The Mopho x4 is currently DSI's smallest keyboard synthesizer. It's an understandably popular instrument, since it offers an inexpensive opportunity to have the classic Prophet '08 sound in a handy diminutive form. In light of the P'08's recent resuscitation in the form of the Prophet Rev2, it seems reasonable to hope for a Mopho x4 Rev2. I would think it would be a relatively simple technical matter to give it the same treatment, since this has already been done. And with the new technology DSI now uses, who knows for what reasonable price the Mx4 Rev2 might be sold?
