IK iRig Keys 2 Pro – 37 Full-Size Key USB/MIDI Keyboard Controller for iPhone, iPad, Android & Mac/PC

The iRig Keys 2 Pro is a 37-key USB/MIDI keyboard controller with full-size, velocity-sensitive keys, made for keyboard players, songwriters, producers and students who want a real piano-sized keybed in a controller that still fits in a backpack. It connects to iPhone, iPad, Mac/PC and most Android devices, and controls hardware synths through its MIDI ports.

Full-Size Keys in a Portable Body

Mini-keys are easy to carry but hard to play with proper technique. The iRig Keys 2 Pro keeps standard-width keys across three octaves, so chord shapes, fingering and hand position feel the same as on a piano or a larger controller. The body measures 605 x 212mm and weighs 1.87kg, which is still light enough for a laptop bag or a small desk.

Connect to Phone, Tablet, Computer or Synth

A single micro-USB socket handles every connection. Lightning and USB-A cables come in the box for iPhone/iPad and computers. IK lists it as compatible with most Android devices; Android and USB-C devices need a micro-USB to OTG or micro-USB to USB-C cable.

The 2.5mm MIDI in and out jacks, with a MIDI adapter included, let it play analogue synths, drum machines and sound modules without a computer, and stand-alone mode suits outboard rigs.

Built-in Headphone Output

Newer iPhones and iPads have no headphone jack. The iRig Keys 2 Pro adds its own 1/8″ headphone output with a volume knob, so you can hear your app through headphones for silent practice, or feed small speakers. Its D/A works at 16 or 24-bit and up to 96kHz.

Hands-on Control

• Pitch bend and modulation wheels for expressive leads and pads
• 4 assignable knobs with a 5-8 button, giving 8 parameters for filters, effects or levels
• Push data encoder for browsing presets and editing values
• Octave and program up/down buttons
• SET button to save and recall custom setups
• 1/4″ pedal input for a normally open sustain pedal or an expression pedal

Power Anywhere

It runs on USB power from your computer, phone or tablet, a USB wall charger or a USB battery pack. It draws very little current, so some power banks may switch themselves off; for stand-alone MIDI use from a battery pack, choose one that stays on under a very light load.

Software

The iRig Keys 2 series has shipped with IK’s SampleTank SE workstation for Mac/PC (listed by retailers as SampleTank 4 SE, with more than 2,000 sounds), and it works with hundreds of iOS, Android and desktop apps that accept MIDI input.

Who Is It For?

• Pianists and keyboard players who want full-size keys on the go
• Students learning chords and fingering on an iPad or laptop
• Songwriters and composers sketching on mobile devices
• Synth owners who need a compact full-size controller for a hardware rig

It is not a weighted or hammer-action keyboard, so it will not replace a digital piano for classical practice. Some performing players also find a 37-key range limiting on stage.

iRig Keys 2 Pro vs iRig Keys 2 and iRig Keys 2 Mini

All three share the headphone output, MIDI I/O, knobs and setup memory. The iRig Keys 2 has the same 37-key range with mini-keys in a smaller 518 x 139mm, 0.87kg body. The iRig Keys 2 Mini has 25 mini-keys and drops the wheels and pedal input. Choose the Pro if playing feel matters more than size. For a controller with a built-in audio interface, look at the iRig Keys I/O. Compare options in our MIDI keyboards range, or browse MIDI controllers.
