One of the things I like about SynthEdit is that so many people are now able to create synthesizers, a fact that inherently encourages novelty and innovation. Sure, many SynthEdit synths sound alike and are monotonously similar in UI, but there are also a good number of SynthEdit synths that sound *great* and/or offer synthesis capabilities you'll not find anywhere else.
RGB by Krakli is one of those synths.
I have a lot of SynthEdit synths installed, and so it was quite by accident that I decided to try RBG for a lead line in an ambient piece I was working on. I tried several of the presets, which were all nice but not quite what I was looking for - but then stumbled across one preset that was almost perfect. With a little tweaking, I had an amazingly lush and evocative synth sound, totally different from anything I could get on a more analog-style synth. With more tweaking, I found that RGB was really a flexible, distinctive synth.
Some of Krakli's other products are just as weird as RGB (some weirder) and definitely show a ton of innovation. In the case of RGB, I think Krakli hit the nail on the head - producing a synth that is not only innovative, but great-sounding and incredibly useful. Props to the developer.
