this one must have been dealt with before:

i just just got back to my ex800 after a long time.
it is still unmodded, and the battery clip i'd installed
instead of the original soldered battery had come undone,
so no patches, and the usual slow-rise noise with delayed
vcf LFO patch(...). but my buttons are fer sh∗t: 5 almost
doesn't work at all, 3 is dodgy...well, they're all in a
pretty rough state, makes progging a nightmare.

so, what is the info on this? must i remove that board and
somehow open up the switches and clean them? i'd like to sort
this out before i attack the mod.

2nd question/issue is something i have wondered about for a
long time: the difference between the pulse wave and the saw:
on my 800, the 'saw' sounds almost the same ('square-ish'),
just louder. i wouldn't say either is distinctively square
or saw...kinda in the square department more, and i'm not
really hearing a distinctive 'saw/ramp'. is this normal?

number 3 is: could somehow explain, or do a sketch for me,
of wha exactly the envelope terms 'slope' and 'breakpoint'
mean?(ok, so i was mucking around with it with the VCF EG
inverted, and that didn't help clarify much- again, the default
noise patch)...pathetic, really, when i've had this thing for???
well over 15 years.
