Good Afternoon!
I have a Yamaha S90 XS that I have been experiencing issues with recently...
What happens is I select the Perform/ Master Channels and play a voice called Lay it Down, mid way through playing a song the Voice will go from a More Piano/Synth Sound to a Strong Synth/ String sound. It's become quite distracting because we use it during performances and when it changes it throws all the instruments off...
I'm looking for a solution, please help!
Sorry, I cannot understand what you are describing.
I think you might be experiencing the change in timbre/brightness as you strike the keys harder, which can sometimes be jarring. Try adjusting the velocity parameters in the utility screen. Maybe try selecting a fixed velocity or a different velocity curve? Hope this suggestion helps!
