Node four-operator FM synthesis


Node is a four-operator FM synthesis engine for KORG prologue, minilogue xd and NTS-1. It is based on a classic setup with four sine oscillators (operators), which are connected together via multiple different algorithms that let them apply frequency modulation onto one another. This plugin neatly packages a total of 24 such FM algorithms and allows to set operator frequency ratios within an extremely wide range, delivering nearly 90,000 possible combinations – and opening a whole universe of timbres, from timeless classic to edgy modern. Node’s engine runs 2x oversampled and employs a special filter to suppress unpleasant aliasing frequencies, enabling a much cleaner sound even in the higher octave range. Node also includes a very flexible built-in modulation generator that can be configured in a number of ways: exponential or linear envelopes, multi-waveform LFO, sample & hold, or random triangle. With this many features, Node is arguably the most user-configurable plugin available for KORG’s platform – yet it’s designed to be incredibly easy to use.





  • Genuine four-operator FM synthesis engine
  • Internally runs at 96 kHz sample rate with an anti-aliasing filter, delivering superior audio quality even in the higher octave key range
  • 24 total FM algorithms: 12 base configurations plus two variations each – with and without self-modulating feedback
