Magnetotron is an armonica mellotron mashup:re-blog from Hack A Day
[Michael] is a huge fan of old media formats. There’s something special about quarter-inch thick 78s, fragile blue cylinders holding music, and thin strips of mylar that preserve the human voice. He’s had an idea for a tape-based instrument for a while, and now that the Magnetotron is complete, we’re in awe of this glass harmonica and Mellotron mashup.
The Magnetotron is a large rotating cylinder that has dozens of strips of audio tape attached to it. The cylinder rotates with the help of a small motor. As the strips of tape rotate in front of him, [Michael] presses two tape heads up to the instrument, making some sort of sound.
Each strip of tape contains a recording of one note, like the venerable Mellotron. Instead of physical keys, the Magnetotron is played in a much more tactile fashion like the glass harmonica. The output of the Magnetotron is interesting with a whole bunch of wow and flutter. Check out the demo of [Michael] playing his instrument at NIME in Brooklyn after the break.
