Voices for 770.

[Normanfernandez]

How can I get some of the Voices from the PSR 970 to the 770. 
Please help me. Thank you.

Basically, you can't do this. The keyboards' sounds are permanently held in Wavetable ROM and the 970 simply has more voices, that's one reason why it costs more. If you were able to simply take voices from a larger model and transfer them to a smaller model, Yamaha would sell less larger models.
