[sdiy] JP6 doesn't write presets. CR2032 over CR1/3N - OK?

[Doug Terrebonne]

Acually the correct procedure in this specific case is to install the Europa upgrade which stores patches in flash memory and supports sysex dumps. :)

Without Europa you can deal with loading the patches after a batt swap from tape/wave file with various degrees of succces. The JP-6 without Europa can also lock up and exhibit other weird behaviour if invalid corrupt patch data is in memory...
