One of the important questions are now answered. The Behringer Synth will be a Poly Synth with DCO (Digital controlled oscillators). The layout remembers me of a Roland Juno Synthesizer and what is now also know. It will be four octaves. Check out here the third video of the Behringer Synth.
Isn't it four octaves and very probably four voices?
I think I write it wrong 🙂 Thanks for your comment 🙂 It's four octaves, if you calculate it in the video
