The OB-Mx was Oberheim’s attempt to make a ‘modern’ modular synth. It had a very protracted and painful development cycle. The original design team was replaced with veteran synth designer Don Buchla, who restarted the project pretty much from scratch and was able to bring it to market. Expensive and plagued with software and hardware bugs, this synth is a polarizing yet unique item that has found its way into many musician’s setups.
