The Synth

"Sinnah the sinner, is its sin to be free, or is its sin to sound so lush?"

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.

Moreover 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 crossplatform, 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.

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

Hard to describe its sound by words, despite the few controls the array of possible sounds is wide and wild

Planned features

For this freeware edition the pitchbend range is fixed at two octaves, see below the current list of the planned features.

I will try to 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 Sinnha 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 to nusofting@liqihsynth.com.

This is the first NUSofting plugin to use our brand new framework for development, thus we'll be very happy to read any report and suggestion of improvement.

You are invited to rate the features above or to suggest others not listed here.
You will be heard.

Known issues

This first release of Sinnah is a stable RC version, there are some small known issues that will be fixed in the next update, they are:

# : The ADSR envelope Repeat feature set at 2 or 3 sometimes doesn't work, "infinite repeats" always works
# : The lowest SampleRate is currently limited at 44100, so you may receive a warning message from your host during scanning.
# : The GUI of Sinnah in Ableton Live running on Mac OS X may sometimes not display correctly the first time you load an instance, to fix that you only need to close and reopen it.

Sinnah was tested so far on OS X 10.11.3, Windows XP and Windows 7.
Please report any other issue you may find.
