Topic: Programmatically query Digi 9636/52 sample rate?

Hi,

I'm wondering if there's any way that I can ask a Digi card what its sample rate is?

I'm on Mac 10.5.8.

I know that I can see this through the driver interface, but I'm planning (or at least hoping) to write a menu bar item to display, but not alter, the card's current rate.

As a starting point, is there a command that I can enter in the Terminal which will return this?

Thanks.

The card's sample rate is the one of Core Audio, so you should ask for that. There is no way to ask that directly from the card.

Actually, though, that leads to another question:

I've set the Hammerfall to be the Master clock source, as I thought it had its own, internal, crystal.

From what you say though, it seems that it uses the computer's own timing instead. How 'good' is this? Should I be using an external clock source instead?

How much of a real-world difference would this make?

Thanks again.

No, that's not the case. Core Audio tells the card which sample rate to run at, but does not provide clock.
