Emu XL-7 & MP-7 User's Group

Hi all... my XL is beginning to develop a habit that makes me worry a 
bit...

I'll be playing out, editing a pattern or a song, and as I push 
various buttons, my display begins to fritz out... It begins to 
slowly display random characters... they don't look like random parts 
of the LCD lighting up, but maybe some sort of foreign alphabet?!

At first, I can clear it up by pushing the PATTERN or SONG button... 
but eventually it takes over so that my LCD is just full of these 
characters and won't change at all.  I have to power it down 
completely.

But THEN... the next time I power it up, it freezes... all the LEDs 
light, the LCD lights up but displays nothing, and the unit is 
unresponsive.  Sometimes if I boot into test mode or credits mode, it 
will kick back in, but I find most of the time I have to disconnect 
it from the mains and let it sit for a while before it will boot 
again!  It doesn't seem to affect my user data.

I can't really pin down a single cause or pattern, but I know that it 
normally begins to happen if I'm pressing buttons rapidly, or if I 
work on the machine for a long period of time (maybe 3-4 hours)  Once 
the strange characters start to appear, there's nothing I can do... a 
crash is inevitable...

And to top it off... I think it's getting more frequent, and crashing 
faster with each occurrence! That could just be me getting gear-
paranoid though...

Any thoughts on this one, group?  I'm getting nervous about even 
turning my XL on... I'm afraid I'm doing some sort of damage!

Thanks

SC

Does this only happen while you're playing out?  I had very some weird 
issues last week during my live set too:

- 16 measure patterns looped for 32 measures, even though 17-32 were 
blank.
- Patterns wouldn't switch even though they were queued correctly, the 
current pattern would play indefinitely.
- Pressing Edit+Track Mute to select a new track would cause the XL-7 to 
play random sounds not from the Preset assigned to that channel.
- Lots of other stuff that killed the set.

Never seen any of these before, and haven't seen them since no matter what 
I try.  After some talks with Emu, we are both inclined to agree it was 
most likely issues with the mains power at the venue, it was probably too 
low.  I know I'm buying one of those cheap USB power supplies ($40) from 
Office Depot to remedy the situation in the future, might want to look 
into that as well.

I had this same problem a few weeks ago after
installing a SIMM.  I would check and make sure that
all cables and screws are in tight.  A loose cable
will definately cause the symptom where all the lights
are lit and nothing appears on the LCD.  If that does
not fix it try reseating all of the SIMMS that you
have installed.  That is what fixed my problem when I
had it.

electronic device you DO NOT touch the power supply. The good news is the
xx-7's have power supply covers, but many products do not. Even after being
turned off, many power supplies will carry their charge. DANGER, you will
be shocked.

Right on, I will check this out when I get home... It makes sense, 
because I just recently had the unit shipped to me... maybe there are 
just some loose connections or chips that need to be re-seated.

Thanks, I'll let you know how it turns out...

I agree on the power issue. I've encountered that before in many 
instances. It usually results from too many things pluged into the 
same circuit. Usually the synth has enough power to boot part way and 
that's about it. Usually when I play out I bring extension cords and 
power strips. That way I can find my own recepticles if needed.
