Stage II factory patches are garbled after update.

Hi,
I have updated a LP Stage II to v3.1 672 from v2 and all the patches are garbled/garbage. I also can’t program new patches on the LP. I followed the directions at the begining of the “New Firmware v3.1 …” thread to update from v2 :

However, I found myself with the corrupt patches so I updated to 672 but that did not fix the problem.

I have tried two different laptops - XP 32bit and Windows 7 64 bit , both via USB. I have also tried different combinations of timings and buffer lengths. The install seems to go fine except for the end result.

I read someone else had this problem in the above thread (sorry I can’t find it now) but no answer was given.

I am now thinking that it may have something to do with the USB/bootloader but I am reluctant to experiment without some guidance.

Can anyone help please?

Gary

I think you might have talked to Perry in our service department about this?
Odd behavior that I’ve not seen previously… nothing about the firmware update should affect saved presets or factory presets. If presets are still garbled after a Factory Restore then the factory preset data in the EEPROM (memory) is corrupted. Can you send an all presets sysex file successfully? if not then it’s likely a problem with MIDI data getting corrupted as you transfer it. If so then you’re sorted aside from the ability to do a factory restore; you’d have to send a sysex file instead (or in addition to factory restore if a full reset is what you’re trying to achieve).

When you say you “can’t program new patches” what do you mean exactly? if you rename and change settings on a patch and press ENTER/STORE button and confirm Yes you want to save a patch, does it not save? Definitely not seeing that problem here.

Hi Amos,
Yes, I did talk to Perry. He told me you thought it may be a corrupt EEPROM.

I’ll post my reply to him here,

“Thanks for that info Perry, it gives me a better understanding on how the LP works. I don’t think, however, I agree with the diagnosis, that is, that it is simply a corrupt EEPROM. Here are my thoughts:

I know the instruments history as I bought it new from a dealer and I have used “Restore Factory” before with no problems.

The problem surfaced immediately after the firmware update to v3.1.

I have tried to send the patch file you gave me to the LP via midiox but the LP would not take the sysex dump, so something is wrong there.

I then used the Editor/Librarian to send factory patches to the LP(The editor sends all the patches as individual smaller sysex dumps.). This seemed to work and the LP displayed the new patches. However when I go to use the instrument it acts flaky. If I scroll through the patches sometimes it hesitates and when I try to edit the patches the buttons either do not work or I have to hold them down for a while.

CaptainKeytar seems to have had similar problems here:

Anyway I would just like to let you know that I appreciate how difficult it can be to support different hardware and software combinations and I would rather go through this process than have a machine frozen in time without all the excellent improvements Amos and others are adding to the instrument.”



So at the moment I still have a broken LP.

What do you think of re-installing the USB fix and the bootloader? Or is it too late for that?

Also, can I try installing the v3.1 firmware via midi or must I use USB now?

Cheers, Gary
