Hi seadragon and welcome to the world of the !more-than-2000-people-trying-to-sound-like-the-around-2000-cs80s-produced" !!!
I must say I can only admire Arturia for its courage trying to model the hardest synthesizer to model in the whole history!!! About the synth itself it has still great bettering curves and I'm pushing the guys to do so !
About the sound of the guitar, aka GUITAR1 preset, keep in mind that the sound took GREAT advantage from the Touch response function which was unique of the CS80 and was never more replicated on any synthesizer after it : it's like 2 different velocity curves applied on the initial transient and the sustained part ( too techie? Let me know!) so that's why the plucked string sounds so "plucked" ! And so goes with the BASS preset, and mostly the FUNKY preset ( lots of them on Spiral and Beaubourg ,of course).
Unfortunately Arturia still didn't succed in re-creating this feel, which is part of the CS80's signature sound , hope they will do it.
Myself I tried to recreate GUITAR1 and the guys eventually implemented it on the version 1.5 (upper row, yellow button next to green button), anyway it resembles more to a CS60's GUITAR preset filled with velocity rather than the GUITAR1 itself....it's just a matter of velocity response :wink:
PS: Bouloutaur, BTW, as you know Vangelis' first synth was a Korg Mini 700s which is one of the crappiest sounding synths ever!!!
