emusonacid! legacy

hi,

just bought an e-mu e5000 ultra the other day off ebay and i've been having one or two problems with it...

when i create a new preset and try to save it in any new folder i specifically create, the e5000 throws "scsi driver error!" onto the screen.

after this, i can't access the hd and have to reboot if i want to access it.

the puzzling thing is that it works perfectly when loading stuff from the hd **AND**, really confusingly, it lets me save new presets in the empty banks of folders that already exist on the hd.

the info on my hd says that the drive is 39200 mb and i'm using 28928 mb (-33% the - sign is there on the screen, i don't know if it's supposed to be).

it says folders 23/112 20% and banks 904/11200 8%

i'm running eos 4.02 and all my scsi peripherals are unplugged and the scsi id under master/setup/scsi is 1, with scsi termination on, disk button goes to: last and avoid host on id: none

can anyone help?

I am having similar problems to the above (with my E6400 Ultra).

Is there anyone out there that has had this problem and have fixed it?


Thanks,

This sounds like a termination issue. If the drive is on the internal SCSI bus, try different termination settings. It should be

Drive is terminated
Emu termination on (but no hard in trying different settings - you will know when its right :)

If you bought off e-bay, then its possible that the unit was connected to a PC over SCSI, so in that case termination would be on both ends - the drive (you will have to open the Emu and inspect the drive settings), and the PC.

Also make sure the EMU SCSI ID is not the same as the drive ID. Emu's behave strangely when there are conflicting ID's - you'll see for example one drive appear as 7 units or non at all.

I'm having the same problem. I changed the drive settings around and now it sees the internal drive. I put a new one in there. I sampled and few sounds and it seamed to work fine. Then I sampled one more sound and now it says unknown file type. How can this be since I just made the samples using the hardware sampler. I try to load the bank and it says unknown file type. Please someone help. Thanks for your time.

take care,

What you are seeing seems like termination. is the external scsi bus being used to connect to anything else ? PC ? CDROM ? If so, termination on the drive must be on, ultra internal termination must be off (software controlled switch), and external endpoint e.g. PC SCSI controller must have termination.

I find that the Ultras are VERY sensitive to poor termination or poor cables (usually external cables) so you have to try all manner of combinations, and loading and saving an entire very large bank several times to be sure.

So, write down the combinations as you try various termination settings, but each end of the scsi chain must be terminated properly. The reason is that SCSI needs the line balanced so you don't get signal reflections from each end or device - with partially "ok" termination short signal bursts may come out ok, but sustained data transfers from one end or the other of the line can become corrupted - probably what you are seeing.

Lastly, it could be the drive itself or the current draw being incompatible with the EMU. I've moved to low power laptop drives on the IDE bus and they work fine. Pretty sure the ACard SCSI-IDE adapter would also alow you to do this nicely for scsi only samplers.

Good luck!
