Well, have hit an interesting snag. The driver for the LT-FW allows you to change the ASIO buffer setting, but none of the values listed are compatible with PT9. It requires you to have a buffer of a multiple of 32 (32, 64, 128, 256, 512 or 1024) samples. None of these are available options for the LT-FW.

For the time being I have PT9 running with my Digi 002 Rack. I'm going to give it a little time to see if new drivers or a Pro Tools update will be forthcoming to fix this compatibility issue. If not I'm going to consider picking up a used HD Core card or possible the HD|Native route, since the Aurora with the LT-HD card has a proven track record.

Incidentally, I think this may be a PC-only issue, as the LT-FW card has native support with Macs instead of using a Lynx driver. I'm not certain of that, though.
