New Music Controllers

CCRMA Summer Workshop 2015
June 29-July 3

Instructors: Sasha Leitman sleitman@ccrma.stanford.edu and Michael Gurevich mdgurev@umich.edu

COURSE HISTORY AND DESCRIPTION

This course was originated in 1996 to offer a hands-on approach to interaction design for musical applications. It was originally helmed by Max Mathews and Bill Verplank, and early on was jointly taught over teleconference with instructors at San Jose State and Princeton. In 2002, CCRMA began offering an intensive workshop version of this course during the summer. Other past instructors include Matt Wright, Edgar Berdahl, and Wendy Ju.

This workshop integrates programming, electronics, interaction design, audio, and interactive music. Focus will be on hands-on applications using sensors and microprocessors in conjunction with real-time DSP to make music. Specific technologies will include Satellite CCRMA, Beagle Board, Arduino Nano, Pd for music synthesis, and sensors including force-sensitive resistors, bend sensors, accelerometers, IR range finders, etc. Participants will design and build working prototypes using a kit that can be taken home at the end of the workshop. Further issues to be explored will include modes and mappings in computer music, exercises in invention, and applications of sensors and electronics to real-time music. The course will be augmented by a survey of existing controllers and pieces of interactive music.

Tuesday Afternoon

Solder your accelerometer and proximity

Sensors: Proximity Accelerometer

Max for Beginners Lecture

Max instrument: http://ccrma.stanford.edu/~gurevich/Max.zip

Goal: Create a musical interaction. using 1 continuous and 1 discrete sensor.   Think about how the physical gestures that you are using and the type of sensor (continuous or discrete) interact with the sounds you are controlling.

Homework: Come up with at least 5 ideas for your performance.  Sketch them out.  Include details such as materials, sounds, sensors, gestures. Think about how the physical gestures that you are using and the type of sensor (continuous or discrete) interact with the sounds you are controlling.

Wednesday Morning Present your ideas
