C5 and MOTU Ethno Instrument 2

There are three levels of audio file quality offered on this Rompler for transferring to audio tracks in C5. The first two work fine but when I switch to the third (labelled Sample2), the audio cuts out on the Rompler and I have to reload.
MOTU are suggesting it’s Cubase as they’ve no record on it happening else where.
It’s not a common piece of equipment but I hoped someone here might have experience of it. :nerd: :wink:
