We also have Proxeeus. For what I know he is using only or mainly classic hardware synths and effects (or their modern clones)
Does his music sound oldschool to anyone? For me it does in terms of production but not so much in terms of composition and melodies (chaotic/agressive rather than hypnotic/entrancing) but I don't actually know much about 90's goa except for AP, MWNN some Blue Planet Corporation and such.
Btw, I think it's time for someone to invent "post-neogoa", blendng all these cool psytrance sounds, FM, metallic noises, alien insect sounds and such with goa melodies and "cosmic" atmospheres.
