    I'd be interested in the Femmes (saw them in '89 or so, GREAT) and in JGB '78 (I don't think that is MORE '78 because there hasn't been a first JGB '78 vine, or have I missed something?). Oooh, and Dire Straits would be nice too. Good stuff, Lopezz!

    Speechless, I'm literally speechless. And I was going to ask if anybody had any T.Heads shows, and the only tape I ever had (it's gone now, though) was a Violent Femmes show from a frat party at the University of the South. I'll PM you, see how it gets started.

    Vining Possibility?
    I am looking to see if there would be any intrest in a flac/shn vine. I have a lot of shows that I would like to share if any one wants them. But its too much for one person to vine. My idea was, a flac/shn vine. Vinners with flac capabilites could copy the ones they want. And if they want to - make audio cd's and start a vine for the flacless. It would be a huge vine(15 dvd's) but you would only copy the ones that you want and pass it on. I you want to start a cd vine, great! If you dont, no biggie,someone else might. No rules, no expectations, I would like to keep it lose and free. Vinners that can use flac and might be interested PM me. I can put it together(might take a week) The concerts I have are all good quality, I discard them shortly after I get them if they dont make the cut. I have around 6 to 10 shows of each. JGB 85 More JGB 76, 78 More Old and in the Way More Reconstuction Pearl Jam Dire Straits U2 Jefferson Airplane Neil Young Crosby Stills Nash Young Bob Marley Garcia and Freinds Phil and Friends Some of these I only have 1 or 2 shows: Talking Heads Sublime Violent Femmes Grateful Dead Studio Outtakes 71-77 A Grateful Dead Movie of 10-31-80 (4 dvd set)

    Yep, that works, thanks Hal, don't know if it saves any time as I still had to create a folder and copy and paste into the folder, but it seems a little easier than importing track by track into I-Tunes. What if I want to burn the FLAC files onto a DVD, in case I want to pass lossless files onto someone else? How do I do that? Can I do that directly from My Computer or do I need to download something else? I have a DVD burner. Thanks!

    My way is to decode to the the same folder that the flac is in and then just go to add folder to library in itunes and add the folder, that way you don't have to add track by track If the doors of perception were cleansed, everything would appear to man as it is, infinite. William Blake

    I think I figured it out. I downloaded Trader's Little Helper a while ago and finally tried it with the 1991 Digital SBD vine. I use Windows Vista and I-Tunes. Let me know if I am doing this correctly (i.e., can I combine any of the steps). (1) Copy tracks from the FLAC DVD to the Music section of my computer. I have been doing it one show at a time. Maybe I could do the entire disc at once, I don't know. (2) Go to Trader's Little Helper, Decode Audio Files, and add the tracks to decode. I have been doing only one CD worth at a time, as when I tried to do the entire show, I get an error message. After it decodes, the WAV files appear in the Music section of my computer. (3) Import the tracks, track by track, into I-tunes. (4) Burn WAV disc on I-Tunes (5) After ensuring the disc plays, delete the FLAC files on my harddrive. I've been leaving the WAV files because I don't want them to disappear from I-Tunes (I think they might delete because the one time I converted Apple's lossless files, then deleted them on my harddrive, the WAV files in my I-tunes disapeared). I don't want the WAV files on my harddrive if it takes up too much space. Thanks for your help

    my thought on the Phil disc is that it would probably be a good thing to inquire over on phillesh.net about that, because while it's clearly not Grateful Dead per se I suspect it's probably got half a dozen copyright/rights issues going on (book publisher! music publisher! performance rights! etc.!) that, from this distance make me pretty nervous. If you want to PM me the specifics, I can pursue this with the Phil camp, or feel free to look into it yourself, but let's just say issues abound and we need more info. Thanks!

so lets keep the Hampton '89 Reseed vine on page 1, and delete the old initial Hampton '89 vine on page 2. (the reseed has the current offerings/additional shows, and deleting the initial vine will stop people from signing up on a non-functional vine). I should have seen that when I was cut and pasting last night but it was difficult to keep track. This is definately a more 'user friendly' presentation and I can actually see very now all the vines that are available. Again, thanks for your efforts with this new set-up.

FYI Bob, a couple of those shows you listed above have already been vined (5/7/77 and 10/16/77). Sidenote: The '69 show is from the run at The Ark in Boston. That is supposed to be a great run, though I have never heard any of it.

Thank you marye and yamadog. The PERRO sessions is what I was looking for. I do have the album you mention marye, it is an 80's continuation of Sunfighter, Blows Against The Empire and Ballad of the Chrome Nun from the 70's. I loved all that stuff. Had some awesome Jerry solos on Blows. Too bad Kantner and co. didn't follow this path instead of the more commercial Jefferson Starship one. They lost me after about the 3rd album. Oh well, they can probably retire comfortably. If the doors of perception were cleansed, everything would appear to man as it is, infinite. Wiliam Blake

I've listened to two of our vines in recent nights using iTunes. I'm pretty farmiliar with this program now and I'm pretty sure that on importing, I'm not adding gaps between songs. I even have the crossfade playback set to 2 seconds which should make the songs run together. Is there something I'm missing or did the vines come with gaps between songs?

