I'm giving this a 10 because it's super unique. It's basically a delay with an integrated compressor. I'll try to do it justice, but you really should just try it for yourself. I don't know of any other delay that ducks the delay line in favor of the dry signal.
The best thing about this, the thing that sets it apart from other delays, is that you can make really strong delay lines (i.e. high in level, relative to the dry signal) without it overwhelming the dry signal. Brilliant. However, as with any heavy-handed compression, do be aware that it can create a pretty audible "pumping." And even a sort of "clicking," especially material with prominent transients. So it's definitely not appropriate for any material where you don't want that. But when you're okay with that, this thing rocks. I think the best use of this is on material that is syncopated (i.e. not just straight eights or quarters), and when you use a note value that it something other than what you can set in most tempo-synced delays (the common stuff - 1/4, 3/16, 3/8 etc). Go for odd stuff like 5/16, 5/32, 15/64 – crazy stuff like that. This thing will start making reeeeaaallly unique rhythms. Put two or more together, serially, or in stereo tandem. And things can get really wild. Creative opportunities abound.
Some people won't use this because the delay is not tempo-synced: big mistake. Read my review of GDelay. Everything I said there applies to this one even more. Learn to use Excel and do basic mathematical functions. Your music will thank you.
And as with all GVST's stuff, it's very CPU-friendly. Barely even registers on my CPU meter.
Suggestion for improvement: it would be nice if you could opt to duck the dry signal in favor of the wet signal. That could be very cool.
