I had been eyeing that Arturia V collection. The cost isn't too bad at all! I had a demo a few years ago and I really only messed with the grand piano and the DX-7. I'd love to do some nice warm pads on a Juno-106!
I picked it up on Splice starting around Christmas. Great low-cost way to try it, seems fairly catch-free. (The only real downside I could tell, was if you stop subscribing, and they no longer offer it, then you could lose out on your "investment" vs completing the purchase. Perhaps licensing across computers or running their software, but it doesn't seem worse/more invasive than any typical audio DRM.)
The Vocoder is so fun to play with! A lot of great sounds in there, I gotta spend some more time with it!
I can't speak to the accuracy, I only have a few bits of hardware, but V collection sounds really good on its own. As for the DX-7, Dexed is really popular.
If you have an iOS device, KQ Dixie is a pretty good DX7 emulation. It’s an audio unit, so you can load it into a host (“DAW”) and add an effects chain, even though it’s on a mobile device
I've owned a couple DX-7s. I just can't get into the original. The DX7 mk2 was a really cool instrument and I'm glad the V has some of those sounds. I messed with FM7 a bit too. I've seen mention of Dexed for years but haven't tried it out.
