Yes !
The Yamaha OTS sound combinations are great
This is incredible to see how much effort Yamaha put on the perfection of the sound in every aspect
DSP, EQ, volumes, controllers...
Nothing is neglected
Such a high level of sound programmers and intelligence in their choice !
And they hide all the hard work so the musician can sit and play
This is also the missing point, when they don't really allow you to tune sounds and styles as good as they do
I actually have a PSR keyboard that includes only 2 RIGHT parts
This is interesting to load a Tyros 3 style in vArranger, and play the OTS sounds that have 3 RIGHT parts. The same PSR will sound a lot better
