Here's what they say:
Tantra (Sanskrit: तन्त्र; literally "loom, weave, system")
Weave is a 65 preset expansion pack for Tantra showing its ability to introduce a huge range of movement, rhythmic glitches and complex modulated craziness to any kind of audio. Weave's patches make use of all of Tantra's effects and modulators in various combinations from dub delays, vast reverbs, mild enhancement of pad sounds to total destruction of drum loops and everything in between.
The patches are named for their intended use – DruM, PAD, EFX (general effect), FLT (flter) etc. but some great effects can be achieved by 'mis-using' the patches so go crazy and try everything on everything and see what happens.
Weave is available now for $15.
