trouble is, they just keep on playing. It looks like you have to use the DAW to records the output.
