It seems to me that Yamaha would make a serious, but very serious mistake if it abandons the users of the SX series, since these arrangers are not cheap in many parts of the world. I think that the best way to keep your consumers happy should be with more updates of their software, versions 2.0 and 3.0, and of course, continue creating expansion packs of all kinds of music and why not think about more 60s, 70s, 80s and 90s music.
I think that Yamaha should consider that position, because that is how it has abandoned several of its consumers, such as the S series at the time. I think that several keyboardists should be organized to send an email of recommendations to Yamaha and hope to be heard. I hope so and we can have more updates with this great software on Genos and SX series.
