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

Correct. We have a wet/dry code in the works too!


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.

The WH-1 runs on completely different hardware. To transfer the algorithm (with our current knowledge) would be impossible.
It's within the realm of possibility to run both in the same box and then use a controller/mod to switch to the WH-1 signal path.

Your issue with the WH-1 sounds like a bad connection to RAM.

Hello.Is the wet/wet bin for the 27001 chip or just the wh100 rom that needs to be compiled with the rest?
How is the wet/dry coming along?

Just for the XP-100. If you know how to use a hex editor, it's a very simple task to either stick the bins together or to replace the old XP-100 code (it's at the beginning of the combined file). Otherwise, I can do it for you.

That's weird... I was convinced I had released it already.

I'll check out my bins and see if it's ready for release. I made the code modifications successfully, but there are a couple more steps before I can put it online.
At the time that I discovered wet/dry, I was basically hitting random buttons with regard to making the mod. I've since found out what most of the instructions do and now I'm more sure that it works and is stable.

That's good to hear. Maybe I overlooked it. I just now got around to installing the XP-ALLin rom. I took a bit of a break the last year. Today I started looking into Diptrace to learn how to make a PCB that incorporates the PIC for the momentary switch so I can ditch the rotary and relay. I don't know if you guys have messed with that yet.

I found this flash eprom board on oshpark. I wonder if that guy got around to doing anything with it.

XP100 modded dry/wet

As before, it's a txt so you may need to rename that for whatever flashing tool you may use.

Pretty cool. I considered doing something like this but by making a foray into the world of WiFi. I thought it would be neat to be able to flash the chip in my XP100 while sitting at my PC. The XP100 would power whatever networking chip it was (probably ESP8266). I was doing a lot of chip flashing back then (with my DIY programmer :icon_mrgreen:) so it could have been worth it.
