Not much more to add on this OP other than say, I have been on PCIe AES for years. I've switched to an RME MADI PCIe interface last night and did 64 tracks at 88.2 including midi and vsti processing without a glitch. I'm summing 32 tracks AD and my system is shockingly fast and very stable. The latency is barely noticeable. I even went so far as to loop one bar and do numerous overdubs for a min. It never lost sync and the overdubs recorded seamlessly. I am thrilled! Hope that helps someone wondering. MADI is very cool.
