Finally, Yamaha software officially supports Windows Vista.
Please check the Download page and each program's System Requirement. All editions of Windows Vista (32 bit version only) is supported. (Some programs don't support Home Premium/Home Basic Edition, please see its System Requirement.)
I guess most of you use your PC for Studio Manager. Please check your USB MIDI driver. V3 is for Vista. Other programs, such as Studio Manager and PM5D Editor, don't need update. Their current version programs were tested with Windows Vista and confirmed their compatibility.
Thank you for waiting for this information.
