John,
I had the exact same problem with my OB-Xa. Problem is that all the files that I found floating around the Internet on various sites for the OB-Xa patches were CRAP. There were problems with the wav file not being loud enough and when you boosted the gain in Windows Media player, it would distort, one file did not enough leader tone at the beginning and in another, there is a gap in the file a few seconds in, causing the transfer to fail.
NONE of these worked for me, so I ended up taking the best quality one I could find and went to work editing it in Audacity, cleaning it up, adding leader tone, normalizing it and adding gain.
Attached is the edited wav file. Worked for me on the first try, after about a week of pulling my hair out trying to load up what I found on the Internet.
You may need to adjust the volume in Windows Media Player, or what ever player you are using on your PC to make sure it is loud enough for the OB-Xa to "hear" it.
I used an iPod audio cable (1/8") and put a 1/8" mono adapter on the end plugged into the OB-Xa, since the iPod cable was stereo. It would probably work fine without the adapter, but just letting you know what worked for me.
Good luck,
Tim

I originally posted this question to this group. I received the factory presets in a digital file and was told you could load these presets into the Oberheim via the output line of a computer. My tech tried this and no luck. I then received some advise that you need to boost this signal with an amp or preamp to get it to the right level to dump into the Oberhei. I've told this advise to my tech and he's tried to boost the computer's signal with an amp or a preamp but still the sounds from the computer file won't load. Apparently the problem's not with the Oberheim b/c he was able to dump some patches from another synth into it just fine. Any suggestions why this isn't working?

I've found that I need to give my computer's audio output an external boost of +6db or so in order to get a DMX to accept sequence dumps played back as wav files. This is with the computer volume levels at maximum. ; I think the cassette interfaces on the Xa and DMX are basically identical, so this may work for you. A mixing board, clean guitar booster or some other non-distorting amplifier can be used.

Hello: I received a file from someone from this forum that was to contain the factory presents for the OBXA. My synth tech tried to load these into my obxa using the headphone line from his computer and said he had some signal/amplitude problems and couldn't load these into the OBXA. If anyone out these has loaded presets back into their OBXA (or OB-8 for that matter) using a computer compared to a tape cassette player, would you please kindly give me any advise on how to make sure the voices load into the Oberheim? Thanks in advance for any help!
