Really amazing and unique (at least I don't know of a similar product) delay that does more than just delay. It syncs to tempo, and you get a grid view that allow that allows you to choose which parts of the source content you want to feed through the delay and which parts you don't. The feedback/LFO/Filter section alone is more than worth the cost of admission. I'm just starting to get my head around this piece. I downloaede the free demo, and paid for a license in less than 5 min -- still waiting for a license key in the mail. $50 on sale right now through Audio MIdi .com

Interesting concept; the combination of filters/delay presents a lot of flexibility/creative potential that's seldom explored, and I think the programming here is what makes the product really worthwhile. It would be worth the $50 just to examine and deconstruct those cool presets, imho. Good find, Erich!
