Hi,
First check to see if the problem is on one particular channel (listen to
the individual outs with ROM and RAM sounds). If ROM and RAM sounds always
cause problems on a channel then its a sample replay problem in the analog
circuit for that channel.

If all the RAM sounds are always okay and some of the ROM sounds are
distorted/high pitched, particularly if mid way through - then suspect the
factory EPROM's. EPROM chips do eventually die (yes including the EII and
SP-12 boot EPROM's....). You can easily get a new set of EPROM's burnt by a
service centre - I have the binaries. Some E1 users have already encountered
boot ROM death, and EII users will see this happening over the next 5 - 10
years. Lucky we have all the EPROM binaries available to recreate them!

A service centre would also swap the sample EPROM's about to see if the
problem is the chip or the replay electronics. Please don't attempt repairs
without thr right equipment/training and the power OFF.

Rather Off Topic...if any one is interested in the factory SP-12 samples in
LM-4 format....let me know!

Regards
Rob

i have tried it again today...

looks like these noisy sounds have now become a permanent error on
my sp12. when i switched it on again today, there were the same
things going wrong as yesterday. i can say more about the problem
now, because i have tested a few things:

- tried to put user sounds on the "failing" drum-buttons, that works
fine. i also have a list of all the factory-drums making the
described problems.

snare1 (completely)
snare2 (completely)
ride1  (completely)
ride2  (completely)
crash  (just a slight bit of the end)

i have recorded the failure and will send you an email, with an mp3
attached. you can answer me via email if you want - or in the forum,
depending on your oppinion wether this could be of any interest for
other users...

thanx in advance and please don\ufffdt destroy all my hopes of me,
eventually haveing all my emu\ufffds working 100% - ok :-(
