No, not that organ
Back in the dark age history of early computers, programmers figured out that they could make a mainframe's front panel lights blink the meter of songs; soon they realized that they could make the magnetic tape drives "sing." In this case, the the computer is a PC with two 3 1/2 drives, and two 5 1/4 drives, interfacing with a MIDI device. The "organ" can make four simultaneous notes via the four drives; each drive has a different range and timbre. In the video below, the organ performs Bach's Toccata and Fugue.
