Arturia KeyLab 61 mk3 Ultra: Flagship 61-Key Control in Bold Ultra Orange

The Arturia KeyLab 61 mk3 Ultra is a special-edition 61-key semi-weighted USB MIDI keyboard controller finished in a striking Ultra Orange colorway. It carries the complete premium mk3 specification — aftertouch keybed, 3.5-inch color screen, touch-sensitive faders and encoders, and twelve RGB pads — across a five-octave range, with only the bold finish setting it apart from the standard model. That orange chassis makes the controller the visual centerpiece of a studio or stage the moment the lights come up. For the player who wants flagship five-octave control and a look with real presence, this is the standout.

Five Octaves for Two-Handed Performance

The 61-key span gives both hands independent room, so you can hold a chord low, solo up high, or set a split without endless transposing. The Ultra delivers that range on a velocity-sensitive semi-weighted keybed retuned for a balanced hybrid feel across synth and piano playing. Channel aftertouch and release-velocity sensitivity let held notes swell and breathe with your fingertips instead of sitting flat. For arrangers and pianists, this is the size where the keyboard supports the full performance rather than limiting it.

The Redesigned Semi-Weighted Aftertouch Keybed

Under the Ultra Orange shell is the same mk3 keybed Arturia rebuilt with reworked balance, weighting, and spring tension for clean fast runs and even sustained chords. Channel aftertouch converts continued key pressure into vibrato, filter movement, and modulation with no extra hardware needed. Release-velocity sensitivity registers how quickly you lift each note, a nuance flat controllers cannot read. Newcomers get an action that rewards touch, and seasoned players get a gig-ready keybed that carries real dynamics into every instrument.

A 3.5-Inch Color Screen for Eyes-Up Workflow

The Ultra includes the line's 3.5-inch, 480x320 full-color display with eight contextual buttons that adapt to the on-screen menu. You browse sounds, edit parameters, and read clear feedback on the hardware, keeping your attention on the keys instead of the laptop. The context buttons make loading presets and moving through Arturia's libraries a quick glance and press. On the bold orange panel, that bright screen is both practical and part of the visual statement.

Touch-Sensitive Faders, Encoders, and RGB Pads

Nine 2-inch (50 mm) touch-sensitive faders, nine touch-sensitive encoders, and twelve pressure-sensitive RGB pads across four banks give you complete hands-on command. Touch sensing lets the screen preview the exact fader or knob under your finger before you move it, keeping mixes and automation precise. The pads read strike velocity and afterpressure for dynamic, expressive drum and clip work rather than a stiff feel. The whole surface delivers tactile control that mouse-driven editing simply cannot match.

Chord Play, Scale Mode, and Arpeggiator

Arturia's creative modes — Chord play with smart voicing, Scale mode, a multi-mode arpeggiator, and Hold — are built into the Ultra just like every mk3 KeyLab. Chord play sounds full voiced chords from one key, and Scale mode keeps notes in key to speed writing for players still learning theory. The arpeggiator, with five octaves to work across, spins held notes into wide evolving patterns you can shape live, while Hold runs them hands-free. These tools shorten the path from a quick idea to a finished, moving part on the hardware itself.

Analog Lab Pro Integration and Universal DAW Control

The KeyLab 61 mk3 Ultra is engineered around Arturia's Analog Lab Pro and the V Collection, auto-mapping its controls and screen to thousands of instrument presets. It also speaks standard control protocols to command the leading DAWs and stores up to six custom presets for other rigs. That integration means browsing, tweaking, and mixing happen without manual mapping from the moment you connect. For the comparison shopper, it is the flagship five-octave mk3 experience with a finish that makes a statement.

Connectivity and Who the Ultra Is For

The Ultra runs on USB-C bus power for a single-cable connection with no external supply, and adds five-pin MIDI DIN In and Out plus a sustain/expression pedal input for hardware synths and hands-free dynamics. First-time buyers get flagship five-octave control and approachable creative modes in a finish they will want on display. Upgraders gain the extra range, aftertouch, and touch controls in one move. And for the player who wants top-tier control paired with a bold identity, the Ultra Orange 61 is the centerpiece a rig is built around.
