Well I was about to post the same thing... I would like to know about alternatives in case sonicport keeps this way. The problem with Irig and other interfaces I’ve seen is that they not allow for a stereo line in input... and that is just what I need since I use it to record audio from my Yamaha keyboard. Any one has any experience with other interfaces that allows stereo line in input? So far the closest I have seen browsing in the web is a usb class compliant Yamaha mixer connected through the camera connection kit 3. But this is much more than I really need. Waiting for your feedback!
