It's a rock solid controller, much heavier and sturdy than your average M-Audio Axxiom controller, but the real magic is in the software bundle. All the classic analog synths, 3500 presets to start with.
I also have some other soft synths, like the Roland Groove synth (bundled with Sonar, crappy editor), the Kontact FM7, Emulator 3, EZ Drummer, and the Cakewalk/Sonar PSyn II which is really nice.
I'll use the Emulator for the piano's and more organic acoustic instruments, but I'm an analog synth buff, so I'll be all over this Arturia package.
In a way, it's kind of redeeming my error of ever selling my Roland Juno 106 back in the early 90's. Regretted it ever since.
