I honestly do not see the problem... many of the patents have run out, and A LOT of other companies try to replicate older synths (funny enough, no one seems to wrinkle their noses at them!? why!?") ...
Second, many of these synths have been moaned about to the original producing companies FOR YEARS ON END... and none of the companies gave a shit about the people who wanted them... Behringer is giving the users what they want... if that is a problem for Roland, Sequential, Korg, Oberheim whatever, then they COULD HAVE LISTENED!
I give nothing for said original companies arrogance in this regard... they've had the opportunities to listen... but did not... that Behringer may be cloning curcuits to make them is something A LOT of other companies have done, if not whole, then partially... how many replicas are out there of the MOOG ladder filter, not from Behringer?
No... the companies a crying because Behringer sell their stuff so cheap they have to compete... this is the so called "free market mechanism" that all the neo-liberalists are constantly whining about as "GOD!" ... except when it means they they themselves are the hunted, and not the hunter...
So no... I have no qualms with Behringer in any way... and I may buy their DeepMind someday actually...
