Siel Flow encapsulates the evocative nostalgia of an iconic 80s synthesizer, making it a must-have for genres like vaporwave, chillwave, nu-disco, funk, and those unforgettable Saturday morning cartoon themes.

Originally crafted in the 1980s by the esteemed Italian electronics firm Siel (Studio di Ingegneria Elettronica), this timeless 49-key analog synth boasted monophonic synthesis with dual oscillators and a charming built-in drum machine. Our meticulous sampling process faithfully captures its neon-drenched, retro-futuristic essence across 17 banks of sustains, 13 staccatos, and a handful of drum loops. To preserve every nuance of this vintage marvel, we recorded two microphone positions: up-close stereo and direct line-in.

After that, we created 20 atmospheric pads and drones from the source material to expand the library's versatility. Siel Flow also offers 12 wavetables, 20 stock synth waveforms, and an FX rack packed with amplifier emulation, reverb, delay, distortion, and more for boundless sonic exploration. Whether you want to craft immersive video game soundscapes, thunderous synth basslines, or unleash slick nasal brass solos, Siel Flow stands ready. From leads to pads and rhythmic presets, it's your ultimate sonic companion.



The Kontakt interface includes a suite of automation-ready sound-shaping controls to give you total creative flexibility. You have control over swell, attack, release, offset, vibrato, filter, pitch (coarse & fine), articulation switching, cross-fading and layering, and so much more.

This library comes with an adaptable LFO system, with selectable LFO shape, modulation target parameter, speed, intensity, tempo-syncing and fade-in time. You can also apply your choice of 12 lowpass, high-pass and FX filters, with assignable modulation targets such as velocity, modwheel, expression, after-touch, key position and step-sequencer table control. Our customizable arpeggiator offers a velocity table and control over arp direction, timing, swing, randomization and duration. We’ve included a key and scale lock system to constrain your notes to common scales and keys for easy melodic composition and live performance.

The interface is rounded-out by our modular FX rack panel, with 27 different DSP effect modules that you can assign in any of 8 available slots, in any order that you wish. You’ll find classic phaser, flanger, delay, distortion, amp and cab simulators, compressors, EQ, rotator and so much more. The Reverb effect includes our favorite convolution reverb impulse responses, including 99 different rooms, halls, chambers and outdoor environments, plus another 40 custom FX impulses to radically transform the sound and open up whole new worlds of musical possibility. We’ve added a great bank of FX rack chain factory presets to get you started!

Kontakt Format

This library is designed for the full retail version of Native Instruments Kontakt 6.2.2 or later. Kontakt is an industry-standard advanced virtual instrument software platform. You can view screenshots of this library's custom graphical user interface in the image gallery above. This library is packed with features to provide you a wide range of sound shaping parameter controls, each one totally automation-ready in your host environment or Kontakt's stand-alone mode. Learn more about Kontakt by Clicking Here.

This is a standard Kontakt open-format library, so the free Kontakt Player does not fully support it and can only run it in a limited "demo mode". However, the sample directories are unlocked so you can use them in other wav-compatible software, sampler and synth formats. The special Libraries tab doesn't support this open-format Kontakt library, but you can use the standard File browser tab and import this library into the Kontakt Quickload window for easy loading and navigation.
