* "Without doubt the most powerful and genuinely useful percussion app on the App Store right now" Computer Music * Reached the #1 paid music app in 5 countries * SonicTouch (www.sonicstate.com) gold award Impaktor is a drum synthesizer with a vast sonic palette, that turns any surface into a playable percussion instrument. You just slap your desk like you would a real drum. The real acoustical impulses from the built-in microphone are used as an excitation source for advanced sound modules that simulates behavior of membranes, cymbals, metallophones or strings. This makes Impaktor a highly responsive and expressive instrument. With semi-modular architecture and several types of synthesis, Impaktor can produce a wide range of tones, from acoustic, like Tabla, Djembe, Marimba, Cymbals, Metal bars to electronic or industrial sounds. We strongly recommend using the app with wired headphones to avoid acoustic feedback and ensure ultra-low latency. (USB-C to 3.5 mm Headphone Jack Adapter, USB-C headphones or an audio interface). You can use the Impaktor app with a contact microphone or analog drum pad to achieve isolated and sensitive input, reducing ambient noise and enhancing trigger accuracy. Enjoy the most realistic virtual drumming experience available for mobile devices!
