We have installed a bluetooth device in the stereo in MTG.01. This means that you can play audio files from any place in the room without being tethered to the stereo cabinet. As a matter of fact, the cabinet can just be against the wall! This video explains how to set-up your devices.
Note: I have found the "Pro Metronome" app to be inaccurate when played through this system. However, all other apps seems to work quite well, including synthesisers and Garage Band.
GARAGE BAND USERS: You will want to see my instructional vid on using GB to record ensembles and playback. (Not Yet Available).
