The Mopho x4 can export programs in Prophet 08 format, and the Rev2 can import programs in Prophet 08 format - could be one program, or a whole bank. The only issue with that: exporting from Mopho to Prophet 08 loses the settings for the sub oscillators and feedback, if those are used in this program - the Rev2 has one sub oscillator, so if used, its value would have to be reentered in the Rev2 after the import. If a program uses feedback, no way to simulate that with the Rev2.
If you’re only interested in this single program, could look at the Mopho x4 program’s parameters in a software editor and manually enter those into the Rev2. I wrote and released a free Mopho editor panel for the Ctrlr app - that can open a SysEx file of Mopho x4 programs and display their parameters (without needing a hardware Mopho connected).
