The Novation Impulse 49 is a professional USB/MIDI controller, also available in 25 & 61 keys. They each have a precision keyboard and a full control surface powered by Novation's Automap control software - Automap 4 - which makes getting hands-on with your DAW/plug-ins fast and simple. Impulse also has 8 back-lit drum pads which can warp arpeggios, roll beats and launch Live clips.
Impulse has a precision 'players' keyboard. It is semi-weighted with assignable aftertouch and has been designed to feel like an instrument rather than a computer peripheral. In addition to feeling good, it is incredibly accurate - this means it can translate musical expression (how you play the keyboard) extremely effectively. So your performance is reflected exactly by the synth or software instrument you are triggering.
Novation makes gear for you to play, create and perform music. They started out making high-end synths, and expanded into designing totally new music making tools. Novation products are designed by musician/producers who use the gear they design every day, and are always looking for fresh ideas. This is the reason bedroom producers and A-list artists alike use Novation hardware: because it has been designed by and for musicians. From the recording studio to the DJ booth, our equipment is freeing musicians to create and perform with their own workflow. Play. Create. Perform. Novation.
