Thank you, Andrew, but so far I have not been able to get SampleTank to work by putting different samples in the different channels either. They load, and I can press the virtual keyboard but there's no audio output at all. As for the PlugSound plugin, I will continue to play with it as time allows. For right now, the Coyote plugin is working properly but I see that as an interim solution as I don't want to buy still more plugins.
