When loading a MIDI file into Band in a Box, all tracks of the MIDI file will be on the Melody channel.

But to access them on a channel by channel basis and change patches, use the big round green SEQ (Sequencer) button in the toolbar to open another window, which should be rather self explanatory from there, also has mouseover tips and Help section. Here we can mute certain channels if desired, as well as change patches.
