Roland never released a Windows Vista driver for the XV series sound modules & I need to find the most compatible one to use.  It's a critical need because the sound module will be used at a church convention & I have to drive it with a church-owned laptop that, unfortunately, has Windows Vista Home Premium on it.
 
What driver should I use?  I have the sound module connected directly to the laptop using the unit's front panel USB port & I installed Roland's XV-50 series Editor that is supposed to eliminate the need for a MIDI interface.
 
Does anyone have an answer or experience with this?
 
Thanks,

Looking at the Web site it seems they never did write the driver. Your options are simple. 
 
Try the windows 7 driver. Vista and W7 are closer than Vista and XP. 
Upgrade the OS on the Laptop. Might be still offered at a reasonable price. 
Use another laptop.
