Luckily for you, I have three techniques that are sure to make you and your computer happy in that regard! Saving RAM…. When you get one of those libraries you will want to know a few key procedures about how to make things run smoother, quicker and take up less resources, like RAM and CPU. The sheer number of high quality sample libraries is astounding. Native Instruments' Kontakt Player should be a staple of any serious producer’s toolbox, if it somehow isn’t already.
