Keyboard as Midi input

Hi there,

I want to use my oldschool keyboard (Yamaha PSR 740) as a MIDI device for programs like Absynth 4, Akoustik Piano and Garageband. I got a Xmidi 1x1 cable (MIDI to USB) and when I connect it to my MacBook, Garageband tells me it has found a new MIDI device. But when i play some keys nothin happens. Is it a software issue? Where do I need to change something?
Oh and an additional question: In Absynth 4 on Windows there was a record button, where is it in de Macversion?
Thanks alot for any help

PS. I'm a novice in using mac

Were you able to get GarageBand to hear your keyboard? I'm stuck with the same problem.

Try plugging the midi plug that is labelled "Out" into the "In" socket of your keyboard, and the "In" plug into the "Out" socket.

Seriously - this isn't a prank, it's what made mine finally work.

Another tip: when you're testing this, don't bother playing back a track you've saved inside the digital piano - the Mac still doesn't "hear" those for some reason (don't know why yet), but it will hear fresh notes you press on the keyboard.
