Yamaha Montage Instruments and .ins file

[The Wizz]

Dan,

I am having issues using .INS MODE with Yamaha Montage.
Although all Instrument banks are displayed, only Montage GM Banks are played regardless of what instruments selected.

How do I play correctly Montage instruments to accompanied left hand sounds with vArranger2 .INS MODE?

Are there settings to be made on the Yamaha Montage?

Regards.
