Don't know how far along you are on this. Could you possibly use Pro Tools
LE or Pro Tools Free to move the samples and then export as an OMF?
Know anyone running Nuendo?
As you've mentioned, fhe file's graphic representation is going to be off
which makes editing a bear.

Could, but I would have to do it _every_ time I record a track while
software-monitoring. Given the time required to do it, pasting 322
samples at the head of each file might be quicker.
And while most of the time I'm in OS 9, there's no PT free in
OSX... For that matter, no record/playback delay compensation
_at all_ in Logic for OS X.

BTW, why all this? I record everything whith software monitoring , u
shouldn´t have a prob doing so.

Unless you are very lucky, you're kidding yourself - here's why:
First, is your record delay correctly set? If you have a 4/4 audio
click playing, and rerecord your monitoring outputs, is the
rerecorded click exactly on the beat? If not, then assuming you
are playing a real instrument in time with the click, and
monitoring at source, when you record it and play it back it won't
have the same timing as when you played it. If you use anything
but the lowest buffer settings it'll probably be noticeable to a
well-trained ear, or a drummer ;-)
Getting the record delay set works for recording material that you
were monitoring at source. But if you were monitoring through
Logic, you are of course hearing what you play a little later
(approx 2x the buffer size). So naturally, being a musician, you'll
subconsciously compensate by playing a little earlier, right? So
everything is still tight.
But when you record that software-monitored performance, it'll
be recorded with the record delay you calibrated for
source-monitored material - so it'll be recorded where you
_actually_ played it, not where you were hearing it - and when
you play it back it'll be now be _early_ compared to what you
were monitoring..
The big problem arises from Logic's highly inadequate record
delay calibration - there's only one adjustment available (the
"ASIO buffer delay IN"), and it's a very coarse adjusment (in
multiples of the ASIO buffer), not sample-accurate. You shouldn't
attempt to use the driver playback delay to compensate, because
it won't adjust the actual position on the Arrange page, and will
mess with the timing of all audio playback (which also makes
calibrating the record delay more difficult).
Ideally you need to be able to set a record delay in samples for
each input, which can be set according to whether you're
source-monitoring, software-monitoring, using analog inputs,
digital inputs, etc. And you don't want to monitor through that
record delay, which rules out using a simple sample delay plug
on each input. The ability to record a plugin without monitoring
through it would make all this go away...
I use a combination of source-monitoring for external FX returns
(you don't want to software-monitor those because it will screw
with the sound of any time-based FX) and software-monitoring
for most other inputs. It's not possible to correctly calibrate for
both with a single record delay calibration.
Why not just calibrate for the software-monitored inputs, and
adjust for the more infrequent source-monitored recordings
manually after the fact? Because the "ASIO buffer delay IN"
setting only allows for a maximum positive delay of +1 buffer,
which is not sufficient - I would need +2 buffers or more to
correctly calibrate the record delay for software-monitored
recordings (assuming it's accurate enough anyway, which it
probably isn't for most buffer sizes).
I come from a background of 4-track and 8-track tape recording,
where what you played was what went on tape, with respect to
timing. It's tempting to assume your computer and software
works just like a tapedeck, but it doesn't. If you haven't paid any
attention to calibrating the record delay for your system, and want
to scare the crap out of yourself by finding out just how
inaccurate it might be, run some tests.
I can post a testing procedure if you want.

Midi controller learn in Logic. Soft takeover. Lots of memories.
Tracks remember control assignments. Write track automation.
