Nice job on your Custom Drums. I have made some drum kit editing in (Tyros 4) Voice Creator in the past, but nothing like your beautifully made full Custom kits. Those added dubstep notes near the top end of the keyboard were a nice variation to the usual percussion type sounds.
I like your Tyros 2-61 + Tyros 5-76 twin setup. I have had a Tyros 3 + Tyros 4 twinset, Tyros 4 + Tyros 5 twinset, but the ultimate is my present Tyros 5-61 + Tyros 5-61 combo. Maybe a Tyros 5-61 + Tyros 6-61 combo next year, plus additional drum kit editing and features.
Nice of you to share your video.
