I like the Roland's approach with the digital pads and where they have implemented a processor in the device. This is a big step forward in a world where everything soon are going to be digital.
I don't believe that such a function would be more fragile. I would say it is rather smart to implement it in that way to create more control and get more trigger functions, but still be able to control and repackage Roland's IP in the cymbal/pad.
Yes, it is properity system...but I really wonder how advanced it really is. They will control all triggering and send it over the data bus, but but I do believe the logics is handled in the TD-50. I would be impressed if the td-50 really could tell the chip in the pad to be more sensitive or trigger in another certain way etc. (If so ... It can't be too hard to check what's going on that data bus. )
In my opinion...The TD-50 will be a hybrid between the Roland past and the next future generation modules where every pad will be digital.
Anyway...it was a nice launch!
