In the 9 really useful free VST instruments in 2013 series we will present a collection of essential free VST instrument plugins, the selection being mainly based on usability and performance.

Today, first three plugins: Uniwave V2 by Novaflash, Tyrell Nexus 6 by u-he and Charlatan by BlauKraut Engineering.


Uniwave is based on a substractive architecture with some FM capababilities, a few unusual controls permiting to tweak and bend your own sound.


  • Real Stereo sub / fm synthetizer
  • 8 voices polyphony
  • 1x VA custom VCO
  • 1x Sub. VCO (RING, FM, PD)
  • Unison mode, up to 7 stacked waves
  • VCF1 : 12 / 24 dB LPF
  • VCF2 : 12 / 24 dB HPF / LPF
  • 2x LFO
  • 3x Envelopes
  • Flexible modulation through a large dual matrix :
    • Poly and Mono signal splitted.
    • Stereo poly signals.
  • 2x Polypnonic Arpeggiator
  • Modulated delay FX


Uniwave V2


Tyrell Nexus 6 is a virtual analog software synthesizer programmed by Urs Heckmann (u-he) for readers. The sound engine is circuit-modeled and is similar to the u-he’s ACE.

  • 1 Ring modulator
  • 1 Signal feedback
  • 2 LFOs

Tyrell Nexus 6 V3


Charlatan is a polyphonic, subtractive virtual analog (VA) synthesizer plugin with a feature set just flexible enough to cover a wide range of sounds while deliberately abstaining from countless parameters and modulation options cluttering the user interface and distracting from the creative process.


  • 2 oscillators with triangle, sawtooth, rectangle
  • oscillator pulse-width modulation (PWM) and slew rate modulation (morphing between triangle and sawtooth)
  • oscillator hard synchronization and ring modulation
  • noise source with low/highpass filter
  • 2 ADSR envelope generators
  • LFO with host tempo synchronization
  • 3 filter types modeled after classic analog hardware: 4-pole (24 db/oct) and 2-pole (12 db/oct) lowpass, bandpass
  • filter code based on nonlinear zero-delay feedback technique for accurate emulation of analog counterparts
  • 3 voice modes: Monophonic with retriggering, Monophonic Legato and 8-voice Polyphonic
  • low CPU usage
  • 100% coded in C++
  • native 64-bit support
