String Harmonics Meet Euclidean Beats

Blinksonic releases FR3TZ for NI Reaktor 6      25/09/18

Blinksonic has released FR3TZ for Native Instruments Reaktor 6. They describe it as String Harmonics meet Euclidean Beats... in a Granular Cloud. The company says that they had one simple idea in mind - to create a device which allows you to play guitar harmonics using MIDI and granular synthesis, but many more ideas came during the development. A spokesperson told us, “Not only is it a tool for sound designers/music producers, but also a player for those who love to have fun just by tweaking sounds.”

Here’s more details direct from Blinksonic…

String harmonics have a particular sound rendering and easily provide one of the most mysterious and subtle sonic mental images when they are punctually used in a guitarist performance. Obtained with a slight pressure on the strings with the tip of the finger raised above the frets, the harmonics deliver one of the most fascinating sounds that can be extracted from a guitar.
The tonal result of this technique gives a sound with a high pitch value, some really interesting natural distortion and artefacts, to be used as a substantial waveform source inside a granular sampler.

Basically, there are only 3 octaves of «  nodes  » available on a guitar, but here, FR3TZ lets you play this little «  squeals  » and «  squelch pickings  » in a granular synthesis process with MIDI. On the 4 sampled instruments, up to 5 octaves have been constructed, after a process of resampling and retuning all the original signals.

Due to the tonal differences and characteristics of each node, the result is a playable set of prepared strings based on multi sample instruments. Background noise, buzzes and unwanted frequencies are part of the original recording takes, and have been preserved on purpose in order to keep a similar acoustic feeling of a prepared piano. Then, various granular synthesis options and the complete effect chain allows to take advantage of this minimalistic waveforms to create organic pieces of reverse guitar, sweet string notes and even e-pianos tones.
