LBH, many thanks for your input with this issue.
I've opened new projects to to see it that cures it but sadly it doesn't. I thought I'd post the problem here because, like you say, you are users and not official support. Although I haven't posted on here before I have visited on many occasions to read through the various posts. I have quite a lot of Arturia products and you guys know your stuff. Like I said earlier, thanks for your help and advice. I think it is a DAW problem as I can use Pigments through Analogue Lab problem free.
When I get a bit more time (can't use lockdown to sort problems out as I'm still working long shifts) I'll try get to the bottom of it.
Thanks again, you're a star for your imput.
