After that, I try my own Nord Piano 3 with coins and counterweights, I found the weight between lower keys and higher keys are different.
As the information from Fatar's website (http://www.fatar.com) , I known the TP40H is Balance Weighet, and the TP40GH is four zones Graded Action. But thru my test, the keybed of Nord Piano 3 was Graded Action but seems without four zones, it's similar to TP40GH.
I am wonder the answer of the keybed types.I also sent emails to both Nord and Fatar but still no answer, and I can't understand why there isn't any information about Graded Actions from official website.
Below is pictures and Videos
the Lower keys with 100g weight
the heigher keys with 80g weight
Watch on youtube.com
If anyone have Nord Piano 3, you can test and we should know is it the truth.I really want to know...
I am certainly it's Graded Actions, but why I can't see this information from official website and I waited almost one week for the email but no answer? seems strange
Another question is the TP40GH have 4 zones, is it means each zone have different weight? How to split? In my test, Piano 3 didn't have 4 zones,(not sure)...
So, it may be not a TP40GH...
