After download and preparation, you can install the driver:
- Turn off the EMU device
- Run the install script (e.g. double click it) and follow the instructions.
If you like you can also copy the control panel into your applications directory. You also have to copy the Skins folder along with the app.
NOTE: After the install, it takes OSX up to a few minutes to incorporate the driver into the kernel.
- Install the driver as above
- Use the EMU control panel to select the sample rate you want
- Select the EMU input in your favourite tool (e.g., Audacity)
- Make your recording
This is the procedure to completely remove the driver.
WARNING. Be very careful with the rm -rf
, if you give it the wrong arguments you may remove essential system files.
- Turn off the EMU.
sudo rm -rf /System/Library/Extensions/EMUUSBAudio.kext
(you need admin password).sudo rm -rf /Library/Audio/MIDI\ Drivers/EMUMIDIDriver.plugin
(you need admin password).- delete the control panel (if you installed it).
Download and install the original EMU driver provided by E-MU. Notice that this driver is not working on modern OSX.
The notes here are from users, I can not verify these myself.
The serial port has to be disabled in the bios. If enabled, the system detects wrong IRQ directions, the driver entries in conflict, which results in system malfunction when you power on your audio interface. (#134)
