Many thanks Manji for your response,
Well, insert USB flash memory into USB port of your Yamaha Piano. press Style Keys one by one. Select indian style. once selectted. you will find copy button. to copy style files. Once copied than press USB key. Your USB flash memory will open. Than see the Paste key. Press it it will be pasted to USB flash memory. Repeat the process till u copy all the important indian styles. Also do the same process for voices. copy and paste. Once completed. Remove USB and attach the same to your PC AND UPLOAD to this forum. It will be a great service to this Forum. If you are aware with basic PC skill I am sure It should not b difficult to you. If you still find any problem, please revert back. Alternatively any computer expert will do that for you in few minutes. I would appreciate your service.
Thanks and regards
