Just got a Preenfm2. The only sound bank I can find online is the funky 2 bank, plus when I try load DX7 sysex files on the preenfm2 but they do not show up to load.I have created the correct file & loaded it onto my USB stick but preen isn't reading it. Can I create loads of files full of dx7 sysex files (tons online)& number them & access them. Please help. Could somebody break down how my files should be set up on my USB,? I've tried to follow the manual & online info but I'm too thick. Please help.
