Opinion from GearNews also on the MS-101 about current status of Behringer’s synth development, and ‘over-promising’:
With no sign of the RD-808 and the promised pre-Christmas release date, the RD-909 being bumped, the UB-Xa behind schedule, Pro One and Odyssey only in pre-production it seems that Behringer has underestimated what it takes to produce this kind of synth. They need to slow down, give more realistic release estimates and focus more on getting it right than over-promising to the synth community. But it will all work itself out and 2019 may well belong to Behringer and their reimagining of classic synthesizers and drum machines.
I would add a small coda to this: at least Behringer is slowing down, and picking up the loose ends, AND hiring more pros, rather than rushing stuff to market, and cutting steps and quality. AND by the way, the list of systems listed here being well down the pipeline is substantial.
