NUSofting releases Sinnah - Freeware VA Synth Plug-in for Mac & Win VST & AU


NUSofting has released Sinnah, a new freeware VA synth plugin.

Sinnah is available in AU and VST plugin formats for Mac OS X and Windows, supporting 32-bit and 64-bit hosts.

Sinnah is a VA synth, but instead of the standard subtractive resonant filter it uses a resonant delay network.


  • Sinnah is a synth based on a single complex oscillator that includes five waveshapes with increasing spectral complexity, harmonics level for all waveshapes, noise level, and a delay matrix.
  • The delay matrix can have various configurations, from a "triple chorus" per voice to highly randomized resonators, or tuned relatively to the note played.
  • The delay matrix can also do multiple slapback echoes.
  • The feedback control of the matrix can go from zero to extremely saturated and it's modulated by its own envelope.
  • The output of each voice is stereo via the delay matrix, which features a stereo spread knob.
  • The main analogue modelled ADSR envelope is loopable: two, three or continuous repeats.
  • The envelope can modulate the waveshape selection and the harmonics level.
  • The synth also features a subtractive stereo filter to carve the spectrum of the sound, somehow like an equalizer, with three filters: high pass, low pass and band reject (notch). The band reject filter also features gain and bandwidth controls.
  • A useful simple reverb is included.
  • The oscillator is antialiased and can play eight voices or mono, and features octave and fine pitch controls.
  • The GUI is fully drawn by vectors and resizeable, featuring an oscilloscope and peak meters. And eight colour schemes are available to fit your mood and taste.
  • An extended ToolTip display provides information for each control at mouseover. So you don't need to read a lengthy manual to learn what a knob or a slider is for.
  • The preset system is cross-platform, the files use the YAML format so they are very easy to read and edit if needed. Moreover, the preset names can support the complete international character set.

Planned Features

For this first freeware edition the pitchbend range is fixed at two octaves, this will change and there are many already planned features for the next release.

NUSofting say: "I will upgrade Sinnah following the requests submitted by users. So it means that we start with a features list and you can vote for your favourites, and even suggest features not listed yet. The features with a rate of five or above will be implemented in the Sinnah freeware, when we'll reach what I think it can be a critical threshold, Sinnah will split in Sinnah freeware and Sinnha Pro. Sinnah freeware will keep the features up to the "critical threshold" and will stay free. All next new features would be implemented in Sinnah Pro which will be payware. To vote for a features you can simply write on our forum or send an e-mail."

This is the first NUSofting plugin to use their brand new framework for development, thus they are happy to receive any reports or suggestions for improvements.

Possible features planned so far for Sinnah Pro or Sinnah freeware can be viewed here.
