Since the Yamaha gave the Montage a new pattern sequencer in the 3.0 update, and the new Roland Fantom also has a pattern style sequencer, I wanted to do a video comparing the two.
I think they both are useful, and both have their own strengths and weaknesses, hopefully this video gives a good overview of what you can get done with either one.
