It looks like it has standard 1/8" in/out jacks. I wonder if it would take analog stereo input and output too. That would truly make it handy. But if it's only for MIDI, the device seems too specialized. There are other products on the market, like the Alesis iO dock (which obviously is a bit bulkier) that allow for MIDI and audio in and out. That seems a better investment, IMO.
It's very likely only for midi, and those can not be standard stereo 1/8" TRS... midi carries 16 channels in & out... probably can't do that with analog TRS (tip-ring-sleeve).
No drivers? What this means is that whatever driver this midi device uses is likely part of the USB Standard driver set, which iOS devices support. Therefore, it is very likely
any USB-MIDI device will also work just as well along with Apple's CCK, so long as it only requires the USB Standard drivers... and MIDI is pretty simple, so it shouldn't need more than that.
Third parties will try to make iOS device specific stuff... but they will have to really on what USB drivers already do for us on iOS. For example, any USB driven ADC, that supports the world standard USB stereo protocol will probably work with an iOS device and the Apple CCK. So we don't need to repurchase these iOS specific devices (like the guitar connection kit, etc.)... we just need Apple's Camera Connection Kit and external devices that are driven by the standard USB driver set (which we likely already own because we were using them with our laptops before we got iPads).
