A very common set up for those of us using the montage for gigging is to have a weighted controller on the lower tier (in my case an SL-88) and the montage 7 on the upper tier. The Montage 7 being the slave. Many users of the Montage have complained that the Part MIDI receive channel cannot be assigned. I have owned all Motifs from the Classic to the XF series. Parts were customizable to receive channel number assignment. They were not fixed to the respective part number but could be adapted to work seamlessly with the master. Not with the Montage. It can only receive Ch 1 on Part 1, Ch 2 on Part 2, Ch 3 on Part 3 etc. This is totally unacceptable and unjustified. Fortunately, I have Cantabile 3 software that allows me to create the once popular midi receive part channel assignment virtually. It is $99 a year (I have been using it as my VST player on my windows machine). I was teetering between the Kronos and the Montage. The audio interface integrated into the Montage was the selling point for me. I never thought that the MIDI ch Receive for each part would suddenly be removed. However, it has. My question is: Will Yamaha change this serious deficiency? I love the Montage, otherwise. I plan to keep it. I am disgusted with the choice to hard code the Part Midi Receive channel.