I guess the first way to surpass this problem would be for every trader here to make sure they are burning the cds without gaps.I don't know about other players, but in iTunes the way to eliminate the gaps is shown below: Edit> Preferences> Advanced> Burning> *Gaps between songs=none We should all try to avoid this problem of gaps between songs. All things being equal, I would have to choose a tape with no gaps then a cd with gaps between tracks. Especially with a band like the Dead, I hate to hear a blank space in a segue between two songs.

I use WMP and I don't think there is a way to avoid gaps with it. Maybe I'll download I-Tunes and do what Operator suggests. BUT, if you rreceive a vine with cds with gaps, can't you eliminate them by the way Operator suggests. Or once a cd has gaps, it can't be eliminated?

dstache - I have WMP and the gaps too. I would like to send out some shows I have that were given to me and I have the discs with no gaps between and would like to copy these with no gaps between and send them out. Also would like the shows I listen to, either on CD or WMP not to have these gaps but I am so overjoyed at having the shows that gaps are not a major irritant for me. Just the next step to learn. I wish there was a basic guide to trading somewhere. There is a big learning curve for some of us and myself I would rather be out hiking somewhere than spending long periods of time trying to figure all this out. Thanks to all of you that have given me and other here pointers. Just this year I have learned how to rip and burn discs, how to download and am learning Trader's Helper and capturing streams. There is so much out there as far as music players etc. for your computer, it gets confusing. One of my friends who has 1000's of hours of tapes is overjoyed whenever I give him a show even if it is in mp3 (which I no longer do) or with the gaps. He just keeps pointing out to me how much better these are than our old tapes. So I am not going to whine about the formats I have now but will keep trying to improve the quality, but any guides for us Luddites would be appreciated.

Well, for instance a few vines came to me recently and the cds they were on had gaps between the tracks.When I imported them into iTunes, the gaps remained. So I think if we could eliminate the gaps pre-burning, the problem would be solved for everyone down the vine.

I know that my Cream Filling vine definitely had gaps as I use WMP. Sorry about that. I'll download I-Tunes as you recommend for future vines. And for myself. I'd prefer no gaps for sure. Just wasn't that big of a deal to me. Operator, you are saying that once there are gaps on the cds, there is no way for the person who receives the cds to correct that, right? So, you can't make the Cream Filling shows have no gaps?

I know there are a few applications with which to eliminate the gaps. I'm just not familiar with those programs, but I'm sure there are others here who are. You could just check the help section of WMP and see if they address this issue. When you received the discs did they have gaps between songs?

some shows with the 'gaps' between tracks and I have to agree with operator that those can be annoying and I plead total ignorance on how to rectify it on my end. I use a Nero burner on my computer and am a true 'technogeezer'. I would really like to know how to 'join' those that have the gaps, but don't know how to do it. These are shows that came to me like this and if there is an effective way to do it, that would be nice. It isn't as big a deal with my Clapton, Neil, Marley, etc, because those guys rarely segue as the Dead do. So I am part of the difficulty and I will attempt to make full disclaimer on the shows that I am vining that are in that condition. But it is kinda like with the Veneta show and its 'faults', I would rather have that show that is many generations down the line than not having the show at all. But yes, operator, to have those segues smooth and the be able to grin with delight as the boys slide into another tune or 'jump the tracks' to the next song are infinitely preferable to me as well.

the 5-26-72 and listened back to NFA>GDTRFB>NFA and there was no pause in between those tunes. (KILLER sequence btw) Those segue seamlessly into one another without any 'gaps'. My Nero appears to copy the source in front of it, just as it is. So if the source has gaps, then the copy will and visa versa. (Of course it 'marks' the different tracks visually so you can select them, but not with an audible break). So, I am going ahead to try to finish these shows and send the vine out. (My sons are finishing their semester papers so computer time is not at a premium right now.) As far as the other May '72 shows (5/4 & 5/11), I will try to work to see if I can 'join' those gaps, but honestly I am over my head with this. I have a kinship with Hal and just learned about alot of how to do this recently. I need a vine 'doctor' to be able to 'mend' those separated jams for us. I will try to do it, but if I am unsuccessful, then I will simply send the shows onto dstache. Maybe he (or someone on down the vine) will figure it out. But thankfully the 5-26-72 is 'intact' (thanks again, Richard) and it is a truly stunning show and a wonderful finale to the Dead's adventure 'across the pond'. That show alone is worth vining.

Hi guys-Richard has just started a Summer '82 vine which has a matrix recording included. I kind of understand the concept of "matrix" but I'd like to hear what other people know about the whole thing. Basically, as far as I can tell, a "matrix" recording, although I believe that to be a misnomer, is a mix of a sbd and an audience recording. Any other details we should all know? When did Healy start using this method for mixing? Any comments? I'd love to know some more.

