Regarding teasers, Yamaha announced over the summer on yamahasynth.com that the Montage was being discontinued and a new one was coming out in October. I guess their synth division is different than their arranger division.
yamahasynth.com is interesting because it seems to be an official Yamaha site that has a full synth focused forum on it as well as a whole bunch of tutorial articles posted by their experts. Guys like Blake Angelos, Hans Heinkel and Joel Borg give regular tutorials on the TechTalk channel. Additionally, they have Soundmondo, a free sharing website where users can post and share their voice edits, tagged in various genres, based off of the presets. Imagine if arranger users could share styles that they altered or tweaked, legally of course. That would open up a whole new world for people who want to try other user's styles in genres that go beyond the typical presets. Yamaha has nothing like this for their arranger market for some reason. When is the last time they offered an expansion pack? Guys like Martin Harris, Peter Baartman, Gabriel Aldort do have scattered YouTube demos on the various Yamaha arrangers, but many of them are from years past. I see that Martin Harris is a Sr. Manager at Yamaha. Perhaps it is time for him to step up and build something similar for their arranger customer base rather than have this constant rumor mill on if next arranger launch is imminent. If they don't want to put the resources into tutorials and user sharing, it kind of makes you wonder what they think is the future of arranger keyboards.
Currently, only this forum offers the best for arranger users for a place to go. Just an observation. I originally wasn't intending to write this much!
