Hello,
I have two RME cards installed in one PC: HDSP 9632 PCI, and HDSP AES32 PCI.
A few questions:

1. Clocking. I sync my AES32 as a slave to my Yamaha converter (master). Can I somehow sync 9632 to AES32 via internal connectors? Would they then work both as slaves to my Yamaha converter? I do not have the word clock add-on for 9632.

2. For some reason, ProTools DAW only sees 9632, but does not see the AES32. Could I route AES32 inputs to 9632 ADAT inputs? Would there be any extra latency involved?

3. I am using an E drum kit connected via midi to 9632, which outputs real time samples through SuperiorDrummer software. Now that I have AES32, I have another option to use its midi input instead of 9632. Which option is better latency-wise, having in mind that in both cases I am using 9632 for real time analog output? In other words, is
DrumModule->9632 MidiIn -> 9632 Analog Out  better latency-wise than
DrumModule->AES32 MidiIn->9632 Analog Out?

Many thanks..
