WOW filter 2 is not much like WOW filter 1. Its great in its own way but if you liked 1's modulation and stuff then don't delete 1 because 2 doesn't do the same stuff. WOW 2 definitely has some great sounding filter models. It can be subtle or extreme without a bunch of aliasing or delay.... anyway, definitely a good one but don't ditch WOW filter 1 if you have it. this doesn't sueprcede the old version, tis really like a different effect in the same camp.
I really only use this on certain bass sounds, particular the FM ones. I really like it though. It produces very digital type sound effects. It's easy to use and program and the interface is very inspiring.
Sugar Bytes are without a doubt my favourite developer. Their approach is always fresh, innovative, and their plugins are always rock solid, and crazier than a box of frogs. I have most of their products, yet somehow overlooked Wow, because it looks kinda basic compared to the likes of cyclop, but it was on offer, and I downloaded the demo to put it through its paces, and discovered it's an absolute beast !!! I have plenty of filter plugins, but when hearing them besides WOW, they sound like they aren't really cutting into the sound, and apply subtle EQ sweeps compared to this. WOW digs deep into the frequencies and adds all kinds of harmonics and squelches that made my jaw drop. WOW is very aptly named. Insane, and so very glad I bought it.
My only gripe would be that I wish it could be resized, but as sugar bytes are releasing updates at the current time, with new resizing options, this would just make it perfect !!
In short, with 21 variations of Moog and Korg MS-20 filter, this is the best sounding filter plugin out there. Hands down.
I love the choice of presets and the interface is very intuitive. It doesn't focus on exact frequencies or numbers. You're definitely more dependent on actually listening (just the way I like it). Probably my only gripe is the slight attenuation of the higher frequencies when the plug is activated.
