XP-ALLin - the latest and greatest in the XP-ALL project.

All your fault pal.

:kicksrocks:     

The good thing is that sales appear to have stagnated. I see the same units for sale for the same prices for weeks on end.

Only a waiting game before the prices go down... hopefully

I bought mine for about $170 equiv. including postage and tax (cheapest to buy from the UK). Then 2 months afterwards, I saw a unit that had faulty buttons to bid on for £1. I'm reminded from this price discussion that I probably could have won it and I've been kicking myself ever since ((

I wonder who bought that one    Went for £21 in the end.  I have replaced the buttons with foot switches and made  a face plate like someone did on here.  Halfway through the conversion to XP ALL +

Update:

I have found how to modify the XP100 ROM to output in stereo! The only thing is... it's wet on both sides. I don't know how much you guys would care about having that?
My feeling is that getting wet/dry stereo out would require much more understanding of the DSP chip than I currently have. My greatest progress so far has been seeing the 4-byte instructions and the 3-byte data words that are sent to the DSP. Without info on the DSP's instruction set... it's somewhat impossible to reprogram it.

I 'discovered' this mod 3 weeks ago now but held off on an update until I heard a word from Dino. What you doing man?? 
Edit:  Turns out I didn't email Dino! Now I blame Greg for not telling me my mistake  Haha

Trivia:

• The mod to get wet/wet output is a change of a single bit
• The XP100's tuner mode's volume pedal is stereo wet/wet from factory because...
• All units contain the same data to send to the DSP in tuner mode

All right, I've been wanting to do this for a while and just picked up an XP100 yesterday.  I can't wait to get started on this, in the very early 00's my other guitar player had a Space Station that he never used so I had it on my board for three or four years and I really miss it!  Been looking to come across a cheap XP ever since you guys started this, there are two things I try not to order online and be zen about finding, used pedals and LPs, it's almost as much about the hunt as it is owning it.

I'm really looking forward to this!

Those of you that happen to have an XP kicking around... be thankful.

Used to be able to pick up a second hand XP100 or maybe even 200 for about $50-70. Can't touch one for under $150 now 

[charmonder]

Did you already post the bin file for stereo wet/wet XP100? Personally I would find that way more useful than dry/wet, thanks!

I got mine for $100 at Sam Ash, I figured that was fair enough.

Hello y'all! I should really enable notifications...

I never uploaded/finished the wet/wet binary because of lack of interest. Now that a couple of you are here, the XP100 modded wet/wet can be found here:

https://www.aronnelson.com/DIYFiles/up/xp100_whammy_eprom_new_-_mod_%2B_wetwet.txt

The file extension is txt because I wasn't allowed to upload .bin
Please do report back if this worked correctly - I have my own testbench but I don't trust myself!

I am still investigating the mystery TMS57070 DSP chip. Yesterday I found a way to get all 3 XP100 effects on the pedal at the same time. Cool stuff.

[charmonder]

Thank you! I'll report back as soon as I can.

So I just ordered the OSH park PCB for the conversion.

Do any of you folks that have done this already have a reliable/preferred source for the ram and eeprom stuff?  I'm not super fond of ebaying chips.

The EEPROM chips I have used many different vendors. My RAM chips I used to get from a specific eBayer but sadly, they have been "away" for several months and I fear that they will not be back 

Kinda bummed because they had great prices and I never got a bad chip from them.

[Prehistoricman]

I bought 5 chips from https://www.ebay.co.uk/usr/cayin35
All of them worked but one of them was slower than the rest. Not a big deal especially when you get 5 pieces.
Sadly for you, I don't think they deliver to the US.

Check out the Dead End FX store. We offer the adapter boards, as well as an EPROM burning service. I test all EPROM's before shipping.

HOW DID I MISS THE ADAPTER BOARD ON YOUR PAGE!!!!

I was planning on using your chip burning service and even though I love OSH Park I would have rather given money to you!

That's ok, there's more boards I'll probably be buying from you when I get the chip.  Any idea on the ETA of the Meaty Balls, I'm in love since I repaired one for Steve West (Pavement/Silver Jews), I didn't want to give it back.

Meaty Ball have been ordered and should be here in a week or two.

Question on the wet/wet code. Does it also contain the preset memory mod of the XP-ALLin code?

This is great news, sounds like about the time I'll be getting chips and mailing them to you.

Yes.

So, with this code I no longer need to stuff the relay on the adapter pcb?

Got everything but my adapter pcb's (I think they shipped, I'm bad about going to my mailbox) so I'm going to start on this soon.

Crazy idea, but is there any way to do the WH-1 code for the Whammy part instead of the XP version, I've got a 3/4 working one (white noise follows the notes, I think there may be some corruption going on) and there's just something about it that seems better than the others I've tried.  The whammy just doesn't suit my playing style, but after playing the WH-1 I could see using it.
