Genos has limitations compared to other boards, just like other boards have limitations compared to Genos, (This is not new and is just the way the OS works, hence the reason you must try before you buy) however while I am not fully familiar with the Genos I am familiar with Yamaha in general, and to me that looks like he has deliberately setup the Yamaha to suit his cause rather than get the best out of it.
There is also the question of if it didn’t do what he wanted, why did he buy it?
