Hello You will certainly have MORE in a PRO Midi karaoke file than in a commercial score. And as a MIDI KAR can be displayed in a score editor ..you can make the score of your choice by hiding the staves which you don't think are useful. Often a MIDI KAR pro costs much less than a score. At PLANETE it is 5.50 the score + 2.20 shipping costs you are at 7.70 a Mid Kar Pro online is 5 euros with the advantage of the exchange in euro and directly in the PC.
