I'm still searching for the SinclaireStyle Techno synth, I know they use Access VIRUS Synth
Which one do you mean? The typical lead one? They've used several
The lead from Cybertoy/Devilginizer songs.
Well I suck so bad at sound synthesis I don't think I can help you. I would try to sample an oldstyle orch hit from a rave song and then try to make it more SS-alike with processing. It sounds pretty good on a hyper techno track, but maybe not that exact Sinclaire sound you're looking for.
Serum's probably his best bet ～ just mess around with it until you find the hyper saw you're looking for & tweak it .. or talk to Bratt over FB messenger, he's usually really nice and helpful if he's not busy. ♩
