First of all lets just say i do recognize one of those samples from the library......
I know the library well because i use them sometimes.. there is nothing wrong with samples i make them for others to use all the time they are all in the library
If you honestly want my help i am willing to give yo a few pointers to specifically asked questions. but you need to be 100 % honest back :) the main bass line in this has been in the library for a long time and i have heard it numerous times over the months thi have been here in others music
here is your first tip from me
to get more of an original sound using samples .. dig deep for them in the library
then you can add effex and cut them up .. be on the look out for samples that have sections of them that sound really good but other sections taht do not
you can cut out that parts that dont sound well and use the parts that do .. i do this because i find that i am the only one that will use that sample :)
