Step 1) Install Drivers from the keyboard on your computer (FYI dont open reason until installation is finished.
Step 2) Restart your computer
Step 3) Turn On the Keyboard.
Step 4) Open Reason!!!!
Step 5) Go to edit-Preferences-midi- go to auto find or somthing of that sort.
Step 6) hit a key so that reason can detect the keyboard.
Step 7) Make Sure the octive is down at 0 (do note that some patchs wont play in certain octives.
Step 8) If the set up doesnt work that way go to Edit-Preferences and select the bus and set the keyboard to bus A, B, C, D or any of them really.
Step 9) Are you selecting the record button the squencer to select what device is going to be used with the midi??
Step 10) If all else fails you tried hard and thats all that matters....Just Kidding throw that keyboard out the window or mail it to me =P
GOOD LUCK!
