Can I edit/connect my Variax 300 to workbench by plugging my Variax into the hd500 & the hd500 to my mac via usb? Or will I need the entire Variax usb interface device?

I recently picked up a Variax 300 & was wondering if I could edit/update workbench by plugging my guitar into my hd500 pedal via ethercon cable & then plugging the hd500 into my Mac via usb cable? 
 

Or will I need to buy the vdi interface to be able to access workbench?

--- First, you will need the interface, as HD series connects with HD devices JTV/Standard/Shuriken using

Flash v2.00 or higher. Older Variax won't be recognized by HD devices such as HD-500/500X.

 

--- According to the Line 6 Downloads page, old Workbench only goes as high as Mac 10.8 OS. So even with the

interface, chances are not good.
