Inspired by the works of Jean-Claude Risset, I decided to build a machine to generate endless rising or falling sounds using a number of sine oscillators, band pass filters or ring modulators to process sounds through external input.

This plugin can be used as synth or effect. The number of polyphonic voices defines the number of risset tones.

Enjoy the eternal ride through spectrum and look forward to version 2 which is coming up soon, including MIDI control, LFOs, envelopes, ...

astonishgly good - especially with pads going through it. 9/10. would be even better if the LFO was midi clockable........ :-)

This is fantastic. I have to thank you not only for a great ensemble, but also for introducing me to Risset/Shepard Tones. I love auditory illusions.

This is much more interesting when a signal is feed to it rather then just using the sine wave. Really interesting I will look forward to the update.

To hear the BP filters working, you have to feed audio into it, of course. Use the player box and an audio file or run the plugin as vst fx in your host sequencer and send audio to it.
