Its a classic convultion reverb with the ability to laod up any IR that's been put into wav format. it hosts with a low CPU hit in FL. It has dry and wet levels, as well as stereo width for each and some basic controls like a pre-delay, stretch and self-convolve (which I don't understand but it can sound cool).... you also get a blendable graphical EQ where you just draw in the envelope with unlimited bands and continuously variable curves so you can go to town if you want shaping an impulse. Also, the screen that loads the impulses is a fully featured editor based around image line's Edison and you can dicker with an IR endlessly to create strange timbres. I actually really like this guy for hosting plate IRs and also use it 100% wet to run guitar cabinet impulses when I record my heads on a load box. This is a very good IR player all in all and is much easier on my CPU in FL than Altiverb, though man do I love Altiverb.
