Have you got the latest firmware on your panorama (Panorama_P6_FW_V011403.bin is the last file i can see on my machine)? My bet would be that.
Also are you running the latest (1.3.85) beta of Nektarine?
That’s what i’m running.
Also are you copying
From:-
C:\Users\USERNAME\Documents\Nektar\Nektarine\Mapping Files\Instruments
To:
C:\Users\USERNAME\Documents\Nektar\Common\Mapping Files\Instruments
I’ve had some oddities when setting up in the past and had to reflash the firmware, or do a factory reset - and that sorted out any initial install problems. Only the once though, when i moved from Logic (Mac) to Cubase (Win10).
