Была где-то библиотека Pure E-bass, не помню формат под какой сэмплер, можно вывалить...
"4 CDs All playing techniques like ghost notes, tappings, hammer-ons, 8th notes, slides slow, slides fast, pop ghost notes, pop slides, pop 8th notes etc. are also playable separately with up to 8 velocity splits per note. All playing techniques can be combined to new basses at will! already prefabricated combinations for each playing style with 8 velocity splits per note more than 100 different sound samples per note!!! more than 150 FX per bass (harmonics, fret noises, slides, noises, scrapes etc)."
