Drum
An electric drum kit is essentially a collection of sample pads set up in the same way as an acoustic drum kit. The pads themselves are designed to produce little acoustic sound, other than the dead sound of the wooden drum sticks hitting rubber. The drum kit sends electrical signals to an amplifier, speaker, or pair of headphones to be heard.  This makes them ideal for practicing quietly.  Recording electronic drums is very easy.  They may be connected using a USB cable or an audio interface.
