Hi and welcome to Arturia forums.
It's quite new that Reason can use VSTs. But i assume it woek like any other DAW and host. If so, then and sequence in V-Collection that uses MIDI SYNC should sync to Reason/ the host. Just remember that not all sequenced presets in V-Collection is set to use MIDI SYNC.
Please explore Arturia forums for further informations, as this and other questions has been answered allready.
