Meloncillo is graphical front end for the spatial arrangement and composition of sounds, providing a spatial scene view and a traditional timeline view which allows you to end and transform the trajectories of sounds. Supercollider 3 or any other open-sound-control server (for exampel Max/MSP) is used to synthesize the sound. An open plug-in interface concept allows you to exchange and re-programme the synthesis algorithms. examples include amplitude matrix panning, doppler shift, filtering, distortion, binaural convolution.
