2-XM Polyphonic Controller
Behringer 2-XM Polyphonic Controller
This is the latest project - a four voice controller for the Behringer 2-XM. The 2-XM is based on the Oberheim SEM which was the synth module that was in the famous FVS (Four Voice Synthesiser) from 1978. I was lucky enough have one of these (courtesy of the record company!) and used it for live and recording until the mid 80s when it died! I still have one of the modules but the rest is long gone. I had given up all hope of ever replacing it until Behringer announced 2-XM which is a faithful but smaller recreation of the modern SEM (2000s). Each 2-XM is actually 2 SEMS - can you see why it's called the 2-XM ;) so if you have 2 units and a controller you would have the equivalent of the mighty FVS.
