Trouble Shooting about Computer
My computer hangs up when I open a MIDI file
This problem can occur if the USB waveform of your computer does not sufficiently meet the standards.
In this case, the problem may be solved if you connect the MMP-2 via a USB hub (USB hub containing a
power supply).
Macintosh users
An error dialog box is displayed
◆Is the MMP-2 driver installed?
An error dialog box will be displayed if the MMP-2 is connected to your computer before the MMP-2
driver is installed.
If the display indicates “The software needed to use the USB device “Unknown Device” cannot be
found. Please refer to the device documentation to install the necessary software”, click “OK.”
If the display indicates “Software needed for the USB device “Unnamed Device” is not available.
Would you like to look for the software on the Internet?”, click “Cancel.”
After closing the dialog box, follow the procedure for “Macintosh / OMS” (p. 35) or “Macintosh /
FreeMIDI” (p. 38) to install the MMP-2 driver.
