If you’re going to use vArranger with the Montage, then use the Steinberg Halion Sonic 2 as your sound source, as a lot of the voices in it were programmed by the Motif designers, so it will integrate beautifully.

A Montage performance has 8 tracks for local use and 8 other tracks with Montage sounds can be use by an external source like a DAW or Varranger..
So in the end you could play the Montage performance and have 8 tracks of a style using Montage sounds... The strong point is that you have super Yamaha Montage sounds both for your keyboard performance as well as for the styletracks...
I am a huge fan of Halion 5, a superb allin package by Steinway, which seems to be a great way to expand Varranger..
