I have a similar problem. I can get the soundfonts to work, but only when I take them out of their folders and place them on the desktop. I must also "attach” them every time I start the computer. If they aren’t on the desktop, my Home Studio won’t find them.
This morning, after reading this post I got the idea that I could maybe correct the problem. So I went to one of my songs and tried to fix it. This time I left the soundfonts in a folder within a folder in my “document” section in the computer. When I got done, the “banks” dropdown was empty. The computer was giving me a message that the “path does not exist” (to the soundfonts).
I tried it again with a New project and it works just fine. Home Studio XL finds the soundfonts with no trouble. But how do I get it to find soundfonts in an old project?
