"Visional Legend" is a work of live computer music and live graphics with a SHO (Japanese 
Traditional Instruments, like Suona in China) performer.  This composition is inspired with
the poem "q@" written by Shimpei Kusano and the SHO sounds performed by Tamami
Tono.  The music part of this piece contains two types.  The SHO sound is directly amplified 
to PA and is real-time processed by Kyma signal processing workstation with live control via 
MIDI.  The SHO performer may control the "special breath sensor for SHO" produced by the 
composer, and the sensing information also modify the live SHO sound part.  The background 
sound part is pre-processed with Kyma and Indy, and fixed to CD.  All sound materials of 
this part are SHO sound performed by Tamami Tono and reading speech of the poem by Junya 
Sasaki (Baritone).   Both sounds are processed by different algorythm in Kyma.  These 
processed materials are processed in Indy by original DSP softwares produced by the composer,
and re-mixed in the Indy.  The graphical part of this piece is considered as the 
environmental images of the poem.  There are some sources of the graphical part, for example,
live slide show images of Japanese scenary, CG generated by Open-GL softwares, natural video
images and live graphics of the performer with CCD cameras.  These source images are live 
switched by MIDI-Video switcher, and the output signal is connected to a projector for big 
screen.  The SHO performer may switch the graphics with the special SHO sensor.  The 
algorithm of real-time composition and graphical control is realized as a MAX patch.  The 
SHO performance is described in this score, but the most important policy is the 
improvisation.  The performer may have a Stop Watch to detect the position of the piece with
this score, but playing points are not fixed exactly.  She/He may perform with the 
improvisation spirit of her/his own, and she/he must listen to the sound in the whole 
performance.
