Mtm takes midi files as input and creates MUP files as output It allows assigning keys individually to each track, translation of track numbers to different staff numbers, header creation, and different beamstyles for each time signature. However, despite all the limitations I list below, mtm has saved me tens of hours of work entering notes. I do a lot of complex brass quintet arrangements, and with mtm, it generally takes me fifteen minutes cleanup on a 350 bar piece as opposed to three-four (or more!) hours of note entry
