These are various abuttons for use with Opus. To use these uncompress each lha file, and you will see a configopus.clip. You have to do each button separately, because each .lha file decompresses to a file with the same name, configopus.clip. Copy the .clip file to your t: directory (Most people have this in Ram:). Now go into Opus and choose the small C button to enter the configure program. Select Buttons in the Configure protram. Choose a blank button. Now hold down the right mouse button, and choose paste from the menu. Paste the .clip file, and you will have a new button. The file comments on the .lha files will explain what the buttons do.
