How to create those G-Funk style Synth lines.
First your going to need a Sine Wave or a Saw Wave with Set Loop Points or a really long sample of one. If you dont have one, I'll tell you how to make one in FL.
Go to Channels>Add One>3x Osc
Go to the channel settings of the 3x Osc
Now Turn the volume all the way down on Osc 2 & Osc 3
Now you have a basic Sine Wave.
Now that you have your sound, go to the channel settings of that sound and go to MISC. Now click the "Mono" Button, this gives the sound Mono Polyphony so it can slide from note to note.
Now open up the Big Piano roll and create a melody, but when your creating the melody make all your notes over lap. Now they will slide from note to note, this is usefull for creating those 90's g-funk synth lines.
