Altura Theremin MIDI Controller

Recommended Posts

The Altura is a MIDI controller that emulates the Theremin, the classic early electronic musical instrument. As you move your hands  in the air, the Altura transmits MIDI data to your synthesizer to control pitch, volume, velocity, bend, modulation, portamento, and more! Use it to control any MIDI synthesizer, such as the Macchiato Mini Synth. Ready-to-play or build it yourself from a fun and easy DIY kit! Get a sleek black acrylic cabinet — kit or ready-to-use — or  make your own cardstock  cabinet using the provided template.

The Altura Theremin MIDI Controller emulates the behavior of the early electronic instrument invented by Russian physicist Léon Theremin in 1920.  With Theremin’s gadget, as the player moves his right hand closer to one antenna, the device emits an eerie tone that rises in pitch. As the player moves his left hand farther away from the other antenna, the tone becomes louder. The device is very sensitive, and makes wonderful, spooky music – but it is very tricky to play. The performer can only play by ear: there are no frets in mid-air!

Our MIDI Controller version uses sonar range finders in place of antennae, and rather than producing sound directly, the Altura emits MIDI messages that are interpreted by a separate synthesizer. The Altura was designed as a companion to the Macchiato Mini Synth by Zeppelin Design Labs: there are a few special features that will only work well when paired with the Macchiato. Otherwise, the Altura conforms with General MIDI specifications and should easily control any device bearing this mark. Many MIDI devices do not conform to the General MIDI specification. In these cases, you may need to fiddle with your synthesizer some before it will respond properly to the Altura. Please download the Quick Start Guide and Reference Manual for all the details!
