Rhythm Scope & Drums!

Drummer Gabriela Jimeno controls the Rhythm Scope! We set up her kit, two mics, a Rhythm Scope and a projector and recorded the AV magic! This video shows the Rhythm Scope's 16 modes responding to her drum beats. 

Production notes: The Rhythm Scope is receiving audio from two Shure SM 57 microphones (off camera): one mic is set up on the the kick drum and the other is above the drum set. The mics are fed into a mixer which sends the audio to the Rhythm Scope and an 8-track recorder. Unless the Rhythm Scope was set to random mode, we would set it to a specific mode depending on her beat.
