Found this guy through Rddt ages and ages back. He put up a video of the Korg Poly800 side by side with his plugin emulation, and tbh it was spot-on for me.
You obviously need some way to load the software instrument (eg a VST shell or a DAW/music software like Cubase) and some way to play like a midi controller (you could program in notes in most DAWs though)
I feel like this guy needs more love for the sheer effort he’s put into creating these.
Not (officially) free, but you might like some of Cherry Audio’s plugins, if you haven’t tried them. They all sound pretty excellent.
I’ve played with the demos of the one of their moog and one roland I think. Very nice.
I have a hard time finding synth bass sounds I like, but I love their Lowdown bass synth pedal VST. I’ve started adding it to nearly every patch. u-he Diva is another with good Roland-y options, but that one’s pretty well-known already I suspect.
Ahh thats based on an old Moog Taurus i think it was called. The guy from Rush used one.
Dexed still does super low bass. All that FM thump, too.
Nice, thanks, that’s another new one to me. Will try these out tonight.
