Tom, nice to see you are using some very high quality synths and instruments. I believe GigaStudio 2.5 and 3.0 are able to accept patch changes from your keyboards. Due to copy protection, it is not possible to convert encrypted Kontakt files to GigaStudio. In the old days you could purchase almost any file format and convert it to the one you were using. The conversions were not perfect but good enough to get you started.
