Well, if you've been to Vlad's site at:
http://www.ece.mcgill.ca/~vromas/vdmsound/
Look under "What's new", you'll see:
20-Feb-02 / First beta of the long-awaited VDMSound GUI was released. The GUI, code-named Launchpad, can be downloaded from http://vdmsound.sourceforge.net/files/. Read the README file carefully before installing and using. Also, the GUI is an ADD-ON to VDMSound 2.0.4, in other words you must have both VDMSound 2.0.4 and the beta GUI installed in order to use the GUI.
Also at that file location, you'll find his GUI update VDMSLaunchPad.v1.0.0.7.zip, and VDMSound.2.0.4.update1.zip (both from May), and DiskWriter.v1.0.4.3.zip (which, IIRC, adds the ability to dump AdLib ouput into a MIDI file. From the end of June).
