I have another Lenovo laptop which I use exclusively as my DAW.

The main program that I run is Band in a Box under WINE.

When I switch on the computer, choose Band in a Box and start to play one of the tunes, I get a message box labelled "Unable to use MIDI output driver" with the contents of the box saying "TiMidity Output driver is installed properly but is currently in use by another program."

I then get the option to choose another output channel and the program works.

How do I find out which other program is using the driver so that I can stop it and prevent this problem?
