thoughts on Digitech Space Station eprom copying?

[digi2t]

OK folks, try this. If you're using the double wafer switch, as per the build document, then swap A15, and A16 wires.

If you've followed the numbering from the build doc, then put A16 on pole 12, and A15 on pole 18.

Try that, and let me know what happens. I've just taken a long hard look at my unit, and it be that the connections may be misrepresented in the build doc.

Also, you should not be getting more than 5mV of leakage to a pole that is not in use. I tested all the poles on my switch, and I had one pole at 5mV. All the others were either 5V, or zero. If you're getting 0.41V, then I would check for bridges, or worse, a faulty switch.

Well, I'm happy to report;

IT'S ALIVE!!!!!    Swapping those pins did the trick.

All modes working, all patches showing up where and how they should. (A bit more latency in the xp-100 mode than the other patches, but that's a smaller issue for another day). I forgot how awesome and inspirational the xp-300 is! Mine was stolen from my studio a few years ago and I now finally have a replacement along w/ the rest of the xp-series thanks to you all. Especially digi2t!! Thanks again!
I'll upload some pics of the finished build this weekend.

Well.... this is where I must "eat crow", and admit that I erred when I wrote the document. A minor error, but with major implications.

I've updated/corrected the build doc, and I've uploaded it to the Gallery. The link is;

This should conclude that marmaliser's board is fine, and there shouldn't be any more XP-ALL+ build problems of the switching sort in the future.

I'll conclude by offering my profuse apologies for the error. Albeit a small error, I know it's caused big headaches for some. What can I say, shit happens, but at least we got to the bottom of it.

Maybe now I can convert G_L to a + version?

Some day brother.... some day!   

BTW.... I think I can speak for everyone here and say that there is no apology necessary! If it wasn't for you and your trailblazing..... none of these mods would have happened!!! 

[Mojsisije]

I'm very glad to see this happened, I'll go and snag mine from the workbench and see if I can make it live again!

If you were having the same switching problem, then swapping the A15/A16 wires at the switch should fix it. I thought that when I wired mine, that I did so sequentially with the switch numbering, and drew it as such. Apparently, this was not the case. 

Be sure to dispose of the old build doc, and download the updated one.

Already downloaded the new one, thanks. I'm still reluctant to call this a victory for me though as I've tried something similar while doing the initial build because I saw some anomalies with the switching, but didn't really give it much attention. I'll post back once I have it done, sometime tomorrow I believe.

[Mojsisije]

Yup, that did it, it works. I got a small heart attack at some point because it didn't go to the space station mode but got stuck in reverberator mode, then I realised I was too excited to properly solder everything and the common lead fell off.
Marmaliser get in here and do this, you've got a space station waiting for you.

Now as soon as I find my arduino board, I'll get around to making it all true bypass and switchable via the bypass switch, so stay tuned.

[digi2t]

Don't forget everybody, please do a reset and calibration after the mod. This will ensure that everything works properly.

Great news, thanks to all.

Did someone shout me
I now have one fully working XP100 to XP All + (although slightly battered and bruised from all the things i tested so need to tidy it up).   The other XP100 to XP all was behaving erratic and then I realised that the connection to the R30 SMD resistor pad had come off with all the messing around.

When I started out with these mods I hadn't realised that I was the first to attempt them from build docs so wasn't expecting the teething problems that you would expect with a new set of Docs.  I learnt a heck of a lot.

Digi2t an Gvt Lacky I am truly gratefull, those XP300 tonaz were worth the effort.  Honored also to have my board in the build docs

I now have a XP200 arriving today and some more adapter boards on the way from OSHPark

If anyone in the UK wants an XP All chip burning or anadapter board drop me a PM

Thanks again

You're very welcome bud. I'm just super happy that everything worked out. I'm VERY grateful for the efforts, and input from Mojsisije, OptiMitch Prime, and yourself. Without you guys pushing my buttons, I may have never found the wiring error. Tip of the community hat there. Actually, it just occurred to me that I never asked your permission to publish your board in the build doc... Sorry. I'm glad you approve though.

That's super kind of you to offer the service. Class act, all the way!

My XP200 did indeed arrive today and before opening her up I tested it and the pedal made no change to pitch / speed / volume whatsoever.  Thought the worst and then remembered your words re calibration.  Bam 20 seconds later its working.

If I had a dollar for every one that I picked up sold as "Broken" and this happened.........

I'd have at least 6 or 7 dollars!

Hello all,

I just joined this site because I'm looking to get one of these pedals for my son this Christmas. He is very interested in playing music and guitars and stuff and has started getting quite a few pedals in the past couple years. One of his favorite bands Tera Melos uses one of these pedals and he's been going nuts over it. I've been researching over the past week to see if I can get one for him but noticed they are pretty expensive. I emailed a couple people but haven't heard anything and have been stumbling deeper into these kind of forum sites.

Anyways long story short I wanted to know if anyone here would be willing to build one if I bought and shipped the necessary parts to you and had it shipped back once complete. Obviously I'd pay you for your time and work. I also understand if this kind of thing is frowned upon to ask for here so if that's the case just let me know and I'll go and look around at other places.

Thanks!

Spencer.

[fastatlast]

I should add that he's looking for the space station pedal, not necessarily the 4 in 1 mod!

Hello everyone,

I've just registered and am really happy to have found this thread/topic. I've been hunting for the SS at an affordable price for quite a while now but it seems impossible to get hold of one here where I'm living (Poland).
The good news is an XP200 Modulator is up for grabs at a very good price, so I'm thinking of doing this mod to an XP300 myself. The thing is I'm not an electronics geek and would need the help and guidance in this process. I'm not interested in neither having both XP200 and XP300 in one box, nor the XP1000 (XP-all). All I want is to have the SS.

Is there anyone out there willing to help me out, specify what parts/things I need to buy and where to get the SS program for the chip?

Would be much obliged.

Cheers!

Philip

@PhilipP

Send me a PM and I will give you the details. 

[marmaliser]

Thanks Greg. Philip as PM'd me and supplying him with an XP300  is no problem. Nor anyone else in EI for that matter
