The answer to the question MBedesem.
Just a few steps.
The first step is to truly see the midi file, delete unwanted channel, make transpose to the simplest key signature (CMaj).
The second step is, to divide into sections (Main A, Main B, Intro, Ending, etc.).
The third step, make transpose in the sections (except Intro and Ending section), so that the whole section was in a single tone (exp: CMaj7).
The fourth step is to configure parameters of CASM (Chord Root, Chord Type, NTR, NTT, PTR ect.), for more information, also You will find the manual for the Yamaha keyboard.
