-Use pulse channel 1 for creating bass drum sounds. The amplitude envelope should have a strong attack and fast decay - try setting it to \$C1. Wave should be 50-50 high/low, even though other waves can be used for making the instrument sound more distorted. The sweep value is maybe the most important part in creating a successful kick instrument. It should have a high initial frequency and decay. Try setting it to a value of \$E3, and playing the instrument at note C-6. For a more snappy sounding kick, try experimenting with the envelope and length parameters.

Set \textsc{tuning} to \textsc{fix} or \textsc{drm} to prevent transposes from changing the pitch.
 
-It is also possible to use the noise channel for creating bass drums. Feel free to experiment around.
