Chuck Delp Size of wave ROM Wed Apr 10 04:15:36 2002 4.19.176.4 There is no DIRECT relationship, since the ultimate sound quality depends both on the sound engine AND the samples that drive it. However, it certainly is indicative of the sound quality potential of a keyboard. Ideally, to minimize pitch shifting, every instrument sound should be sampled at every pitch over the entire range of the instrument. Combine this with hundreds of different instruments and it takes a LOT of ROM to do it right. So from this standpoint, the more ROM, the more authentic the sounds.
