Is your feature request related to a problem? Please describe.
Currently the transmitter includes a fully-featured playlist system and outputs redstone when playing a song. However this means that there's no way to trigger the transmitter to start playing outside of the UI.

Describe the solution you'd like
A block which can select a single MIDI file and play it when powered by redstone.

Describe alternatives you've considered
I can't think of any?
