hypercyclic v1.9


LFO-driven, midi-mangling arpeggiator

available as VST, AU or standalone app
for windows, mac and linux
now with MacOS BigSur and Monterey support

what is hypercyclic?

  • an LFO-driven MIDI arpeggiator, gate effect and step sequencer
  • for mangling sustained MIDI input chords
  • the output of which can then drive other MIDI instruments
  • acts either as a VST or Audio Unit plugin for your DAW, or as a standalone application
  • the original hypercyclic won 2nd place in the KVRAudio.com Developer Challenge ‘07
  • the sweetspot for hypercyclic is the narrow border between chaos and regularity. Or, in other words, how to induce a certain pleasant randomness and syncopation, yet forcing everything to align again on the bar or beat boundaries

how do you use it?

  • the main use for hypercyclic is to generate midi that can be recorded and/or sent to other plugins. However it also features a simple built-in synth for testing purposes
  • you can use two tempo-synced LFOs to modulate various parameters for creating interesting rhythmic effects and chord variations
  • a unique feature is the possiblity to modulate the sequencer step size itself, which is useful for creating glitchy stuttering effects
  • another thing you can use is a groove function for playing slightly off the beat. The groove parameters can also be modulated over time by the LFOs, adding to the rhythmic variation

it’s free

  • hypercyclic is free (as in beer)
  • if you like it, and want to help, share it with your friends, and rate it at KVRAudio
