The Sonic Forest includes a stunning UI that is meant to inspire your music. The serene imagery in the center of the interface gradually changes as you change evocative controls like “Flood”, “Shade”, and “Grow”, providing feedback for how the sound is being affected.

This center area is the heart of the granular ‘forest’ engine. As you play with the various articulations, pressing the Plant button captures the last played sample and stretches it across the keyboard. Then, as the Grow knob is increased, the granular forest effect is introduced. The Volume knob can be turned down completely to leave only the beautiful, evolving forest sound in its place.

The evolving granular sound is shaped and altered using the rest of the knobs in the center of the UI. For instance, Blossom adds grains that are pitched up to 2 octaves above the original sound. Flood washes out the forest with lush, purely wet convolution reverb. Tangle increases the speed and intensity of the granulation effect, and Wither puts a gradual envelope on the sound to fade it out over time.

The sound design possibilities with this forest engine are endless!

In addition to the granular engine, the Sonic Forest also includes an array of useful features like an arpeggiator and sequencer, microtuning, and 6-module FX rack (which can be used on both the source articulations AND the forest.)


Sonic Forest – Producer Spot

“Today I found something very special. A library that is extremely creative, well-designed, affordable, and even for good cause. I’m talking about “Sonic Forest” by Impact Soundworks. This library is based on a one it’s a kind instrument, sampled with a lot of depth and precision to create a unique sound, but beyond that Sonic Forest has a lot more to offer. (

Sonic Forest – SoundBytes Magazine

“Sonic Forest has unusual sounds that aren’t likely a part of most people’s existing sonic palettes…They are especially useful for soundtrack composers and very relevant to ambient, contemplative or even horror cues…The process of adjusting the sound usually delivers the fun that the product promises and you may find yourself hitting randomize ten or twelve times just to hear a few close variations of a basic sound just for the heck of it.”

Per Lichtman (SoundBytes Magazine)

Sonic Forest – Sounds and Gear

“I love when companies do this quirky experimental instruments, it breaks up to standard sounds and ideas we are used to and sparks your imagination in a new direction. I dig the interface a lot, it’s simple but useful, and actually powerful in terms of all that you can do do the sound. I say just go grab a copy, seriously, it’s 20 bucks and well worth more in my opinion.”

Sonic Forest – Sound On Sound

“Sonic Forest would be a good addition to any ethnic or world collection. Factor in the stunning granular engine, the giveaway price of $20 (25 percent of which is donated to charity) and I can’t think of one reason not to snap it up!.” (Sound On Sound)
