The Korg T1 is the top of the line M/T Series synth. It has a full size 88 key weighted action keyboard and all the features of the EX upgrade standard. It became the master keyboard for many pro musicians because of it's "feel", A1 sound, and multiple Midi ports. The $4000.00 price tag probably had a lot to do with making it an exclusive board as well. Since this was a pro board they were generally taken good care of and used tend to be in very good condition. But they don't pop up for sale all that often and when they do usually still command a respectable sum. Sonically the synth is identical to a T3 EX/T2 EX. What you're really paying extra for is the full size keyboard and the weighted action. This was the only synth in the M/T Series line that could be upgraded from joystick to controller wheels.
