duet for saxophone and
interactive electroacoustic devices

Several sensors detect the performer's movements (arm or hand). A computer receives these informations and manages digital sound generation as well as music spatialization among the concert room.

In 'Brise d'aurore', the movements of the arm allow to play with sound patterns, to trig wind breases and imaginary bird songs apparition. This sensor (not shown here) reacts to the arm gesture energy.

'La harpe magique' is another virtual instrument. A home made data glove allows to sense the performer's fingers flexion and hand inclination. So the performer can play and spatialize electroacoustic music (on 8 loudspeakers) in real time on stage, in duet with the saxophon player.

Electroacoustic sounds are produced owing to a sampler.

The glove : a new instrument

Action ! software - especially realized on purpose - collects and manages several gesture informations, coming from the glove or from the 'Brise d'aurore' sensor.

Action ! is a MIDI multi-sequencer (several independant sequencers) : up to 128 MIDI sequences can be trigged independantly at any time, even with different tempi ; sequences can be looped, stopped at any time or run to the end. Several sequences can be chained together. The most important point is the extreme temporal freedom brought by this software.

Several small MIDI cells were prepared in studio before the concert. This concert instrument particularities allow to compose and perform quite complicated sound textures, with really few compromises. I do not have to write more simply in order to be able to perform on stage.

 

performing space live on stage

Gestures are made simple and relatively clear for the audience :
- flexing a finger trigs the sounds or controls sound level,
- inclination of the hand (left, right, front or back) controls sound spatialization : either sound position of an new sound, either its movements on 8 loudspeakers all around the audience.

Thanks to that new instrument, I can trig each sound element precisely when I wish, I can control levels, lights and shades, timbre, durations and rhythm, as well as space.

Like an orchestra conductor, I can drive up to 128 zealous performers that are at my beck and call.