Healy did not do the matrix mixes. Those are done by various folks who have secured an SBD and a high quality AUD tape, then blended them together. Check the source and recording info in the text files to learn more about how this was done.The theory behind this is to try and re-create an authentic live-listening experience. IMHO, some folks do a better job of this than others. I don't think it comes off as well in stereo as it does in DTS 5.1 surround sound. I have some of those where the mix has the SBD on the front and center channels and the AUD on the rear channels. When this is done well, the result is awesome. Regarding the Iowa show, I would love to have the straight SBD tape, I just haven't found it yet. So I vined the best of what I have. Hope that helps. Peace, Richard

Hi,I'm wondering if anyone is interested in helping me digitize some tapes. I have maybe 1000 GD audio tapes (+ several hundred other live band recordings) that I would love to have in digital format. The vast majority of the GD tapes are Maxell XLS soundboards. While the shows span 30 years, what I think are the best years are well represented (68-77, 85, 90, 91). I live in Chicago and the tapes are in storage in Northern CA. If there is anyone seriously interested in helping me digitize some of them, I can create a database of what I have and send it to you and we can talk about working out some kind of trade or form of compensation.

I have the same thoughts as Yama. I to have 1000+ cassttes and started to run them through various programs designed to take analog and upload it to the computer for future CDs (see my posts from this past summer). However, it is a VERY time consuming project and I have found it much easier to go online and download shows some of which sound 10x better then my copies. Thus, you already have the digital file and dont have to mess with the cassettes. Good luck! Eric

I got a good 500gb HD from newegg.com and went to town. I now have much more than I used to have and have an ipod chock full of tasty bits to satisfy the jones while I'm on the road.

Hey folks,Tonight I was trying to decode some shn files that I had decoded before and they kept coming up as errors and were not decoded. So I found that there is a new version of Traders Little Helper, downloaded it and now files are decoding fine. I don't get it, I don't understand it but somehow it works now.

Just stumbled into this topic. Because I use to have trouble with my iMac, I decided to read through all the posts. And as I already have had my share of trouble with mit iTunes dealing with gap's, (at least some of) the following might be helpful to (hopefully at least one of) you. I have used the path mentioned in a previous comment on "Gap's" to adjust "none" as the duration of silence between tracks. On my iMac I can use Garage Band to cut tracks into little pieces to juggle them around, delete and whatever. IMAGINE "three Dark full Star days" ... ) My Microsoft times PC doctor still runs his pc with Windows 98. And I have seen his WinOn software not only cut tracks into segments, etc. but also chose Nothing/none/0 as the length of silence between tracks. And that's for sure the same with newer Win On versions or other Windows sound software. The bad thing is that my iTunes had this siiod (Self Induced Ignoring Orders Desease) phase .... Although I had set it on "none", it started to make 2 seconds gaps on the copies. I checked and it said still "none". I copied an official CD with gaps, told my Mac to have "none" and it kept/made them. So I was glad, when, out of a sudden, with no changes, except usual uploads for my iMac software several times, It must have been the smell of all the Dead audio roses coming in, that made my iTunes decide to follow my instructions again. After I had added decoded flac files for the first time. So I am sure, the tools are amongst us, to shut the gaps up. PEACE andré

From what I understand, Healy was responsible for creating at least some of the matrix mixes that are in circulation. Here is what I was able to dig up online. If you're more interested, you can follow this link:http://www.thetradersden.org/forums/archive/index.php/t-5988.html This is an excerpt from that link. Super technical, but informative. 04-13-05, 11:46 AM :nono: OK, here we go again. What are commonly (inaccurately) referred to as "Matrix" recordings are in fact "Blends" of independently recorded SBD and AUD sources of an event. In the audio world, a matrix recording is in fact: Mid-side Matrix One cardioid mic (M) points at subject (0°), and a figure-8 mic (S) picks up ambient sound by pointing at sides(90° and 270°). The signals are then run through a decoder matrix (software or hardware) which creates two stereo channels: n M+S = channel one n M - S = channel two One channel is a mix of M and S and the other be a mix of M and Sø (which means S is 180° out of phase) n The more S, the stronger the separation. MS Matrix recording is mostly used in acoustic concert settings to capture the true image of the hall. One technique that Dan Healy perfected when mixing and recording the Grateful Dead, was to place a MS Matrixed microphone array at the mix position, and record it on a source that was locked to the same source as the SBD recording (assuring that the recordings were sped accurate to each other) What Dan called an "Ultra Matrix" was (as I understand it) actually a BLEND of a Matrix recording and a SBD recording. There are also time coincidence issues that are addressed when combining these sources. Many "Matrix" recordings in circulation are simply blends of 2 different recordings and present a significant challenge in Post Production in terms of correctly time and pitch aligning the sources. The results of these efforts often sound really good, but are difficult to produce. The cow has left the barn in terms of correcting the proper use of the term "Matrix", but in fact, it's nice to know the proper terms to apply to these very different methods.
