Sequential Modulated Complexities

This experimental composition uses sequences from the SynFactory 1.15 Interactive Modular Software Synthesizer to create musical lines and phrasings. Multiple sinewave generators were ring-modulated with three more sinewave oscillators and fed into a sixteen-step sequencer, then output to a short stereo delay.

The oscillators and step sequencer were adjusted in real-time to create the cascading arpeggios and enharmonic ring oscillations. Stereo sweeping phaser effects were applied particularly towards the conclusion of the composition. Ambient arpeggiated pads were added from a Korg R3 synthesizer to create the surreal rhythms that connect the ring oscillations from the SynFactory 1.15 software.

The composition in its final form was re-equalised and shortened using cross-fades to eliminate abrupt harmonic changes. The visuals are modular synthesizer animated graphics and blended with backgrounds created on the Supernova 12 analogue video synthesizer.

It looks like analog video synthesis is starting to see the surge in experimentation that the Internet has brought to audio synthesis.

This is a preview of a Sergio Martinez’s DIY FPGA-based video synthesizer. Martinez connected the FPGA to an old computer monitor, and then recorded the images with a cheap webcam. The coloured dots are the  phosphor sub-pixels of the monitor.

Anybody know of combination audio/video synths? It would be interesting to see how you could combine the two to have the audio synth modulating the video.
