hi! i just received my copy of iLife i was longing for since i heard of its coming into life.... first program i tried was of course garage band. i once bought a Roland PC-300 USB-Keyboard to use it with emagic. this was pre-os-x time now i expected garageband to just work, so i connected the keyboard to the mac and started garageband made a new song and hit on my keyboard, but i heard nothing. so i tried it with the mouse and the key-board-window and it worked. it seems as if my usb-keyboard does not work with garageband?! the apple-system profiler shows on the first USB-Bus "Vendor-Specific" do i do something wrong, or have i missed something?
