Scott, when it comes to GM or other standards we are not there yet. I have purchased the East West Colossus 32 GB Library which is also GM compatible. Kontakt has made some updates so that you can use it to call up instruments utilizing program change numbers. I will likely now make some compromises and use Colossus for both my lead and auto accompaniment instruments. The quality of these instruments is not as good as the top of the line pianos, trumpets, etc. in libraries such as VSL, QLSO Gold/Platinum, etc.

Also as you know you can save midi files as projects in Sonar or Cubase which will call up the correct instruments and effects via VST or DXi, etc. This would be excellent for studio work but to slow for live performances.
