If im right and you are just trying to use samples i didnt see anything saying you couldnt (i have pro so i might be wrong) but all youhave to do is show presonus where the folder if of the wavs you want to use got to the browser tab to the right click files right click and click new root tab (or find the files tab inside the files tap no search to were the wav files are (i make a folder for all my wavs with sub folders of different companys ect )when you find the folder right click it again and set as root now you will have a tab for that folder instead of having to go through all that again if you add stuff to it while studio one is open once its in the folder right click the new tab you made and hit refesh and the new stuff will pop up for use
