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

Thanks Aaron i just took it up to my local music repair center the guy there has a emu rack to test the roms and says he thinks its a issue with the board he is supposed to call me later after checking it out. I highly doubt i wiped the rom chips i think i might have just knocked something loose when i opened it the unit has not been opened ever and the original owner used it live so i can imagine it might have been bumped around but it was in really good shape besides a few little scratches in the side. Lets all keep our fingers crossed for the fallen solider.

As far as testing stuff, make sure you're nice and grounded (you could wire yourself to the chassis). I'd check so see if all the internal ribbon cables are firmly connected, ensure the pins in the ROM slots aren't bent or touching (or have something in there), etc. You can clean the contacts on the ROM with a standard pink pencil eraser.

As far as the MIDI stuff, the MIDI test will fail if you don't loop a cable from in to out. Those diags were really not for the end user - they're more for manufacturing, so they aren't really user friendly. In any case, the MIDI test works by ensuring that data sent out the back comes back in the input unadulterated, thus requiring an external MIDI cable.

Subject: [xl7] Re: Hoping someone can help PLEASE no sound rom

Ok so i just got home from the music store and got a yamaha usb to 
midi adaptor and it works fine i tried it with another item but now 
the midi on the mp7 is not being recoginized so i cant even do the 
update with e-loader. It is receiving midi in messages but not midi 
out ( i think ) I tried the midi diag. and it says midi loop failed 
and the mp7 does not show up anywhere. I also tried to just it as a 
control surface and trigger sounds in battery but no luck there 
either. I even took out the rams and cleaned the chasis with contact 
cleaner carefully this morning them put them back and hoped it would 
work. Any other suggestions before i send this off?

which 
i 
have 
had 
in 
the 
machine 
and 
working 
perfectly 
would 
now 
will 
not 
show 
since 
i 
tried 
to 
install 
the

Its 
not 
even 
in 
there 
anymore 
and 
the

still 
will

up. 
It

the

everything

works 
it 
triggers 
midi 
, 
the 
lights 
all 
work 
, 
the 
ram 
test 
was 
fine 
, 
the 
fx 
is 
good 
the 
only 
thing 
wrong 
is 
the 
unit 
will 
not 
read 
roms. 
I 
dont 
know 
how 
this 
could 
of 
happened 
by 
just 
inserting 
then 
taking 
out 
the 
xlead. 
I 
want 
to 
try 
to 
get 
this 
figured 
out 
before 
i 
ship 
it 
off 
for 
a 
75 
benchfee 
just 
to 
look 
at. 
I 
iwsh 
i 
had 
another 
unit 
so 
i 
could 
check 
the 
roms 
but 
i 
dont 
even 
know 
anyone 
around 
here 
with 
a 
rack. 
The 
manual 
offers 
no 
info 
and 
i 
could 
not 
find 
anything 
on 
the 
web 
i 
have 
been 
digging 
for 
hours.
