Bachus,
I doubt we will ever see more than 1 arpeggiator on the arranger... but who knows, I might be wrong. There is the possibility that the 4 Multi Pads could become like the Performances on the Motif... 4 live arpeggiators.
I submitted a suggestion to Yamaha that they provide a firmware update to allow the Live Control settings to be saved in registrations. They came back with an answer from Japan engineers that
"it can't be done" but they fixed that in the Genos and then the PSR S975. I think they had to re-write the OS code to do that. That's a major improvement.
I hope they will listen to us who know how important encoder knob/controls are over standard pots. They are far superior for performance. On my Motif Rack XS I can change a parameter using the encoder knobs. The display shows the original setting and the current (edited) setting so I can always go back to the original setting if I want. And of coarse encoders offer a smooth transition from the current setting to a new setting, whereas the standard pots always cause a "jump" in the parameter setting.
Yamaha need to offer better technology for the price we are paying. They have already implemented these features on other keyboards. Their arranger boards are good... but they could be better. Those who don't understand the issue will say stop complaining... don't buy a Yamaha arranger... But I will predict that if Yamaha do what you and I have suggested (make a better keyboard) then those who would say... stop wining will acknowledge that
we were right.
