Fragment - Abstract ambient JAM - Subtractive / Karplus / PM / Additive / Granular
Fragment is an online collaborative additive / spectral / granular / subtractive / PM synthesizer and live-coding web. platform, the spectrum is created by a live GPU script, the generated visual is then converted to audio by an additive/granular/spectral/subtractive/PM process, Fragment is basically a programmable noise-of-all-kinds software.
This is a video of a live jam session featuring all types of synthesis (in order : subtractive / physical modelling / additive-fm / granular) supported by Fragment and the improved subtractive synthesis algorithm (Poly BLEP) which allow fast and anti-aliased subtractive synthesis, this is still WIP (problems with filter resonance) but quite usable as demonstrated with several acid-like patterns.
Renoise DAW is used in the background to output audio + MIDI out and add reverb / delay (Fragment is also used for delay effects).
4 instances of the sound server are used on an Intel i7 7700, 14GB of RAM and a gtx 970 GPU.
