PEople may hate behnringer as much as they like, and the work ehics of the company might be questionable, but they do deilver when it comes to the new, ever expanding, synth range.
The Model D is a very nice, well built mono synth. It sounds great and comes very close to a classic original which this was inspired by.
The synth has all expected features, and handling feels good. The knobs are a bit msall, but this is something we see commonly nowadays with the small sized devices and modular equipment.
Aside from the expected features the addition of daisy poly chaining multiple Model D's makes it also tempting to build your own analog poly synth.
It works as a desktop or eurorack device, with a minor downside being the loose bolts used to fix it in its case, instead of a full bar. Once you have dismounted it from the case to put it in a rack, you will have a struggle to mount it back with all screws in the original case.
All in all, for the price tag it has, this is an irresistable offer, that offers you the real classic power in a compact and afforable format.
I don't see why you would not give it a try.
