The TR-808 is a classic drum machine that used analog synthesis to create its sounds. The sounds have a very thin and pure quality and aren't grungy like it's successor the TR-909. In fact, the 808 has become the signature beatbox used in most R&B and hip-hop as well as a lot of dance and techno music. Booming bass kicks, crispy snares and that annoying cowbell sound made famous during the 80's are all part of the 808 and its famous sound.

Its 16 drum sounds include the famous boomy low kick, snappy snares, low/mid/hi toms, low/mid/hi congas, rimshot, claves, hand clap, maracas, cowbell, cymbal, open hihat, closed hihat and accent. All of the sounds can be edited and/or tuned and have individual outputs. Unfortunately it is not MIDI equipped but it does use Roland's DIN Sync.
