Refractor

Refractor free software-synthesizer by Noizefield Instruments

Refractor is a free software synthesizer for Reaktor, developed by Noizefield Instruments. Available format(s): for Windows, macOS.

REFRACTOR is a synthesizer for Native Instruments Reaktor, based on Karplus Strong synthesis. Instead of using noise as the impulse this synth does use sample-wavetables. Therefore the results are much more experimental, unforeseeable and multifarious. Several delay lines, a multimode filter and special tweaks make this synth unique.

Works with Native Instruments Reaktor 5.9.4 and above.

RedTron SE

Redtron_SE free rompler by Artifake_Labs

Redtron_SE is a free rompler VST plugin developed by Artifake_Labs. Compatible OS(s): Windows.

RedTron_SE is a Special Edition of the RedTron_400. This VST plug-in uses the Taijiguy’s Mellotron samples (taken from a 1973 Mellotron M400S – Serial #500). The samples have been cleaned (not too much) by removing an annoying 60Hz hum and some unwanted “clicks” and “pops” here and there.

Features :

  • Nine sound types: MKII Flute, MKII 3 Violins, M400 Cello, MKII Brass, M400 Combined Choir, M400 String Section, M400 Woodwinds, M300A Violins, M300B Violin.
  • No loops: as the original Mellotron, each sound is eight seconds long with, in many cases, “the bad endings”.
  • Exclusive “Mellotronic Click Switch” (MCS). On real Mellotrons, “Click” can be heard at the beginning of a note, when the tape comes in contact with the replay head. On REDTRON_SE, these “clicks ” are randomly generated when you hit a key : you don’t hear twice the same and they can appear on any note. A rotary knob allows you to control the effect intensity (of course, you can also completely disable it ). Note : this function is inactive when the attack parameter is set to any value different from zero.
  • Layer (two sounds A & B) and split possibilities (octave shift).
  • Independent parameters for sound A & B:
    • Volume, Tone, Pan, Tune, Reverb, Delay, Attack & Release, Octave & Note parameters.
    • Delay effect (Amount, Time, Feedback & Pan parameters).
    • Reverb effect (Mix, Width, Size & Damp parameters).
  • Global Volume control.
  • Global Tone control.
  • Global Pitch control.
