Play pause Cubase and iOS at the same time

Hi,

Let say we have a music-playing app and have loaded a song to play. Also, assume we have a Cubase project with an audio track armed for recording.

I would like to trigger playback on both (DAW and the iOS app) at the same time. I have several midi and Bluetooth controllers that I can use.
Any help would be much appreciated.

PS. If you are wondering why I need this is as follows: I would like to playback a song and record (via playing on my controllers) various instruments in the song. I know I can record move the recorded take in the project arranger window. But I would rather do it without that.
