Why Do You Need Pitch Envelope To Create Kicks?

Have watched many videos of people creating a kick from scratch.
All of them were employing pitch automation, but no one actually explained the concept.
So I was wondering, why is it necessary. Can't you make one by simply adjusting the amp envelope as you'd do with a regular bassline for example? |

Take a sine wave and apply a pitch envelope to it. Any synth will do.
Play with the decay on the pitch envelope and it'll become clear that's why you use it. The amp evelope is just altering the length of the note. |

| what you are basically doing when you are synthesizing a kick is emulating the way a piece of taut animal skin moves when struck by a soft beater. the amplitude of your sine corresponds to the strength of your beater (and consequently the amount of bulging in/out the membrane does). the speed of the membrane's oscillation corresponds to the pitch of the sine. when you hit the skin, the tension of the drumhead increases and then decreases as the energy from the hit dissipates. higher tension means faster vibration, means higher pitch. so the pitch goes down over time. |

I think you're really trying to say something else :conf: |

| well i wasn't talking about the off-beat if thats what you mean!! :) |

a kick needs attack, and general low frequency body. You don't have to use a sine wave but by using a pitch envelope , you create both the attack and the resulting bottom as the pitch levels out near 60 Hz with just a sine wave. This is how early drum machines synthesized them.
Because it is a pure sine, it is a very clean and pure signal which you can process easily. |
