Novation's Impulse is a range of professional USB/MIDI controllers. They each have a precision keyboard and a full control surface powered by a brand new version of 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 clips in Ableton live. Impulse, available with 25, 49 or 61 keys, gives you instant access to your DAW's mixer, transport, and plug-ins. Impulse also comes with a stack of free software and sounds including: 1) Ableton Live Lite - powerful loop based music-making software?, 2) Novation Bass Station - legendary analogue bass synth as a software plug-in?, 3) Loopmasters sample library - over 1GB of royalty-free samples, and 4) Mike The Drummer - 502MB of live drum loops and breaks.
