Ever since I got V7, I started working on a track based around DX7 V synth (I'm not a keyboardist and usually start my songs with the guitar, so this is a bit new to me). I've found these synths to be inspiring , sound fantastic, and they're very easy to tweak (even for a non-synth guy like me).
Anyway, the best thing to do is check them all out using this Arturia Software Center: https://www.arturia.com/v-collection/asc Just pick any synth you like and demo it (super easy to download and install using ASC). Your ears will be the final judge.
