Massive X Gui latency

Hi,

I,m using Cubase 10.0.2 on Windows 7 & there seems to be a Gui latency with Massive X.

When moving the mod wheel on my controller keyboard the Gui mod wheel (or Pitch wheel ) is very slow to respond, i.e some sort of latency.:synth:

Anyone else with the same problem as have never seem this before on any other virtual instrument I have.

PS the PC is old, 2011 but have never had the above before.confoosed
