Where to Place Midi Driver for Casio LK-55 on iMac

I don't have that folder in my Home folder (there is a MIDI Configurations folder), but I do on the hard drive
Macintosh HD>Library>Audio>MIDI Drivers.
Do you not see that when you click on your hard drive in Finder?
(I also have 10.4.11).

PS - Casio is notoriously incompatible with Mac. I hope it works for you.

There is a difference between home folder/Library and Macintosh HD/Library?

Yes.

That's about as technical an answer as I can give.
I think their is a Home folder for each account on your Mac. (You may only have one account). The HD would be for every account.

things installed at the root level are accessible to all users. things installed in your home directory are only available to your account.

the root level is probably the better choice, but if you want it in your home directory, just create the required folder path (BTW, I do have Driver folders in both locations)

How do enable the plug in?

you don't enable it, it's not a plug-in, its a driver. it either works or it doesn't

I looked in GB SysPrefs audio input - it only shows built in line or mic or system setting.

MIDI ≠ Audio, so unless you plug an audio interface of some kind in to your Mac, that is all you will see.

0 midi input detected

if your keyboard is plugged in and turned on, and it still says 0 devices, then that is the wrong driver, i'm afraid.

as poflynn points out, sadly, Casio is not known or being very Mac friendly, but you might try their tech support, it's worth at least asking if they have a driver for your mac model and OS version.

Can't believe I typed "their" instead of "there."
