I finally got a chance to play around with R-Mix the other day. My current studio room is quite noisy as I'm close to the furnace and I'm forced to record pretty close to my computer which I built to be "ultra-quiet" but my condensers still pick up some fan noise. So I tossed on R-Mix and used the anti hiss feature and POW... pretty much eliminated all that noise without really effecting the good stuff. Also I was having a heck of a time EQing out the boominess of my acoustic guitar track so I decided to try out the isolation thingy and within seconds I was able to get rid of it along with the last little bits of the background noise. It literally took me a couple minutes to do this on my first try. I really really like it and can't wait to try it out on some of my live stuff.
One thing that I think would be cool was if there could be multiple circle/square hot zones so I could get at various elements of the track in one shot. However I'm just going to make multiple clones of whatever stereo tracks I'm working on and isolate the specific part I want to focus on.
So what are you guys doing with it? I'm surprised there haven't been more threads about this. Cheers.
