I have a Variax 600 that I need to now use because JTV had to be sent back for repairs.  I am running the latest version of Workbench and Variax 600 firmware on a MacBook Pro.  I am powering the V600 with a Line6 XPS-AB box and using the Workbench Interface to communicate between the V600 and Workbench software.  When I try to write a custom preset to the V600, I get a dialog box labeled MIDI Timed Out with the message, " Your Variax 300/600 has stopped responding.  Please try resetting the power and click 'Refresh' in the tone locker.".  I follow the instructions and I am given an overwrite confirmation dialog box.  I click yes to continue.  I am then given the No Device dialog box which states, "Could not connect to Variax 300/600.  Please check all MIDI and power connections and click 'Refresh' in the tone locker.".  With the option to Configure or Continue.  If I click Continue there is no device connected.  If click configure no device can be found.

I unplug the cable in the input of the XPS-AB box and the V600 is noticed.  I click OK and Workbench searches the presets, lists them like I just started Workbench.  If I try to write a custum preset to the V600, I end up with the same issue.  Keep in mind that the Workbench Interface and the XPS-AB box are always showing green lights for conection and power supply.  Any help would be greatly appreciated.  I have a show coming up on Jan 25 and it depends on Alt Tunings that I use on my JTV 69 which will not be repaired in time for the show.

Thanks in advance!
