Instead of using the Open Command, try Import Chords Command. This allows access to chord analysis, tempo, the number of bars, and key signature synced with the BIAB Style which defaults to disabled and must be enabled.

Use File->Import->Import chords from Midi File (Midi Chord Wizard )

I opened three of Jonel's LX files from his zip folder: "Abide in me"; "old rugged cross", and "take my hand" as well as three midi files from my hard drive.

All six files synced and played correctly between the midi file and BIAB Style.

<< Most of those appear to me to make odd assumptions about which MIDI channel should go where and what patches to use. Probably there's some logic, but I lost patience. >>

Gordon is correct here. In this instance the user might have to manually set a channel because the midi composer may not use generally accepted channel designations such as Melody on Channel 4, Bass on Channel 2, Piano on Channel 3 or Drums on Channel 10 and so forth.

There are two options, let Import Chords automatically set the channels and place the melody channel. (Default)

or

Import the chords and place all of the midi file channels on the Melody Track.

If the midi file is imported onto the Melody Track and the user doesn't know the instrument placement channels, open the Sequencer to display all of the midi channels and numbers. Then the user can manually set the correct channels and import again to overwrite the current settings.

The Sequencer is an option to easily determine the channels and set these channels to match the midi file.
