[CM] import-events tempo-change

[Ville Isomottonen]

Hi

I'm very new with this, and my question is:

I'm importing midi-file(format 1) events with "import-events", and I 
need to know the tempo changes.

There's a seq for the track 0 that includes that information.
There are midimessages with time and msg number and data in that seq. 
And I suppose midimsg 10368 = tempo change.
But I don't know the meaning of values in the "data #(3 7 161 32)" ??
How can I read the tempo-change from it, in milliseconds ??

Thanks,
