Thanks Herbert, David...but this machine runs entirely ASIO with an Audiophile 2496 and all the right inputs, drivers, boxes are ticked. What irriates me is that midiyoke was working then started the slowdown running COmposer. I have no issues at all in Music Creator/SOnar although they're entirely VST based. I have no issues at all with Garritan Studio. So I'm scratching my head...I wonder if the midimapper has inserted iself...
