Ugh, I've run into that one before. If it doesn't mess up existing sequences you can alter the GUIDs and patch numbers of the instruments before copying them to the new DLS instrument. That way there's no conflicts. Somehow, I still remember having to go back and manually edit a bunch of stuff :( Here's a lamer answer: I do remember when playing with it, the order in which you copy the instruments makes a difference in how scrambled things get. Try a few different orders. Wait, brain coming to life....Are you making these instruments outside of Producer? I seem to remember my issue was with trying to combine instruments I had converted from other formats in Awave. I think that's why there wasn't a great solution, there was some kind of conflict between the two programs. -Scott Morgan This message is "as is" and confers no rights whatsoever.

To do so I insert the dls files into a common project and create a new dls collection which will hold all the instruments. After I copy a dls instrument from the inserted collection then paste it into the new dls collection which has at least one other instrument in it, I find that the new copy of the instrument has several of its wave assignments scrambled, usually choosing the waves of one of the other instruments in the target collection. Is there a work around or patch for this problem aside from manually rebuilding each instrument from scratch? Jeff Gatlin Simutronics Corp.
