The last time there have been (and are) a lot of posts regarding GS3 & rewire problems. So I'll give a positive input in this case.
The link

http://www.v4m.net/music/gim/IsAnyBo...CrabNebula.mp3

points to the composition

"the.crab.nebula"
super.nova.4.daw.guitar.&.strings

which have had the first performance last year in Vienna with the Ensemble Neue Streicher, Gabriel Guillén, guitar and Jovan Pesec, daw (ZTAR).

The composition uses 2 VST synthesizers (M42 Nebula & Camel5000) and Gigastudio 3 in rewire mode in a forte ensemble rack.
The synthesizer part & GS3 was controlled using a MIDI guitar (ZTAR)
Below you can see my little son Oskar playing the ZTAR.

Each "string" of the ZTAR is conncected to synthesizers or GS3.
e --> M42 Nebula
h --> Camel5000 (Crab Pulsar)
g,D,A,E --> GS3 (lib.: Dream experience & Drone Archeology)


The whole composition is based on images of the crab nebula taken by Voyager and the impulse of the crab.pulsar (used in Cameleon5000).

And a 2 bar folks melody which Gabriel Guillén heard two years ago on a concert tour through Algeria.
The backgound of the compositions (which is part of my space.suite "is.any.body.out.there?) is a starship which enters the Crab Nebula and leave it again.

Have fun and give feedback,

Jovan
