NOTE: This should only happen with drivers version 1.3 and above. The
      interrupt was disabled because many customers weren't using the TBS-2000
      to record MIDI from an external source. The interrupt is used only as a 
      clock for recording MIDI in, so it's not required if you aren't
      recording.
-----------------------------------------------------------------------------

To enable the MIDI In functionality follow these steps:

- Open the Dev. Manager, and double-click on the MPU-401 entry. Click on 
  'Resources' and remove the check from "Use Automatic Settings" checkbox.

- Change the Basic configuration to 0001. The Resource Settings window will
  now show an Input/Output Range, and an Interrupt Request. Make sure nothing 
  is conflicting before you continue.

- Close the device manager, and shut the computer all the way down (Start
  Menu|Shutdown|Shutdown the Computer). 

- Leave it off for a couple of seconds, then power it back on. 
  Now both MIDI Input and MIDI Output should be enabled.

If the MPU-401 is in Basic Configuration 0001 already, you will need to
check some other basic things:

- Is the sequencing program set up correctly to record data from the proper
  inputs? (TBS-2000 ext. in)
- Are the cables attached correctly? (computer output to keyboard input,
  computer input to keyboard output)
- Is the IRQ available (ie any conflicts shown?) ...try a different IRQ
- Is the I/O range available? Try a different I/O.
