My main concern is the delay induced by using a different converter other than the 192 i/o. Will i be able to offset it in the delay window ??? My plan is to use the KSP8 4 analog i/o to interface with my ouboard and the aes to set up 2 different stereo FX when this possible, all at the same time ?? Thanks
Tricky subject.

For tracking:

I just tracked an 11 song album this past weekend and used the KSP8 via the ADAT option card to get four extra tracks in on top of my Rosetta 800's 8 channels. The good news: it works. The bad news: the delay is ridiculous. We're not talking latency anymore. We're talking real delay relative to the Apogee.

The night before recording I did a number of tests and calculations and wrote a shortcut key (in Logic; I don't use PT) to nudge any selected tracks the exact sample length offset so that they would be in sample accurate sync with everything else. Worked fine. The next day, I recorded, hit the key, and the offset was off, for reasons I simply did not have time to investigate. Grrr. So I had to do very hasty ear-matches on the fly. I anticipated that there might be problems though so I only put scratch takes through the KSP8. They all got replaced with overdubs later through the Rosetta.

For insert I/O:

Things work a little better, but there's still a little latency when monitoring, which I expected, but as far as I can remember (I did this a couple of weeks ago; unrelated to this past weekend) on playback everything is fine, but that would be a function of your computer "knowing" where the recording is supposed to go sync-wise. I suppose that's where the PT delay window comes in.

Also, the KSP doesn't do 192khz if that's what you're recording at.

I don't know if any of that is a direct help but I guess the point is that yes, you should be prepared for having to compensate for convertors working at a different speed than your 192.
