"Impact Soundworks software is an absolute mainstay in my work when it comes to Video Game and Anime-inspired tracks! The amount of ease and wonderful sounds these plugins offer allows me to get straight into writing and brainstorming."

"ISW creates some of the most inspiring & realistic guitar sample libraries. I had to write a bunch of really gritty, angry heavy metal & sports action rock cues. I used Shreddage 3 Serpent for leads and was blown away by its onboard processing, programming, and amazing live-sounding leads. I also created a signature sound based on the lead guitar in David Lynch's Twin Peaks series, originally played on baritone guitar. [Serpent] built a convincing replica of that sound just using on-board FX. It was so fun and easy to do!"

"Impact Soundworks' range of guitars and fretted instruments sound amazing and are crafted and nuanced with expert detail. Intuitively set up to get straight to composing. And I have a real soft spot for the juicy, screaming Shreddage 3 Hydra!"
The moment we heard Mattias Krantz’s new experiment — replacing every single hammer on an upright piano with real, metal hammers — we knew we’d found something truly unique that could inspire musicians around the world. It’s not quite like anything you’ve ever heard before. The sound is reminiscent of a particularly powerful and full-voiced harpsichord, with the dynamic responsiveness of a regular piano and the percussive nature of a hammered dulcimer.
While it’s a fun conceptual experiment, we think you’ll find that Hammer Klavier is also beautiful and a delight to play! Mattias worked with us to record his instrument in great depth; it has been carefully sampled to the fullest so that it’s every bit as playable and realistic as a standard piano. We created it with the same love and care that makes our Pearl Concert Grand a staple choice for many composers.
Think of this not as a sound design toolbox but as a custom upright piano with a unique voice. While Mattias might have destroyed a piano to get this great sound, we think you’ll agree it was worth it.
Mattias Krantz is a guitarist and YouTuber known for his wild, imaginative experiments with pianos and guitars. We are collaborating with him to bring his unique instruments to composers and musicians around the world. Hammer Klavier is the first instrument in this series, but it won’t be the last!
Console is a fully-featured mixer, modular effects rack, and pedal board, designed to give you full control over your mix. Effects include multiple EQs (digital and analog-style), compressors, spatial FX, modulation FX, amps, distortion pedals, reverbs, and more.
Each mic channel can be loaded with up to 8 FX in any order, plus another 8 slots on the master channel, with support for send routing as well. The new “Galois Reverb” added in Kontakt 6 Player sounds fantastic as an alternative to our included custom IRs.
Reviews
Hammer Klavier – Simeon Amburgey
“It is like the boldness and creativity of the sample developers, they’re just going all in and taking us into some very uncharted territory, and unheard territory […] see, it’s just very beautiful, but it can get really crazy too.”

Hammer Klavier – Synthsonic
“Although it has a unique sound, it seems to be familiar with various songs, so it seems to be highly versatile. The hardness of the real hammers fits in well with EDM-style music; however, because of the crisp acoustic sound, it can be used for any style effectively. It’s perfect for when you want a piano sound that’s a bit different. A gem that seems to reach out when you want a piano but want to choose something a little different.”
