If you hit the “X,” “C,” “V,” and “B” keys on your keyboard, you should hear the sounds you’d want to place inside of your Piano Roll in order to compose your melody. It resembles an electric guitar and sound quite like one. Left-click on “ADD” and left-click “FL Slayer” in the drop down menu. Once you open FL Studio 12, it should look like this. This “messing around” will include extending duration of notes, adding your track to the mixing board, and adding a “fruity parametric eq” effect to your track. Now for my final tutorial for FL Studio 12, I will teach you how to “mess around” with composing an instrument’s voice with a Piano Roll.
