MidiSportLoader for Mac OS X 10.5

This package allows you to use some M-Audio USB MIDI and Audio interfaces with Mac OS X 10.5

NOTICE: MidiSportLoader will not be further developed. M-Audio has already updated drivers for MidiSport, KeyStation, Oxygen 8, Radium and MobilePre devices, I suppose others will follow soon. I neither have the hardware nor the resources to add support for any other devices. Thanks to everyone who supported my development. If you have any other question regarding MidiSportLoader, feel free to contact me at the address below.


M-Audio has not provided drivers for Leopard yet, and the existing drivers for Tiger won't work. I don't want to wait some weeks for drivers for my MidiSport UNO, so after some research I found how to get it working.
The code is based on the usb-midi-fw package. It requires copyrighted firmware that I cannot distribute, it will be downloaded automatically when you install or build MidiSportLoader.
If you have any other question, send it to .

MidiSportLoader supports the following USB devices: * devices not tested but should work, e-mail me with your results if you have one


Installation Instructions

You must first install the M-Audio driver, which includes the MIDI plugin for the MIDI system to recognize the device once the firmware is loaded.
You must have an internet connection for the installer to download the firmware from SourceForge.
If the preinstall script fails, you can try again, or download midisport-firmware-1.2 and madfuload-1.2 yourself and put the .tar.gz files in the /tmp directory.

Uninstallation Instructions

To uninstall, double click the Uninstall.command script you'll find in /Library/StartupItems/MidiSportLoader/, it should run in Terminal
You need to be logged in an administrator account, and you will be asked for your password.
Alternatively, you can delete the MidiSportLoader folder that's in /Library/StartupItems with Finder, and restart.

Build Instructions

If you'd rather build from source, it's quite easy too: When building with XCode, the firmware will be downloaded automatically from SourceForge, and after building the driver, a convenient Installer package will be generated.
The generated package includes the firmware, unlike the one you can download here, so it can be installed on machines with no internet connection, but it cannot be legally distributed.
If the download fails (you will see it in the build results window), you can download it yourself and put it in the source folder, the build script will find it and decompress it.
