It was once said to me by someone "If the number ends in SQ,QS or CD-4 then it's quite obvious what they are. And if it ends in QD it's EV-4, it's that simple."
It's that simple.
Except, there was never clarification as to what the status was with QS in regards to Project 3. What the deal is with the stickers. And the argument that, you need to go by the label, ignores the fact that no QS catalog numbers exist, while QS stickers clearly exist, implying there were actual QS encodings.
But now that we see some real evidence that Project 3 was just slapping QS stickers on EV4 records, because they considered them to be compatible, which means that, perhaps that statement was right all along. If it ends in QD it's EV-4, it's that simple.
But that leaves me with the question of.....where did the data in the quad label listing come from?

According to that list, 5051 is the last EV4 release. But QS releases continue up to 5080. However....I do have a copy of 5062, Tony Motolla - Superstar Guitar, which has a QD on the label, and a generic 4 channel stereo sticker on the cover. Which suggests EV4.
My guess is that at some point they stopped referring to EV4 and pushed them as QS more as time went on, so at a certain point they stopped being marketed that way....but I'm wonder what data, or listings, or source, that list was compiled from, to go back to look at those sources and see what further insight that might offer.
Because I also can't help but wonder, what titles have different mixes? As we've found with many of these, the QD records often have different quad mixes from the later SQ/CD4/tape releases, that's certainly the case in permissive polyphonics. But do all QD releases have a different earlier mix from the later SQ/CD4/tape releases? Or at some point, do the QDs contain the same mix as the later encodings?
