Cheers for the extra info, Robin. There seems to be a bit of confusion here (maybe just in the terms used) - but...
Whilst the 8-channel multi-track tapes are 1", what we're interested in here is the final stereo mix. Usually in those days you would mix down onto 2" stereo tape (running at 15ips) - maybe on a Studer or Revox reel to reel machine.
In my experience - the EMI and Island Tape Archives for
Ultravox, and John's personal Tape Archive which includes all of the material retrieved from Virgin Records - I've never seen anything to suggest that a 'final mix' was ever put onto a two inch stereo tape. Please note that this includes all of the material produced by
Ultravox when they worked with
Sir George Martin at Air Studios in the UK and in Montserrat when they recorded their
Quartet album.
Certainly, there are no two inch tapes which coincide with anything recorded at
Pathway Studios - the largest format used there was one inch tape.
Once they were happy with that mix, usually you would make a couple of "safety copies".
Or, alternatively, you might mix down simultaneously to two machines in parallel, as a safety measure (less likely in a tiny studio like Pathway).
One of these would be sent to Virgin's mastering engineer, who would tweak it so he could cut it onto vinyl (probably making a 'production master' tape in the process).
Early CD issues in the 1980s were often made from these production master tapes (which had already been tweaked for vinyl)... (as well as being maybe 2 or 3 or 4 tape generations down from the original mix)
When we did the EMI Gold CDs for
Ultravox back in the late nineties it was the 'production master' tapes which were used. The subsequent double-disc Definitive Editions went a generation closer to the 'original master' tapes.
That was when we discovered that another tape had been struck from the original one inch multi-tracks
You don't "strike" a stereo master from the multitracks (i.e. in the sense of making a kind of perfect copy of them). On their own, the raw multitrack tapes wouldn't sound much like the finished Metamatic album. You have to feed the multitrack tape through a mixing desk, ride the faders, mute things, apply all the effects (reverb, phasing, echo...) to create the mix that goes down on the final stereo mix tape. It is a creative realtime interactive process, and in those analogue days, would never give exactly the same results twice!
You're right - sorry, I didn't made myself particularly clear - the accepted practice once everyone was happy with a mix, would be for that to be committed to tape - and that would be regarded as the 'Original Master' / 'Final Mix'. The problem I have here is being able to confirm (without any doubt whatsoever) whether the tape used for the 2014 remaster is the same generation as the 'Production Master' (which is the version everyone is familiar with) or if it's the tape from which the 'Production Master' was itself created as none of the tape boxes are definitively labelled either 'Original Master' or 'Final Mix'. However, the dates on the box very strongly suggested the latter - but as I'm sure you'll appreciate any number of things could've happened to the tapes and their boxes in the intervening thirty-odd years.
So, I'm wondering if the recently unearthed tape was the original master mixdown tape (i.e. the highest generation grandaddy of all subsequent copies, with the least hiss and distortion).
Or it could just have been a safety dub copy, in which case it might be worse quality!
Or could it be an alternative set of mixes, different to the ones sent to Virgin to release? (If so, that would be pretty obvious on listening!)
Based on all of the information we had available, we believed that the tape we had identified was very likely to have been the 'Original Master' - and on that basis we had it transferred. We were all very pleased with the initial results - and that was before any remastering had been done. These are definitely not different mixes.
For what it's worth, I think that the most important thing here is how good the final result is. Personally I don't think that
Metamatic has ever sounded so good.
