Behringer’s UB-Xa, a redesign of the Oberheim OX-Xa, was “almost ready”. Behringer has subsequently declared that the design is finished and that beta testing for the synth has ended, indicating that progress has been achieved.
The UB-Xa has been in development for three years and was designed to be a direct replica of the OB-Xa at first but changed in the process. As a result, it has evolved into “a monstrous synthesizer with several capabilities and sound choices,” according to Behringer.
Behringer shows us their new synthesizer in the video below, so you can get a sense of what to anticipate.
