I'm going to state the obvious, why not take 1/2 of the Prophet X and make the Tempest 2.0 that a lot of us have been wanting? And get a great 8-voice synth in the process as well, that would be easier on the wallet than the Prophet X. It seems like the required Tempest 2.0 sound engine with sample import is all there. I would skip a desktop version of the Prophet X and go straight to the Tempest 2.0 that could function as 1/2 of a Prophet X, with 8 voices, that would still be a totally useful polysynth. I don't know, maybe I'm crazy?
