Audio Interface Mode
Currently it is only possible to monitor audio coming in over USB in sample mode. It would be awesome if the OP-Z provided a mode or setting such that the headphones always monitor the audio coming in over USB, rather than the sound produced by the OP-Z. Sound produced by the OP-Z would still go out over USB.
This would enable, for example, applying effects to OP-Z’s audio or mixing with iOS instruments on an iPad and monitoring the output from the OP-Z.
This mode would be especially valuable in the context of newer iOS devices that do not have a headphone jack, where it is currently impossible to use OP-Z with iOS effects/instruments without an audio interface (and even this is complicated by iOS’s limit of one USB audio device at a time). Audio interface capabilities would make OP-Z and iPad an even more amazingly powerful, and much more portable, combo.
