Yeah, Resolume feels like a jump through space and time when compared to Arkaos! Actually, when I started getting into concert/spectacle organisation, I searched for appropriate software online and found Arkaos. I couldn't get it to do as I want and thought I was the one who wasn't working appropriately
but after trying Resolume, I found that I suddenly knew how to do it!
... and then, it dawned on me that this new program was maybe, maaaaybe just better than the first one!
