Just revisiting this topic I started a while ago; it still looks viable. But now I'm somewhat wondering if the Origin is discontinued, with the evidence being later and later shipping dates to replenish retailers stock stateside...
Man: I really hope not.
Antoine, Philippe, et all: I bought Mark M.'s 'replacement' Origin keyboard off of eBay; it has greatly exceeded my expectations. It is, and will remain, my all-time favorite keyboard instrument...it is a masterpiece.
I would hope that regardless of O's future, you do your darndest to support it, as it has no peer.
Even the Solaris is essentially repackaged and enhanced Creamware tech using presumably a mature SDK to write the necessary osc etc. code; Arturia bit off a much much bigger slice of DSP pie.
Hail, Arturia! And long live the Origin!
Masterpiece!
