K Multimedias PowerBridge works by continuously charging your iOS device as it delivers audio and MIDI information to your favorite recording and virtual instrument applications. Lay down your rhythm tracks with the iRig PADS using the Micro-USB attachment, then change out the PowerBridge adapter to the Mini-DIN connector and use iRig KEYS to record synth parts or piano tracks. Use your iRig hardware and your iOS instruments and DAWs to write, play, record, mix, and even distribute your music - the PowerBridge from IK Multimedia will keep you powered through it all.
