I had one of those in my car. 4 tracks per pass were used in quad mode so each side of the album played without a track switch. When it was stolen(along with the muscle car) I was heartbroken. I had a few quad tapes including the aforementioned The Six Wives of Henry the Eighth. I also had Dark Side of the Moon(surprise surprise) and Zappa's Overnight Sensation and a few others. Drive to the woods roll down the windows then imbibe and pop in quadraphonic Pink Floyd. Boy we had some fun before we hunkered down and invented all the technology we see today.

I also used CD-4 records at the time. the front-back difference subcarrier was up at 18 kHz to 45 kHz. Who ever thought that a record's frequency response could go to 45khz? The Door's Riders on the Storm had whispering of the tag phrase "Riders on the Storm" isolated in the rear channels. If you listen close to the stereo version you can hear the whispering. I also had some classical recordings with 2 mikes at the rear of the hall in the rear channels.

Anyone who poo-poos quadraphonic should rethink that opinion when they fire up a movie with a 191.1(or whatever the current max is) speaker set up.

Thanks for the great memories you just triggered. I needed that!

I don’t know where it is now, probably lost, but I had a JVC quadraphonic 8 Track player. It could play regular 8 Track, which involved playing two tracks on the first loop and the other two tracks on the second loop, or it could play the four tracks in one loop. I only had a few tapes for it, one of those was a special recording of The Six Wives of Henry the Eighth, by Rick Wakeman.

> True, reading the media file takes a bit more time than a clip already in RAM with the rest of the stack file.  But in many cases it's not noticeable.  And where it is noticeable it probably has less to do with the file I/O than the codec itself:  HC's SND resources had few compression options, and MC's audioclips were limited to .au format, which IIRC isn't compressed at all.
> It might be nice to see LC expand the internal clips options to support the same range of formats/codecs the Player does. But even then it would be limited to smaller files where it's practical to load them all into RAM with the rest of the stack file, modestly useful for some projects but prohibitive with longer files.
