Synths In A Dark Room

This has bright, flashing lights.  If you are sensitive to that sort of thing, I would recommend not playing.

An ambient experience in Unreal Engine 4.  Balls of light float around you as they play procedurally generated sounds.   Choose the beats per minute, chord progression, and number of synths.  If you just want to open it and turn it on there is a default chord progression that will play if you remove all the chord dropdown menus.
