About the 8BD by acidlab
(Manufacturer's description:)

Modular version of the Bass-Drum of the TR-808.

The Gate In is `sensitive` and affects the sound. The higher the pulse (+5V to
+12V) at the Gate In the more attack and louder the sound gets. An additional control voltage or a Gate signal feed to the Vel. CV In (Velocity In)
will overwrite the dynamic control from the `sensitive` Gate In. Then the Gate In just triggers the sound (>5V) and Vel. CV In (0-12V) defines the velocity of the sound.
