I have successfully managed to do a USB to SCSI sample dump from my Intel C2D Mac Mini to my e6400 (upgraded classic). My goal was to only have 1 small computer in my studio to reduce noise and heat, save space, and basically force me to utilize the hardware as much as possible. I do still use my computer quite a bit and in conjunction with a SCSI CF Card reader that I added to my e6400 as wellI thought it would be perfect to make this combo work for quick transfers and archive purposes, to have the ability to transfer sounds between my e6400 and Mac. For a while I kept a Windows PC in my studio as well but, I really only used it for EMXP (which I can also use my Mac Mini for now) and Soundforge for dumping sounds to my e6400. Now, this is no longer required.
What you need:
-a Mac PPC OR Intel running OS X (I am using a Early 2009 Mac Mini 2.26 core 2 duo with 8gb's of RAM)
-for PPC OS 10.4 or lower OS X (I am actually running OS 10.6.8 on an Intel core 2 duo but, I managed to locate an OS 10.4.10 virtual machine online (shhh, don't tell Apple!). What I have determined is that OS 10.4 is the last OS that fully supported SCSI. In all my tests with SCSI+ 10.5 and higher have failed with the EMU's.). If you know of a way to get the newest OS X to support SCSI, please reply to this post.
-Castlewood USB to SCSI adapter (this is key as it is the only known USB to SCSI adapter to work with the EOS Emu's and OS X, as far as I know (and they are fairly rare but still found on eBay from time to time))
-BIAS Peak 5.2 or lower (must be OS X compatible of course)
1. Connect the Castlewood SCSI to USB adapter to your Mac and Emu EOS sampler.
2. Start up your sampler
3. Boot the computer (In my case, what I have done is run OS 10.4.10 in a Virtual Machine so I start it up and connect the Castlewood to that system)
4. Start up Peak
5. Load a 16bit 44Khz wav file (stereo or mono, preferably under 30 seconds long) and then highlight it by using the select all function
6. Go to the sampler menu and select the Emu Sampler option, then press transfer. (if the sampler menu is not available, then you may need to check your SCSI settings on the Emu. I believe the termination setting must be set to "on")
7. Give it a few seconds to transfer and you should then be able to go to the edit sample page and audition your sample.
As I mentioned, the Castlewood is the only unit I have ever witnessed working with the Emu from OS X. There used to be another user on here named Drayon who told me he had an adapted SCSI to USB working with an old Pizmo G3 but, I cannot verify that.
I will try to post a video of this working for everyone soon.
