Just to check I haven't missed anything: Is there a way to run BIAB on iPhone/iPad in the background? If I start playback in BIAB on my iPad and then switch to another application (iBooks in this case, to view the score in a PDF document), the audio output from BIAB stops.

Other apps on iPad/iPhone (e.g. AmpliTube) has an option to enable background audio, but I can't find anything like that in BIAB.
