Unique string VSTi for composers

We are very proud to release our first Kontakt music instrument. After years of development, recording and improving the engine, Spiral Strings is finally complete.

Main Page

Spiral Strings is a two layer instrument – it is divided into LAYER A & LAYER B. Functions for both layers are identical.
You can choose all parameters separately and individually for each layer.

Movements & Modulation

We’ve integrated a powerful modulation matrix. There are three LFO’s and two Step Sequencers.
Including cross-modulation capabilities.
You can choose modulation destinations for parameters on the Main & Effects Page.


The standout feature of Spiral Strings is the True StereoReverb. We’ve sampled Hi-Q IRs of the instrument, as well as the most characterful hardware and rooms..
You can also choose between fine- tuned Filter, Distortion and Tape Saturation.

True stereo convolution

This was quite tricky to achieve and took some time to develop. However, the end result is truly worth it and gave the instrument a new dimension.
We carefully selected only our finest IR’s of super characterful reverb hardware, rooms, and the instrument itself.

8 play styles – ranging from “normal” legato to more crazy ones like like Sul Ponticello or using a titanium stick, etc.

We recorded “workable” textures and phrases – all bound to their key-note and the musical scale in general

Three round robins of 10-15 second long files

Three microphone positions – recorded with low-noise sounddesign mics and vintage and modern Hi-End gear grails

Uncommon True Stereo Reverb engine with our own crazy IR’s
