Tube is an oscillator plugin for Korg’s multi engine. It couples a super-flexible noise generator with a feed-forward comb filter, a combination that we call “resonator modeling synthesis”. By modulating the noise density, the noise generator can create a very wide variety of signals such as bursts, gusts of air or sand, scratching, particles dropping onto a surface – and beyond. When these special signals are used to “excite” the resonator, Tube produces incredibly lively, nature-like tones: from woodwinds, plucked and bowed strings, to much more experimental, randomly evolving ones. Tube also features its own low-frequency oscillator, an envelope generator, and allows its noise signal to be used dry for even more sound design possibilities.


Korg Tube update 1.0.5
– Multiple performance and future-proofing enhancements.
– Improved resonator interpolation precision.
– Fixed compatibility with NTS-1.
– Updated and enhanced user manual.


  • Variable-density noise generator with 4 types: white noise, shot noise, velvet noise, semi-periodic noise.
  • Feed-forward comb filter with negative or positive feedback, plus additional low-pass damping filter inside the feedback loop.
  • Built-in lag filters for ultra-smooth parameter adjustment and modulation.
  • Built-in LFO with widely variable frequency (0.1 to 10 Hz).
