Fragment - live additive synthesis with Open Stage Control/OSC & videos

Fragment is an online collaborative additive / spectral and soon granular live-coding web. platform, the spectrum is created by a live GPU script, the generated visual is then converted to audio by an additive process (re-synthesis).

This is a video of an one hour additive synthesis live patches coding session which use some of the new features coming soon in an update, features such as OSC support (Open Stage Control is used in the video to controls partials & some parameters), videos import with loop/playback settings which influences partials and new MIDI key release feature among other things.

The video demonstrate live visuals compositing as well.

Open Stage Control is used to setup partials and control some partials parameter in real-time such as attack and decay etc.

There is a morphing between the two row of partials setup.

The videos used for the visuals (simple compositing) are :
