The earliest synthesizers used a variety of thermionic-valve ([[vacuum tube]]) and electro-mechanical technologies. While some electric instruments were produced in bulk, such as [[Georges Jenny]]'s [[Ondioline]], the [[Hammond organ]], and the [[Trautonium]], many of these would not be considered synthesizers by the standards of later instruments. However, some of these synthesizers achieved a high level of sophistication, such as the [[Trautonium]] of [[Oskar Sala]], the [[Electronium]] of [[Raymond Scott]], and the [[ANS synthesizer]] of [[Evgeny Murzin]].<ref>{{Citation
