At this point, I would give serious consideration to the forthcoming Korg ARP 2600 Mini. I dislike the shrunken size, but ARP synthesizers now have me so infatuated that I think I might forgo the Rev2 for a 2600, presuming the latter's build quality is respectable. This is a huge shift for me, having been a total DSI/Sequential guy all these years. But I've decided that ARP completely owns my mono synth department, and that I really like the idea of having a dedicated monophonic instrument. In other words, I'm thrilled with my long sought-after pair of ARP Odesseys, so that my mind is now headed in a new direction. This is the result of having to wait three years now for the Rev2 to reach full maturity. All that while, I've been staring at my Prophet '08 Keyboard/Module pair and thinking how satisfied I am and always have been with it.
Along came the Odyssey with no window, no memory, no onboard effects, no sequencer or arpeggiator, and no operating system updates to await, one after the other. Goodness gracious, the simplicity is spectacular.
I do hope and expect that the Rev2 gets its final OS update this summer. But now I'm also a. enthusiastic ARP guy. I'm a two-timer.
