The TD3, along with the RD6, is a copy (or rather, a reconstruction) of the famous TB303 and TR606 by Roland, which have been used by renowned artists such as Prodigy, Fatboy Slim, Daft Punk, and Twin Apex. They are considered to be among the most important synthesizers that have contributed to the creation and evolution of electronic dance music. Both are analog machines, which means that they produce sound on their own and have distortion effects, potentiometers for sound mixing, and drum intensity. They can be connected to a computer via USB and function as MIDI controllers, allowing you to write MIDI and use any sound you want from VST programs. Additionally, Behringer provides a program called SynthTool, which allows you to create patterns, make modifications, and save them.
