Doepfer

Hello, please is it possible to know since when it features the Fatar TP/40GH keybed ?
I have read that pre 2011 versions used another model (TP10/MDR)

On the same forum few users had complained for a supposed clunking noise while triggering the keys at low volume control room, reason of this would be the “case” resonance. Can anyone comment this? I have no chance to test this master keyboard but it would surprise me if the physical noise would sounds unbearably loud: couldn’t the case be filled with antiresonance material? Or those people are used to play as quite as a laptop speaker? The instrument is also on sale without case, few bucks less than the normal price… is this option for those who find the keybed so acoustically clumsy maybe? 

Is the USB interface class compliant (no need of driver installation), as usual on other Doepfer Midi interfaces?

Owners feedback on this instrument “at large” would be precious to me, any other consideration is heartily welcome.

Best regards
Diego
