K5synth

Hi, new member here. I just got my K5 and I have a few 
questions about it I'd like to ask. First, mine has the v1.0 OS and 
I was wondering if anyone knew in detail what the v1.1/1.2 
EPROM upgrades specifically fix. I'm gonna upgrade to 1.2 
anyway, but I was just curious. Second, has anyone with the 1.0 
OS run into what I would describe as random re-triggering of the 
voices? What happens is that every once in a while when I'm 
playing, if I strike a key the K5 will play the note, but right away re-
trigger the note for a split-second, then trigger it again like 
normal. It sounds like a short "blip" or glitch usually, but 
sometimes it'll have some release to it -- kinda like when you 
switch patches while holding a sustained note and you can hear 
the settings reset to the new patch. Sorry if this makes no sense, 
but it's a bit tricky to explain without you hearing it. Anyway, I'd say 
it's not a dirty keyboard 'cause it's really random as to what keys 
it will happen with and there doesn't seem to be any repeat 
offenders that stand out like you would expect. Also, it happens 
fairly infrequently, but enough to cause some concern that 
something isn't right -- maybe once every 100-150 notes played, 
sometimes sooner. I haven't had the time yet to hook it up via 
MIDI to see if it will happen when controlling another board, or 
when being controlled, but personally I think it's a glitch or bug in 
the 1.0 OS since I read somewhere that newer versions fixed 
"clicks" or something of that nature. Has anyone here had any 
similar experiences, and if so, what was the cause? Sorry for the 
long post, thanks for your help! :)
