A Windows 95 program to create an Instrument Definition File (IDF). This is essentially Win95's version of the Patch and Drum Note remapping of Win3.1's MIDI Manager. An IDF allows you to remap the General MIDI Patch set and Drum Note assignments for a MIDI sound source that is not GM compliant. In this way, software that is designed to select patches and play drums upon a GM sound source will play the proper instrumentation and drum sounds upon a non-GM unit (ie, via the IDF you create for that unit). This is a zip archive, and you should use a utility such as WinZip to unzip it.
