Impulse 25 from Novation is a USB MIDI keyboard controller featuring 25 semi-weighted keys with assignable aftertouch. It was designed to feel like an instrument rather than a computer peripheral and responds more accurately, and in a musical manner, when triggering a synthesizer or software instrument.

In addition to the keys, the controller features eight rotary controls and eight backlit drum pads, along with the obligatory pitch and modulation wheels. The controls allow for hands on manipulation of DAW functions, virtual instruments, and plug-ins. The included Automap control software takes the hassle out of assigning the controllers with its instant mapping feature.

The Automap software edit page looks just like the Impulse control surface. This labels what each knob, fader, and button is controlling. Once an automapping is finished, the window can be hidden. Control is available over the mixer, transport, and plug-ins of all major DAWs, as well as plug-in instruments and effects that don’t come with a DAW, like products from Native Instruments, Waves, or FXpansion.

The 8 drum pads are velocity-sensitive and respond to aftertouch. They are also backlit with 3-color LEDs to indicate the status of the associated clip. A built in arpeggiator takes advantage of the pads by enabling the performer to warp arpeggios. By switching the 8 pads in or out, the rhythm of the arpeggio can be changed in real-time. The shape, syncopation, and gate time of the arpeggio can also be changed.
