Mac Mini late 2006 onboard soundcard latency

A Mac Mini late 2006 ( A1176 ) ...
AULab shows over 300 frames 'safety offset' for in and about the same for out
Is this a coreaudio thing ? Hardware is pecified with 14 frames input / output
I remember a dual MDD working as 'trigger module' of kicks live very fast
( 5ms or less ) via onboard soundcard, Mac Minis are newer and slower with onboard audio
???
Thanks for sharing experiences
Best

The chip is a Core Duo. It was ok in its day but not something I would look at twice anymore. The last OS it can run is 10.7 in the 32bit kernel.
Although the numbers you quoted do not feel right, when it's that old and antiquated by modern standards, why waste time dealing with it?
A Core2 Duo (mid 2007) at least, can run 64bit even if it's not a stellar performer.

Sorry, I was may be not clear...
I'm talking about onboard soundcard latency...
I have several of these upgraded to Core 2 Duo, I think 2.4 GHz, and they perform
definively better - DP 7.24 - than the dual 1.2 G4 MDDs...
This latency ( safety offset ) must be an OS X thing...or as I said because of the onboard soundcard.
I will check out with a 896mk3 later. ( time... ) but then firewire adds up too...
If possible I want to use these Minis as drum kick trigger like I used a G4 MDD successfully
Thanks for replies
and best regards

I checked with an 896mk3H...
RAX buffer set to 64 samples, 1 instance of apTrigga
The triggered kick is about 16ms late compared to the original
I don't get the math, 64 samples x 2 = 128 samples i/o, plus hardware about 60 samples,
still it shouldn't be 16 ms...
Argh...
Any drummers around who uses live triggering with a Mac and can help ?
