Different parts or variations for Intro, Verse, Chorus, Bridge & Endings when building songs like building patterns in SD3. EZkeys has different variations in the MIDI library packs you can build upon. I just finished a country riff for a friend to use from the Country Music MIDI Pack as an example I have many different EZkeys MIDI Packs for different styles of music. I am a guitar player not a drummer or keyboard musician.
