and interactive systems
Most of these systems are exposed in details into my thesis (pdf, French). they were designed using Max/MSP and Jitter software.
The Scanned String is an instrument that uses a graphical tablet and a touch surface to control a Scanned Synthesis model. The Scanned Synthesis uses a virtual string which shape represents the waveform of the sound. A Max/MSP object (scansynth~) was developped to uses the Scanned Synthesis in Max/MSP.
The filtering string uses the same string than Scanned Synthesis to control a filter bank.
Evolutions of other instruments of LMA's Computer music team:
Musical drawing interface - quicktime video
The musical drawing interface enables to produce sound in real time with drawing gestures made on an interactive pen display. A second controller is used to change drawing properties (color, brush size, transparency, brightness,...)
Etheraction is a multiphonic electroacoustic piece using synthetic sounds produced with the Scanned Synthesis and the Filtering String. Two devices have been created to enable to perform live the piece. Those devices are based on the use of graphical interfaces and enable to control both sound synthesis and spatialisation.
