Gordon, I have a M audio delta 1010 lt, a M audio pro 88, a AMD 3200, a second sound card for Jaws, Sonar and Sibelius that I do not use at the same time, And that is pretty much it. Do you think I should give you more detailed information about my configuration, or is this good enough?

When I load a sound in to Sonar and play it on my m audio keyboard the sound gets stuck and sustains for ever. Sometimes pressing the space bar helps to stop it but sometimes I have to close Sonar and restart it. What do you think the problem might be? And how can I resolve it?
