I am building a Eurorak. It is coming along nicely. Then that EvilDragon or whatever his moniker is, convinced me to buy the Behringer Neutron. Build quality is as good as any synth of its size but the sound, that little beast rips just about every synth I've heard to SHREADS!!!! I would seriously put it up against many other synths costing 10x's as much. It's a beast.
Neutron is an original and not a clone. I hear the clones are good but I have yet to be fully convinced. I've heard so many demos and there is something that's just slightly off about 'em. But, in truth if it was not billed as a "clone" the Model D on its own pulls its weight and so does the Pro-1. They both are killer synths but then they get compared to their clones and they're close but once a real mini moog lets lose I've never heard much that can beat it for its kind of synth. The Pro-1 on the other hand I think might even be a bit better than that original except they never quite get the filters full right. This is just me judging videos though. But, the real vintage synths just have a lot going for them. So if the real things are like 100 then I give the behringer clones like a 90. Is that extra 10 important? Depends. I know that the mini moog that extra 10 in the bass and in the expressiveness is audible. The only clone that beats it imo is the Midimini, also the ATC and SE 1 by Studio Electronic, but the one that is still in production cost $3000 and the rest you have to pick up on the used market and the prices are climbing even though they are still sub $1000.
All that to say for clones you can't beat $300 moog or $300 Pro1 for bang for the buck.
Behringer is killing it right now. In spite of what people think about the behavior of the company. They act like asses so it will definitely limit my purchases. But, there's a few more I want to get like the Cat, and the MonoPoly is looking promising.
I think next for them is going to be taking these designs and improving the features.
One more thing though is that they've kind of set the bar so now there are a lot of really good lower price synths. Moog just released a new one and that's got me more interested in what Moog is going to do. Roland will have to go back to analog and start expanding on that besides just their modular. Korg is trying. I think they may succeed soon. They did well enough with their reissue of the MS20 a while back. I think they may do more at a better price. These companies will bend to the will of the market place. So many Boogs and Pro1s were sold. Literally thousands of youtube videos of people jamming with these things and other Behringer synths where you can really only find dealer videos on many other synth released in the last 3 years. And, many others will follow in Behringer's footsteps so that there will be more to chose from if you decide that a company's behavior is important to you.
