Garageband recognizes midi but won't play

I started out with the interface cable marked OUT to the OUT port on my keyboard and IN to IN. I thought that made sense, but after your suggestion I switched them to Out-->IN and IN-->OUT, but still nothing.

Hey, I FINALLY got it to work. I took your suggestion and put In to Out and Out to In, and got nothing, but then as a final last resort I reset my QS7 to factory settings and it worked! Woohoo! This is an old keyboard I've had for years and obviously I had screwed around with the programming to the point that the MIDI settings were all messed up. Resetting the keyboards did the trick. Thanks for your help and patience!

I am recording on a software track (green - piano). It doesn't register any notes when I record. I don't get a little blue dot in the LDC window when I strike a key on the keyboard.
