An ambient-ish MIDI, created for Freedoom's map "Main Control" (pull request). It's a sprawling base, but strangely dark and empty. Notes are repeated to create a delay effect, a trick I learned when importing one of Freedoom's MIDIs into MuseScore. Apart from Freedoom, use this for areas that are empty and abandoned, perhaps with a sinister atmosphere.

Attribution is not required, but appreciated. Also, check out Freedoom, it's a great game!
