Similar, yes. But it's the combination of display plus the 'soft knobs' and 'soft keys' that makes editing quite intuitiv and easy on the Prophet 12 (keyboard + module) and the Pro 2 in case you need to use the display. Also, the according OLED display gives you less of a headache than this rather cheap looking one Behringer's using, which rather reminds me of some clumsy 1990s ROMpler display (by today's standards) - not very nice to stare at for a longer while.
[Edit: Sorry David, I accidently hit the modify button instead of reply. Fixed it, but hence the note beneath your post.]
No worries - I'd agree on the display: the Korg Minilogue does so much more with so little.
In fact, the Minilogue vs. DeepMind provides a perfect inflection point in that the VCO-based Minilogue sounds great with a minimal, modeled delay; the DeepMind, on the other hand, makes use of multi-voice unison and quad effects to flesh out its sound, while the basic, single-oscillator waveforms sound as sterile as you'd expect them to on a DCO-based unit.
I'd love to see what Behringer thinks it could bring to market in the $500 street-price range–could they actually do it? Kitchen sink vs. teacup?
Plus: I don't really get what was/is so desirable about the Juno-106, on which the DM12's synth engine is based, in the first place. It's a pretty average novice synth at best.
The Roland Juno-106 is a slightly different beast with the KiwiTechnics upgrades installed; excluding the MKS-7 Super Quartet, there was never a proper rackmounted version, so the user experience is largely colored by the crap SysEx implementation, its pedestrian signal flow layout, and the noisy (yet characterful) stereo chorus effect.
That said–I much prefer the JX-3P, which gets you closer to Jupiter sound for such crazy little money (around $300 used, if you look hard enough) these days. Add the Kiwi upgrade and an external knobby controller (the Behringer one is quite good), and you're really pretty well set for a DCO-based, six-voice analogue polysynth. (And 61 keys!)
At six voices, you'd have to spend money to get to a Prophet '08 from that point, or to reach to a Prophet-6 or OB-6 to ascend to the next level.
