In a forum post, Behringer shared this photo of their PCB, noting:
We have just received the first PCB (Print Circuit Board) and if all goes well, we should have a working prototype ready by next week.
As you can see it is quite a dense layout as squeezing a complete Model D design into a Eurorack format is not an easy task.
Please keep in mind that we are still many months away from a shipment date. A typical design cycle requires around 1-2 board spins, all depending on the audio performance as well as the subsequent compliance testing which includes EMC and safety.
Since people have shown interest, we will happily share with you the design milestones of this synthesizer, so you get a better understanding how an electronic product is engineered.
Behringer recently announced their plans to make a $400 Minimoog Model D clone, below:
The synth is designed to be used as a standalone synth or as part of a Eurorack system, with limited patchability.
