Thanks for your reply.
I know how to transfer the data from Logic to my D-50 once I have it in the program. The problem is that I can't import the patch data into Logic. If I choose 'Import' nothing comes up. If I drag the patch icons into Logic nothing happens either. I cannot tell from the looks of the downloaded patch data icons which format they're in. I have also tried to rename them by adding '.mid' to the end of the file name. What to do, what to do?
Thanks for helping me folks.
