@gulliver Yes you have absolute right so thats why i decided to change the way my instruments are organized because size is not helpfull and thats why i asked
for opinions and you gave the most accurate suggestions ! thanks

@kanadeva yes you have some right ! and thats what im going to do ! im going to create the appropriate categories so to help my creativity and reduce to the ones i need
with this method i can say ! hey this bass is not for me among the other basses , the same with the other instruments !
and yes this is not a really true problem ! i could have 2-3 good libraries and to remember their contents BUT i like to produce many genres
such us hip hop,orchestral,soundtracks,trance... so i need many good instruments and fx
