Thank you Ian for clarifying as I'm not yet familiar with the Tyros system. I'll keep my fingers crossed that a pc editor will be made available, even if after the KB comes out. However, in my case it's not a deal breaker because the available T5(and T4)sounds I heard are already a major reason why I chose to order it as is as an entry into Yamaha sounds. So, if I take these sounds that I already like and just tweak them on the most typical parameters via the onboard settings, I'm sure I can find a good sound palette for my needs. On the hand, if this is a player's only keyboard and they want to do deep sound design, I understand how the lack of a pc editor could be an issue.
