When using Tyros as a solo piano instrument, I have found some hard to describe weirdness in the way it performs. I can only give a partially adequate picture of my negative impression. Tyros seems very uneven, lower range seems louder.. playing with eq does not take away sufficiently the weirdness. It is more than this louder in lower range issue, there are other weirdnesses as well.
I have rarely experienced this unevenness in other keyboards. The Tyros is fine when used as it was designed, as an arranger, one man band set up. But in solo mode it underperforms. I am hoping there is something I am overlooking to make the experience more tolerable.
