Yes, I agree, unforunetly the MS20 desktop is unavailable, I would more than likely get the desktop version of the arp as well, although the faders leave a lot to be desired.
I want the sounds though and no getting around the cheap feel of these synths without buying originals which is am not able to do.
Soundwise though, I think i'm going to have to go for the MS20 for its more unique sounds then grab an arp next in a few more weeks/months, well, thats unless something else catches my eye lol!!!
I'm kind of gutted the MS20 desktop is unavailable and korg doesn't do runs of this unit pre-built its like they are missing a trick if you ask me....
