Don’t fall into the “is this synth relevant” YouTube ‘influencer’ style way of thinking.
Synths are instruments and there are very very few (if any) actual synths that are no longer relevant.
The only exception to this rule is if you’re constantly making music that is following the exact current trend-of-the-moment, then you could ask is X synth relevant to X style of music and even then you’d be hard pressed to say that any synth would not be useful in some capacity to making any kind of music that features synthesizers.
With that out of the way, I can say with confidence the virus is 100% relevant to nearly (if not every) genre of music that features synths. I have an Access virus TI polar and I was (and am) blown away at how incredibly versatile it is. When I bought it, it was one of the last synths I bought after getting pretty much everything else that covered sounds that I was going for (and more) then I bought the TI on impulse because I love those Vengance demos so much even though I don’t like trance at all I loved the tone and texture of those demos and have for years so I figured I’d pick one up as like an extra synth…it quickly became one of my main synths once I started programming it I was very happily surprised to find that I could quickly get pretty much all of the sounds I could possibly want out of it. Not to say I went and threw out all the synths I already owned but if the TI was your only synth you’d be doing quite well. I’d even go as far as saying that it does analog emulation very very well, easily gets into Yamaha, Moog and Roland territory and that’s not even what I was looking for just a bonus.
So yes the virus is very relevant in all genres of music.
