We created Momentum because we’re always looking for new rhythmic elements to add to our own music — especially sounds that break away from the pack. To make sure we built a totally unique sound palette with immense variety, we called on a diverse array of talented recording artists and sound designers, who each offered their own distinct take on the challenge of organic, unexpected percussion.

What did they give us? Over 2,500 performances and hundreds of multisamples that put a new spin on percussive sounds: Mistreated bass drums and rare hand percussion, hammered guitars and slapped cellos, giant boxes and tiny blocks, found metal objects galore, and more. It’s a fantastic collection of percussion loops that works great for filling in specific frequency ranges, or creating an entire groove from scratch.

Although there’s an enormous amount of content, it’s also very easy to find exactly what you’re looking for! Every sound is tagged and categorized both by material (like glass, metal, or stone) and frequency range (low, med, high, full), and the UI is both simple and user-friendly. The unprocessed and natural sounds give this library a versatility that transcends genres. If you wish to give your loops a more cutting-edge character, Momentum’s sound design capabilities (effects like filters, glitching, and chopping) are up to the challenge.

Momentum opens up a world of possibilities for film, TV, & game composers who need detailed, uncommon, real world sounds to energize their tracks, or who wish to morph these sounds into entirely new ones using Momentum’s sound design tools. You’ll be covered for everything from action and tension tracks to more intimate genres like ambient, world music, and folk rock (with an impressive selection of hand percussion such as shakers).

Momentum – Making Music

“Part of the attraction of the package is the range and variety of the patterns. If you find one which is close but not exactly right for a project, you can tweak it innumerable ways to get what you want. The other attraction is the actual samples….Of course, given the wealth of manipulation features, you can apply serious processing to the loops, too, just as you wish….If you use rhythmic patterns in your music, and need something more than a repetitive synth or arpeggiated bass line, it’s difficult to see how your music would not benefit from a touch of Momentum.”

Ian Waugh (Making Music)

Momentum – Sample Library Review

“Impact Soundworks has done an excellent job here of capturing unique and inspiring organic loops and wrapping them in a very usable and intuitive interface. Composers for any media will definitely want to give it serious consideration and I can also see this being a good tool for artists working in cross-genre styles (think Alt J/Beck/Bon Ivor). Additionally, some of the more ethnic instruments would suit certain world music styles…Momentum can certainly give your tracks what the title of the collection alludes to and using it is simply a lot of fun.”
