When play MIDI file is play with a channel or channels according to MIDI’s sound track?  
Maybe I should split up the sound track and use the createSound method one by one。  
😂

Hi Wagner,

A MIDI file will only use one sound channel, regardless how many tracks/channels the MIDI file has internally. You are able to see and manipulate the MIDI channels through the low level API:
