You're brilliant! it works like a charm now! Boy I would have been struggling with this for weeks. Thanks a lot!

btw; to compare the changes from using TResourceStreem to this:
With TResourceStreem my exe containing a 24kb MIDI was 74kb compressed with UPX. When using this, the exe is 65 UNCOMPRESSED and 21kb (!!) compressed with a 24kb MIDI. This file also containes the playback engine for my demosystem, AND a datafile for the intro
