I saw this on the PK owner site.
http://www.yamahapkowner.com/index.php http://www.global.yamaha.com/download/usb_midi/index.html "The new operating system by Microsoft Windows Vista may have only been released today, but Yamaha have already stepped up to the challenge as they today release drivers for Windows Vista in both 32bit and 64bit versions.
Version 2.2.0 has been released for Windows 2000 and Windows XP. [USB-MIDI Driver for Windows(R) XP/2000].
Version 3.0.0 has been released for Windows Vista and XP, Vista for the 32bit/64bit versions of Windows Vista and the 64bit only version of Windows XP. [USB-MIDI Driver for Windows(R) Vista/XP(x64 Edition)]
Changes in Version 2.2.0 include:
- The model name is now shown as a MIDI Port name by default. If you want to use the
conventional Port name, open the Control Panel of the USB-MIDI Driver, remove the
checkmark of “Use Device Name As PortName,” and then restart the computer.
- The store system of the Patch setup has been revised, meaning that the Patch setup
made in the previous version cannot be used. Make the Patch setup again in this new
version.
- The problem in which the application didn’t respond or was forced to close when
logging on Windows with a limited (non-administrator) account has been corrected.
- Other miscellaneous minor problems have been corrected."
