I'm not usually one to start a thread waxing lyrical about software as everyone needs to try it for themselves but I've had a massive amount of fun with it over the last few weeks and I'm sure others would too - its been working wonders for creating scifi atmos or drones, alien creatures, its brilliant on warped engines and for sparking some new inspiration from very normal sounds (clearly you need the right show for it to work on but...). Ribbon controller is a neat idea and a freeze button is always interesting!
If you've ever used the 'effects' impulses in TL Space or like throwing stuff into GRM tools plugs to see what comes out, I think you'll like this one too.
I just discovered this too and I concur. The basic sound of it is wonderful. I haven't even begun using the controllers but they look completely cool. This is not a "realistic" reverb, but as I check it against the new crop of verbs coming out (Valhalla Vintage, Relab LX480) I'm really digging the basic sound of Blackhole more for most things. If you're looking to put interesting spaces in your recordings and not too worried about whether they sound "real," then you should check this out. It's very musical.
And according to the current promotion:
