My visit in the store lasted roughly 20 minutes for three reasons. 1 - I was in Glasgow traveling to the airport on holiday with my family, 2 - there, in the store were a lot of people, which resulted a huge noise of talks and sounds of other instruments and 3 - no White Grand sample on Nord Grand, which I missed a complete feeling of this instrument.
So, my testing of Nord Grand IMO is incomplete and insufficient, but it's always something.
Generally, the Nord Grand from the seat point does't look like a huge block, but again from an aesthetic point of view, it looks like a premium stage piano - not a flat board like the rest of nord instruments. Especially the upper red surface of the instrument looks beautiful.
Desktop of NG is the same simple as a Nord piano 4. The difference only is the control panel is oblique and panel buttons are quite close to the keyboard, which can actually results in accidental pressing of them, which actually also happened me twice while playing, so the key lock button is really desired in this instrument.
The keyboard has a very pleasant Ivory Touch imitation effect, without exaggerated structure and makes a very pleasant impression. The keyboard works almost quietly like in a digital pianos in full cabinet, which is due to the built-in velvet tape dampening the noise of keys, which has never been available before in any nord gears. The keyboard action in weight, IMO is medium enough (not too light, not too heavy), it has a noticeable escapement but the fast runs are not a problem.
Who knows Kawai ES8, MP7SE or CN27/37 will be know how this keyboard works. The third keyboard sensor has a deep range of operation, which results in it's a high usability.
Comparing to other keyboards - apart from NG, there were in the store also Nord Piano 4 and Yamaha CP88.
NP4 keyboard was clearly lighter than NG and the feeling of escapement was definitely less noticeable in NP4 than in the NG, not to mention the touch of plastic surface of NP4 keyboard. Yamaha CP88 keyboard also with Ivory Touch was slightly heavier. The difference in action between CP88 and NG is more about the character of the action. Personally, I don't like Yamahas keys action.
I am not writing anything about the sound, because on the board of the Nord Grand, were samples which every nord user know well (Royal Grand 3D, Amber Upright, etc.).
I need to try and play on NG at least once more time again but in full silence and also with included the White Grand sample on the board.
P.S. This week I will be trying Kawai ES8 and probably MP7SE. After 20th of July I will try Korg Grandstage.
