This may come as a double response if so I'm sorry. Anyway, thanks for answering Choppin. I have not tried using my Casio with my DAW. However I had it connected to the computer for use with the software which I use for storing/editing sounds for shows. I had been leaving the connection to the computer up even when I was not using the software. I wondered if that could have been playing a part in the problems. I disconnected the USB and I have been surprised/relieved that the issues seem to be gone. I am keeping my fingers crossed that it is a problem now solved.
