Thanks for your responses.

Mario - I'm using Win 7, so the driver issue shouldn't affect me.

Bob - Yes, my input & output drivers are set to UM-1, which is my Edirol interface between the computer, Ketron and PC.

I've also ensured that the "Use VSTi/DXi Synth" box is not checked.

Thank for offering possible solutions.


Cheers,
Keith
