Creator of the Roland TR-909 Hi-hat
The designer of the instrument is Tadao Kikumoto, who previously also developed the design of the TB-303 model.
The device itself uses some digital and partly analog technology to generate sound. Equipped with a step sequencer, it allows you to program rhythmic sequences in one of several ways.
The drum kit made available by the TR-909, due to the fact that it is partially synthesized, can be modified within a certain range, specified for a given voice. This machine is one of the first in the world to be equipped with a MIDI interface.
