As for the next Behringer synth. After the Minimmog seems to set, i'd vote for a 2600 remake as the one after it. Its mainly unobtainium and has a classic sound. When this is done or parallel to it, i'd like Behringer to have a look at a keyboard sampler instrument also utilizing wavetables and granular synthesis. This is a field where there still is alot to explore and hardly covered in hardware (anymore). 16 voices with analog filters would be very nice. Knowledge-wise i think multitimbrality is another field Behringers synth teams need to develope, as it is crucial for many tasks especially when it comes to samplers, romplers and so on.
