Maybe the built-in effects tie-in with Cubase was putting off purchasers who use other DAWs? Odd, but sometimes having a feature that you can't use is worse than not having the feature at all. If they continue to receive updated drivers along with the MR816X, though, maybe it would be worth it to buy one of them on clearance. Maybe someone from Steinberg can answer. Will they continue to receiving driver support for new operating systems alongside the MR816X updates?
Cubase 7.5, Windows 7, Komplete 9, Spectrasonics stuff, a few other VIs, all through an old 1010lt.
