Sound Edge Setup
ABOUT THE DRIVER AND MIDI MAPPER
In order for Windows to work with MIDI, a driver and MIDI mapper are required. The Yamaha
Sound Edge software installation procedure automatically places the YAMAHA OPL4 Driver in
the Control Panel and the YAMAHA OPL4 MIDI map into the MIDI Mapper.
When you click to open the driver in the Windows Main group, you can see three different
drivers: OPTi External MIDI Driver, YAMAHA Audio Device Driver and YAMAHA OPL4 Driver.

If you removed a previous sound card before installing the Sound Edge, delete any accompanying driver
programs.
