Hi Noel

Thanks for your answer with clear suggestions for setup.

About the Roland sound interface, I have same drop outs with Roland on another pc running windows 7, so this could also be an indicator.

Except using VST/DXI Synth my setup was like presented on the image.

At the moment my driver latency is set to 488 ms in a previous attempt to solve the problem.

Last night I also chose “Microsoft Sound Mapper” as input/output driver (from another window) instead of Roland VS-20, but haven’t yet done a good test with that.

I will test the setup with "VST/DXI Synth" in the evening and come back with the results. I do not use keyboard, synth og any plugins. Just play back with real tracks.

Best regards

Henrik
