Here is the ultra-powerful Yamaha MODX7, a keyboard synthesizer that combines the powers of a rompler with FM synthesis. This beastie has some truly excellent sounds and effects. A recent OS update endows the MODX with a sequencer, Moog-style filter, and wavefolding synthesis options. I've only used this MODX7 4 or 5 times; it just didn't suit my workflow, unfortunately. I do love the sounds, though. It is in mint (like-new) condition, and has never left my smoke-free, pet-free, child-free apartment. Comes with original box, packaging, power supply, and documents.
