I've been looking at options to have a quality live recording of audio from the PX-5S appear in a DAW, like Garage Band or Logic Pro X. This will be connected to a Macbook Pro Retina, if it matters. Has anyone looked into the Presonus Audiobox iTwo? It sounds, no pun intended, like it's up to the job, but I haven't found any reference to people using it with a keyboard. Unbundled, it can be found for about $160 US on Amazon. One review: http://en.audiofanzine.com/external-audio-interface/presonus/audiobox-itwo/editorial/reviews/mac-pc-or-ios-this-interface-has-you-covered.html Downloads: http://www.presonus.com/support/downloads/AudioBox-iTwo-Studio Two concerns: - Can it accept the line outs from the PX-5S (TRS vs)? - Does it only work with the Presonus DAW (includes the crippled 'Artists' version)? Ideally you connect the MIDI input/output and the line output from the PX-5S to the unit, USB to the computer, the output connects to your speakers, and everything plays nicely together. Has anyone tried it? Thanks. Peter
