The TUMULTUS is a monophonic electronic instrument of entirely analog design. The synthesizer is inspired by the Trautonium, and is controlled by a velocity-sensitive ribbon.
The Tumultus features an oscillator, sub-oscillator, low-pass filter and harmonic module. There are 14 controls for sculpting the sound, allowing you to go from very simple sonorities to rich, tumultuous timbres.
Ribbon range 2.5 octaves
Dimensions: 360 x 170 x 70 mm
Made in France

TUMULTUS is a musical instrument in the tradition of the first electronic instruments of the early 20th century. The Tumultus is strongly inspired by the Trautonium, created almost 100 years ago. The Trautonium is less well known than the Ondes Martenot, which appeared at the same time, even though it is also a highly expressive instrument.
The Tumultus uses the principle of a continuous pressure-sensitive ribbon to produce lively, dynamic sounds, just like a more traditional instrument.
The ribbon can be played over 2 octaves and half. It is pressure-sensitive. The volume depends on the pressure you apply, and varies according to the sensitivity expressed. You can switch from soft to aggressive tones easily and seamlessly. The dynamic range is wide, as with a more traditional instrument (acoustic or electric).
This ribbon allows a very instinctive approach to playing. It lets you alternate glissandi and vibrato naturally. The sound obtained depends much more on the way you play than on the programming. There's no envelope; it's your playing that varies the volume.
The Tumultus can be used to produce sounds that are closer to acoustic instruments, because playing the Tumultus is similar to playing a classical instrument.
The electronic design is simple and to the point. The Tumultus is entirely analog. It features an oscillator, sub-oscillator, filter and harmonic module. The filter is modulated by an LFO and by velocity.
The Tumultus also features a CV output and an audio input. So you can easily “trautonium-ize” your euro-rack modular system.
The Tumultus is designed to be an easy-to-use instrument, with more emphasis on expressive than synthesizing possibilities.
The Tumultus is an artisanal instrument, made largely by hand. Fulgur Audio's workshop is located in Colombes, near Paris, France. It takes several days to build an instrument.
