Matryomin is the unique, original erectronic musical instrument invented by Masami Takeuchi in 1999. It is a type of theremin – oldest electro-musical instrument invented in Russia – shaped Russian traditional wooden doll, Matrioshka. It hold form of Matrioshka perfectly, moreover, performing five octaves range. The distance of 1 octave at Low-Middle range is equal to Etherwavetheremin of Moog Music Inc. If you have acquired the basic technique to play theremin by Etherwavetheremin, you can enjoy playing Matryomin by same way. Matryomin is only pitch controlled theremin.
as Mike Dixon recently reported, the matryomin is popular with the robot crowd –
Here’s a machine that plays the Matryomin (Matryoshka doll + Theremin, made by Mandarin Electron). Instead of a hand controlling the Theremin, it uses a metal plate attached to a servo to control the pitch. The sound that the Matryomin produces is sampled into a Mac, this sound is converted to MIDI (using Miller Puckette’s “fiddle~” audio-to-MIDI external) and then compared with the target MIDI file in Max/MSP to determine the servo’s movement.
