4-Operator FM Synthesis Engine For Korgs

Sinevibes releases Node plugin for KORG prologue, minilogue xd, and NTS-1      27/11/20

Sinevibes has announced the release of Node – a four-operator FM synthesis engine for the KORG prologue, minilogue xd and NTS-1. They say that 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. They tell us that it 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.

A spokesperson told us, "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 a self-modulating feedback loop
  • Individual frequency ratio selection for operators 2, 3, and 4, plus variable operator detune
  • Flexible modulation generator with 24 modes: exponential envelopes, linear envelopes, multi-waveform LFO (triangle, saw, square, pulse, trapezoid, peak), sample & hold, and random triangle
  • Built-in lag filters for noise-free, ultra-smooth parameter adjustment and modulation

Pricing and Availability:
Node is immediately available for $39. Existing Sinevibes customers are eligible for special upgrade pricing.
