Channel stucture

Ch 2: Bass

Ch 4: melody (If original song has human voice it'll be replaced by a suitable intrument)
Ch 5: Second voice / choir / harmony voice
Ch 10: Drums / Percussion
Ch 16: Vocal Harmony Chords (VH)

Unlisted Midi-channels are used as needed. Of course, channels are not or differently used, if the original (the original song) should not require a corresponding assignment.

Good to know

• XF chords are stored as META Events (VH) only in the format XF and the Adaptations metioned above.
• If the adaptations were made after mid / end of 2013 or the Midifile has generally been produced or revised after that period, the channel assignment for channel 16 applies for the Formats GM, GS and XG.
