My impression is that criticism, constructive or otherwise, of Yamaha products is not well received on the PSR Tutorial. There are Yamaha cheerleaders there.

I'm very careful of what I say on that site.

I still have two Yamaha keyboards and usually only post on that site if I need help with those keyboards.
