Yes, they only mention the VS in the manual.
But they are speaking of the Prophet 5 in the "specs" part on the Arturia website:
Create your own synthesis patch by connecting independent modules. These modules are either innovative modules we introduced (such as Galaxy) or taken from the best synthesizers ever made (such as the Mg Modular, the Yamaha CS-80, the Roland Jupiter-8, the MiniMg, the ARP 2600, the Sequential Circuits Prophet 5 and Prophet VS).
Alternatively, use an existing synthesizer recreation: the MiniMg, the ARP 2600*, the Jupiter-8* or the Prophet 5*
Arturia, could you please shed some light on this?..
Thanks.
