When using styles meant for keyboards, other than my 770, I often find the voices blanked out , a lot of the time they are silent, but on occasions they will sound, when I try to identify the said voice, It just shows me the first instrument in a particular bank, E.g if it is a piano sound, then the grand piano will show, even though it is obviously not that. What I do then is simply save the mystery voice to the user section, these voices do not seem to be in the preset section of the 770. My question is , is it possible that a keyboard can reproduce a voice even though it was from a higher specification model. ps. I make sure there is no D.S.P. editing involved as .of course, this would alter the sound.
