I have two Midi devices connected to Reason, they both work fine untill i try to record from both midi devices at once, when i hit record midi device 1 playes both sounds, How do i Enable both tracks to record from seprate Midi devices?

Highlight the two devices by holding down the shift key. Now, go to edit and select combine. Make sure that the combinator is selected at the bottom left. You can adjust the mixer volume to get the right sound.
