For this tutorial we will use the LB302 Bass Synth.

All you have to do is to:
1. Drag the instrument into the song editor
2. Press the slide button
3. Turn the slide decay all the way down
4. Turn the distortion up about 1/8
5. Press the triangle wave button
6. (optional) Turn the cutoff freqvency up for a "twitch" sound at the end of the treble notes.
