Hello,
CS-80 V4, Jup-8 V4, Prophet 5 V and Prophet VS V are all completely rebuilds. They can't use older versions presets. The same settings would'nt sound the same in the new version anyway. So no conversion possible.
The VC preset converter you mention in a thread, was to convert V-Collection (VC) - 4 presets to V - Collection 5 presets years ago. A new browser system was introduced.
You can search the forums for informations. You are not the first to ask.
Also - Keep in mind that individual applications has seperate forums.
