Erratic behavior like hanging up on notes, not evaluating or evaluating wrong,
may happen if there is additional information being sent from a MIDI keyboard 
into the computer. If a keyboard is transmitting MIDI data on MIDI channels 
other than just MIDI channel 1 unpredictable things may happen.

To check to see if your keyboard is transmitting on more than one channel, 
do the MIDI Input test in Soundcheck. You should only see lights blinking 
on Channel 1 and System.

Please make sure you MIDI keyboard is ONLY transmitting on MIDI channel 1. 
We couldn't tell you exactly how to do this because each MIDI keyboard is 
different, so you'll want to look at the owner's manual for instructions.
