Members Tony Scharf Posted June 20, 2006 Members Share Posted June 20, 2006 Ok, so I am the last guy still using an EMU hardware sampler. shoot me. Anyway, I am in the process of integrating it into my studio, and added an adaptec SCSI card to my PC so that I could shuffle samples to and fro. scsi wise, everything works. the PC sees the EMU and the EMU pretends the PC isnt there, and the Jazz drive in the middle works fine for either. the *problem* is that whenever the SCSI cable is connected to the pc, I get an unpleasant digital noise burst about every 2 seconds on EVERY instrument in my rig. Its damn annoying. The whole studio is properly grounded, and all the gear is on the same circuit, so I dont think its ground loops. Has anyone else experienced this (think back..maybe..10 years or so) and have a solution, or possible solution? these old boxes didnt read PC disks with .wav files, so if I cant get SCSI in and out/its going to require a dramatic shift in how I planned to work with the unit. Thanks.Tony Link to comment Share on other sites More sharing options...
Members Veneficum Posted June 20, 2006 Members Share Posted June 20, 2006 I know they make a SCSI -> USB converter. I have seen people recommending them to old Triton Classic/Studio users on the tritonhaven.com forum. Link to comment Share on other sites More sharing options...
Members packrat Posted June 20, 2006 Members Share Posted June 20, 2006 You might put this on the emus on acid forum. QUite a few active threads on SCSI use there. B> Link to comment Share on other sites More sharing options...
Members Tony Scharf Posted June 20, 2006 Author Members Share Posted June 20, 2006 Yeah, I was thinking about that. Ive got so many USB thingies hanging out of my PC its rediculous. Someone needs to make me a rack mount 32 port hub to handle all this crap... Any idea who makes that? Link to comment Share on other sites More sharing options...
Members Umbra Posted June 20, 2006 Members Share Posted June 20, 2006 Check for resource sharing on your PC such as your sound card and something else like the new SCSI card. My delta 1010 was sharing an IRQ with one of my usb chains which caused constant clicks and pops. I solved it by disabling my serial ports in the bios and thus freeing up more IRQ's. No more sharing of IRQ on the delta meant no more clicks and pops. Link to comment Share on other sites More sharing options...

No more sharing of IRQ on the delta meant no more clicks and pops. I tried that. Its still there. I actually think it may be because the sound card is next to the SCSI card. Unfortunatly, I cant move them, as ive run out of case space. I am thinkin the USB option is probably the best one. Link to comment Share on other sites More sharing options...

Doubt it, sounds more like there is a conflict or the SCSI card is taking over the PCI bus every few seconds and interupting the sound card. How is your bus mastering setup? Unfortunatly, I cant move them, as ive run out of case space. You only have two PCI slots? Just exchange the scsi card with something farther away. There is a reason SCSI is going away.....

Members Veneficum Posted June 20, 2006 Members Share Posted June 20, 2006 The tritonhaven.com forum is down right now but if you just go to pricewatch.com you should find something that works for you... http://castle.pricewatch.com/s/search.asp?s=scsi+to+usb If you scroll down a bit there are a few things there.

Members mikesr Posted June 20, 2006 Members Share Posted June 20, 2006 Do you have EOS link running in the background? Link to comment Share on other sites More sharing options...
Members Tony Scharf Posted June 20, 2006 Author Members Share Posted June 20, 2006 Nope. I find eoslink to be pretty much pointless if the rack is within arms reach (which it is) Link to comment Share on other sites More sharing options...
Members mikesr Posted June 20, 2006 Members Share Posted June 20, 2006 Agreed, I use it when I'm not close to the rack but it does make noise when it's up. I'm not sure that a usb to SCSI adapter would give you different results. I would ditch the Jazz drive for now and see if you get the same problem with the PC and EMU connected directly. You might consider installing a harddrive in the EMU and just spend some time creating banks and storing them on the harddrive. I know it might cut into the workflow however. You're not the last one and as was said, EMUs on acid might be of some help. Link to comment Share on other sites More sharing options...
Members Tony Scharf Posted June 20, 2006 Author Members Share Posted June 20, 2006 I took both the Jaz and zip drives out and connected them directly and got the same noise, though it was quieter (the jazz drive is obviously aggravating it). I do have a drive installed in the EMU, but its only 600MB, and already full of stuff. Ive considered putting the Jazz drive into the ESI4000 above it in the rack, and then putting them both on their own chain...but ive been too lazy. If only it read .wav...this would all be moot.

Members XorAxAx Posted June 21, 2006 Members Share Posted June 21, 2006 Are you sure the SCSI card is not sharing an IRQ or other resource with another component? If it's sharing an IRQ, that means every time the SCSI card tells your computer to process a piece of information, your computer has to notify two separate drivers -- one for each device sharing the IRQ. The computer simply doesn't know which driver to run, so it runs both. And there are a lot of drivers (especially for older hardware) that aren't written to support IRQ sharing, or for that matter, sharing an IRQ with an audio device that needs certain response times.

Members Tony Scharf Posted June 21, 2006 Author Members Share Posted June 21, 2006 I checked it all out, and I dont have any IRQ sharing going on that should cause any issues. There actually ended up being a simple solution to this: hook the E64 directly to the PC SCSI card, and put the Jaz drive between the E64 and the ESI4000. It took some cable juggling, band a little rearrangment of my rack, but it all works now.. I dont know if its a bad cable in there or what, but the noise is definitely gone now - though i still here some bleed through the E64's outputs while actually doing a disk opperation. I can deal with that. Tony Link to comment Share on other sites More sharing options...
