Thanks Audrey:
Sorry for the late reply...
The seq files are in PR804 format, which loads and plays fine using the floppy. The PR804 doesn't have a SD Card Slot.
I will load the same exact files using the laptop to PR, but get a tranfer error only when it tries to load the Seq file.
I also downloaded technics format files from the PR to the laptop and it works, even the seq files saves. I will then take that exact setup and try to upload it to the PR, using the laptop and as usual get the tranfer error. I also copied the setup that was transfered from the PR to the laptop on a floppy which loaded on the PR with no problems.
The only other thing I can do is find another USB cable and see if that makes a difference.
