Patches and discussion for Ensoniq VFX family

Please excuse the newbie question, but does the sequencing software 
load with the OS when you load the OS from a disk, or is it on a 
separate disk? When I try to use the sequencer (by pressing any of 
the sequencer buttons) I get a message saying "I need to load the 
sequencer" or "no sequencer loaded" or whatever the standard message 
is. I haven't yet reloaded the OS, but I downloaded one (VFXSD 
v2.1/2.0 OS) from route66 and the site doesn't clarify whether the 
sequencer is included.
