The A-117 is a module that combines two functions - the top function is a digital noise generator with voltage controlled rate knob.  The bottom section outputs a mix of two square wave oscillators tuned like the 808 cowbell, and a spread of 6 square waves tuned to the 808 cymbal.  Overall an excellent sound source for generating simple percussion sounds.
