@suntower: Thanks for chiming in. I was close to think that I’m the only one who has missed the point of SLP, which I also just bought out of curiosity.
Maybe some tutorials can enlighten many of us about what SLP is meant for. At the moment it just looks like an audio tool using a Photoshop workflow to me, which is a nothing more than a gimmick. Sound design… well, I can do much weirder and unheard stuff with ISSE already using a white noise as its input. The UI is more advanced in SLP, but far from RX or WL spectral stuff. For example, I had a job with lots noise restoration on a classical recording lately, and I tried to give my new toy (SLP) a chance. But I was unable to set the UI in a way that I could even find what was needed in time, where RX did it from almost the default setting.
