The dTuner is a delay based effect that detunes the input-signal by modulating delays with sine LFOs.
It uses up to 7 delay nodes and each delay has its own sine LFO.
(In this documentation I will refer to the delay + sine LFO pairs as voices)

You can spread the phases of the sine LFOs which results in a supersaw like detuning of the input signal.
You can also add up to 2 seconds of delay to achieve a nice delay effect that detunes and defuses the signal with each repeat.

I uploaded multiple versions of the dTuner you can download.

  • A version with one input (mono in).
  • A version with two inputs (stereo in) that has twice as many delay nodes built in and therefore requires more CPU.
  • Early prototypes that have less functionality and also require less CPU.

Very nice work! Also thanks for the option of mono or stereo input.
