i guess that's what I'm asking... is anyone using the XW as a controller in Win 10? i looked for a midi driver to reinstall for the XW but could not find one... anyone have a link for that??? i can use the XW Data Manager prog and work on patches fine. EDIT... I loaded the 64bit drivers from the CASIO site, even tho it didn't include the XW in the list, and it is functioning now. http://support.casio.com/en/support/download.php?cid=008&pid=72 I don't know if the OS upgrade wiped out the old driver or what. It may have been a brain fart from upgrading the system 3 years back from 32 to 64 bit and never loading the new drivers, since I normally don't use the XW with my desktop computer.
