IK Multimedia has years of experience making audio products and software for the mobile musician. From microphone preamps to audio mixers and MIDI interfaces (and more), the company seems dedicated to its niche. The music device manufacturer has just announced a brand new entry, the iRig Keys I/O: a compact, travel-ready MIDI controller with a built-in 24/96KHz audio interface. It comes in two compact models; you can pre-order the 25-key version for $200 and the 49-key configuration for $300 right now. The final release is set for October of this year.
