If the Retro AS-1 control panel switch 'Publish FreeMIDI Names' is unchecked, you will need to provide a FreeMIDI names document so that applications like Digital Performer can display the Retro AS-1 bank and program names correctly. The 'Retro AS-1 FreeMIDI Names' utility automatically generates this document and installs it in the proper location System Folder:FreeMIDI Folder:Default Names:BitHeadz.
If the control panel switch 'Publish FreeMIDI Names' is checked, you will not need to generate a names document. The names will be automatically generated every time the Retro AS-1 engine is used by FreeMIDI. If you notice that it takes a long time for Performer to start up, you might want to try unchecking the control panel switch and using the 'Retro AS-1 FreeMIDI Names' utility.
