The program PadMaker-Midi will do this job:
PadMaker-Midi is a tool for creating a Multipad based upon the patterns from one or more midi or pad files.
With it you can:
♦ Create a pad by selecting an area of a midi or multipad using the mouse and on-screen options. No typing is required.
♦ Edit an existing pad by replacing one or more sections from other pads or sections of midis.
♦ Audition the pattern selected on the PC or PSR.
♦ Edit the Voice, Volume, Pan, Reverb, Chorus, Tempo and Brightness, Chord Follow and Repeat parameters for each pad. Editing tools are provided for transposing each pad based upon the notes used in the pattern.
