IK Multimedia has announced iRig Keys 25, iRig Keys 37 and iRig Keys 37 PRO. These three new MIDI keyboard controllers are specifically designed with mobile Mac and PC musicians in mind.

Each one offers a different keyboard layout and size: iRig Keys 25 comes with 25 mini-keys, iRig Keys 37 comes with 37 mini-keys and iRig Keys 37 PRO comes with 37 full-sized keys. All three come loaded with all the features and controls required for portable performance.

All three keyboard controllers come bundled with SampleTank 3 SE, a special version of the sound and groove workstation for Mac/PC. It features an expandable 6.5GB sample library with instruments in categories that cover everything from acoustic to electronic and beyond.

When users register their keyboard controller, they'll also get a spread of free instrument collections. These collections include The Grid, a collection of electronic construction kits and drum kits plus five instrument collections of the user's choosing from IK's electronically focused Beats and Elektronika series.

iRig Keys 25 is available for $59.99, iRig Keys 37 for $79.99, and iRig Keys 37 Pro for $99.99 from music and electronics retailers and from the IK online store.
