The Impulse controllers are cost-effective, yet seem generously specified — so where’s the catch?

Impulse is the name of the latest USB MIDI controller keyboard range from Novation. There are three models: the Impulse 25, 49 and 61 and, as you’ve already guessed, the numbers refer to how many keys each model has. Beyond that, their feature sets are broadly similar. All have velocity- and aftertouch‑sensitive semi-weighted keyboards and eight backlit pads. They’re programmable in the traditional sense; you can use the LCD display and associated controllers to set up key splits and layers, and assign MIDI controller messages to faders, encoders, buttons and pads. All the models offer eight endless rotary encoders and DAW transport controls, but the Impulse 49 and 61 also have a bank of nine buttons and faders (which are non‑motorised and not touch-sensitive).
Around at the back, on all models, a USB socket handles the MIDI connection to your computer and is also the only power source, but there are also MIDI In and Out sockets. The rear panel also features quarter-inch jack sockets for sustain and expression pedals, and a Kensington lock slot, which will be welcomed by the education market.
Hands On

The Impulse’s back panel features a USB port, inputs for sustain and expression pedals, and a pair of MIDI I/O sockets.

From a visual point of view, these controllers are rather fetching. The white, grey and red colour scheme is a bit 1980s teenagers’ bedroom, but the end-cheek fins are a contemporary-looking alternative to yet another Moog-wannabe wood imitation. The placement and spacing of controls is somehow really ‘chunky’, and exceptionally clear. The case appears to be 100 percent plastic, and when you pick up an Impulse it creaks and flexes a little. It feels like it’ll last, though. The top and bottom keys don’t protrude beyond the casework, and in use everything feels firm and well constructed.
