I have a CN37 and would like to use it in to accompany my flute playing in practice. I have the piano part as a MIDI file, and using the USB interface I can get the piano to play it. But it is awkward to look for and press the Play button and then get ready to play with my flute. Is there any way to press Play remotely, e.g. using my iPhone? The Virtual Technician does a lot of other things that suggest it should be possible.
