Fertile Audio Tools Philosophy.

“Fertile Audio Tools” is intended to be a suite of “simple – not too
simple” audio plug-ins that focus on specific effects or sounds
Our efforts in designing these plug-is have been to provide interfaces
that inspire you to get your hands on the knobs. To encourage your own
sound design and creativity, and also to take advantage of the
environment of modern DAWs, such as automation, modulation
and so on. Or use a physical MIDI controller.
That’s why in NUSofting FATs the internal modulators and the preset
library are limited. You have to bend them by hand to get the most out
of them.

You will also find some unusual combinations in the Fertile Audio Tools.
There is more for you to discover.

The idea of “Sosir” was to create a bowed sound (by freezing the input)
from a plucked sound (roughly speaking: guitar pluck to bowed strings).

As you can see in the screenshot, you have basically two stages:
1) digital virtual bow
2) delay line with feedback and modulation by LFO
(There is also a small reverb at the end, but that’s optional).

You should use the “Sound Choice” selector to change the base timbre
and duration of the bowed sound.
Then you have the other controls to adjust it to your needs:
“bow” dry/wet, sub octave doubling, filters LowPass HiPass.

When the delay Time is set to about the same or less of the “arcata”
duration, the repeats (by delay feedback) would merge in a long
sustained sound, this make it sound more like the infinite reverb you

Note. That there are two different “Wet” controls:
the mix of “bow” effect and the mix of delay effect.
