I think it should be. I bought the HZ Pro during BF, downloaded all 122Gbs only to be very disappointed with the bug on the JXL Surdo. It's not a cheap library, the quality is amazing - and I've watched the Spitfire promo about all the mics they used and all the different mixes included etc. Would have been good if they'd done some thorough beta testing first though to iron out basic bugs such as a 9th RR on the JXL surdo. It was one of the first things I noticed and, after reading the comments here about the issue being reported months ago, I feel a little fobbed off....I guess this issue is not big enough to warrant a update of its own.
I willMaybe it's best to contact Spitfire and share your findings here.
