Yasmin Electro-Mechanical Rhythm Sequencer
The Yasmin Electro-Machanical Rhythm Sequencer is a 1-10 step sequencer built into a defunct Otari MX55 reel-to-reel tape machine. The electronics are based on a very simple circuit that I first saw above the sales counter at Al Lasher's Electronics in Berkeley. A 555 timer controls the tempo. each pulse of the sequence can be sent to one of four original tape machine solenoids: motor brakes, tape lifter, and pinch roller. Contact Microphones in key positions amplify the sounds of the solenoids and mechanisms and are mixed through a 8 channel mixer built into the chassis. The output can be routed through external effects for additional processing.
YEMRS began as a machine intended to allow a friend to play intuitively with rhythms. As it developed working on the project also became a way for me to work quietly and stay out of my students' way without getting so involved in my own work that I was unavailable to answer their questions and assist when they needed help. Once it was finished I didn't fully realize how much fun YEMRS could be until I watched Daniel Yasmin, percussionist extraordinaire, have a ball with it.
