I eventually made it home, though, and wrestled the thing into the house myself. The first thing you notice about the Optigan (if you have any imagination at all, that is) is how malleable this technology was. You can do all sorts of things with the discs to sabotage the sound- put them in upside down, put several in at once, manually stop and start them with your hands for record scratch effects, press all the buttons at once, and so on. Most of the sounds that were recorded for the keyboard section are different kinds of sustained organs. Since the disc spins constantly, the sounds just keep looping around and around. So the keyboard sounds can't have a beginning and end per se. (Something like a piano sound wouldn't work because a piano has a percussive attack transient followed by a slow decay. On the Optigan, you would just get a piano note striking over and over.) The drums and accompaniments keep looping as well- if you want to start on the downbeat, you have to keep watching this little flashing metronome that blinks red at the beginning of each bar. Otherwise you can cut in and out of each loop whenever you want- the buttons just turn the sound on and off.

Since any sound could be encoded on these discs, the organs are actually pretty nice- big Hammond B3's and Mighty Wurlitzers. The drums are often pretty beefy sounding, though "lo-fi" is definitely the phrase that comes to mind. The rest of the accompanimental instruments usually sound kind of claustrophobic, but again that's part of the sick charm of the instrument. Some of the discs even have non-musical sound effects (such as applause) on them.

You would think that, since the discs are not played by physical contact, there would be no pops or scratches such as on vinyl records. But this is not the case- tiny scratches on the discs cause irregular defractions of light which in turn end up sounding exactly like record scratches! Most of the time, though, this actually improves the sound. You get the weird feeling that you're listening to a cheesy old Enoch Light record but that you're actually controlling where the music goes!
