You will be prompted for a disk drive from which to read
the Windows 3.1 drivers. Insert the proper Windows disk
into your floppy disk drive, and, if necessary, enter the disk
drive specification in the prompt box. Click on OK.
9.
When the “Add Unlisted or Updated Driver” Window pops
up, select the “Roland MPU-401” and click on OK.
10. The Roland MPU-401 driver setup dialog box will then
appear. It will allow you to set up the driver to match the
interrupt/IRQ and address settings on your MM-401 card.
Some systems use MPU-401 address/port settings other
than those available in the dialog box. You must then
change this manually by editing the “SYSTEM.INI” file in
your Windows root directory, and changing the address/
port listed under the [MPU401,DRV] for your hardware.
Warning:
Be careful when doing this. An incorrect setting
may result in your computer crashing or locking up. If there
is any question about how to make these changes, please
consult your computer’s user’s guide or manufacturer
directly.
11. Once you’ve selected the interrupt/IRQ and address/port,
click on OK.
12. In order for Windows to install the new driver completely,
you will be required to exit and restart Windows.
13. After restarting Windows, run your MIDI application(s). You
will need to set up each MIDI application in order to use the
MM-401 as the selected interface. From within the applica-
tion(s), select the MPU-401 as the current device. (The selec-
tion procedure will depend on the application.)
