loaded the Roland MPU-401 driver. This can be done by opening
the *Control Panel* icon in the *Main* Group and clicking on the
*Drivers* icon. For further information on setting up drivers
under Windows, see the *Windows* section.
If you are using a DOS sequencer that uses drivers, your program
will include MPU-401 compatible drivers. Make sure the MPU-
401 driver is properly installed. Generally, the MPU-401 driver is
installed as the default driver. If you have any questions about
which driver to use or how to install the driver, call the manu-
facturer of your software and ask them how to install an MPU
compatible driver. This topic may also be covered in your appli-
cations instruction manual.
Interrupt/IRQ and Address Selection
It is vital to make sure the “interrupt/IRQ” and “address” set-
tings are correctly set on the card. The default settings for the
MM-401 (and all MPU-401 compatible cards) are *address 330*
and *interrupt/IRQ 2*. If another adaptor card in your system
already uses these settings, your MM-401 may not work proper-
ly.
The MM-401 has eight dip-switches which allow the
interrupt/IRQ and addresses to be selected. The settings for
these switches have to be set so they don’t conflict with any other
cards in your computer. If you install your MM-401 and it does
not work correctly, you can use the installation program includ-
ed on the diskette to determine which interrupt/IRQ and
addresses are free. You may then select one of these settings for
your interrupt/IRQ and also your address.
