Furthermore, a look at LUG member John Pitcairn's website www.opuslocus.com
revealed the following... thanks, John:

That just leaves the option of manually moving the recorded audio. The
Arrange window is not sample-accurate, so the only obvious way to do this is
by moving the anchor point in the Sample Editor. Proceed as follows…
To move an audio region by minus X samples:
1. Open the audio region in the Sample Editor.
2. Ensure the Sample Editor Edit >> Update Arrange Position menu is
unchecked.
3. Move the region anchor point (not the region start point) to the right
by X samples.
4. Close the Sample Editor.
To move an audio region by plus X samples:
1. Open the audio region in the Sample Editor.
2. Ensure the Sample Editor Edit >> Update Arrange Position menu is
checked.
3. Move the region anchor point (not the region start point) to the right
by X samples.
4. Uncheck the Sample Editor Edit >> Update Arrange Position menu.
5. Move the region anchor point back where it was originally.
OK, that's fine for single regions, but it’s a tad mouse-intensive (I suffer
from RSI), and it’s a royal pain in the arse if you regularly record
multitrack takes. There is another method — if you can record at an
arbitrary tempo, use this formula to get the correct tempo for a 1-tick
nudge which equals the required shift in samples:
tempo = samplerate / (nudge x 16)
For my Multiface, which needs a post-record nudge of -128 samples in OS X,
at 44.1kHz that's:
tempo = 44100 / (128 x 16)
tempo = 44100 / 2048
tempo = 21.5332 bpm
So at 21.5332 bpm, 1 tick = 128 samples. If I record at that tempo, then I
can simply assign a key command to nudge -1 tick in the Arrange after
recording. Multiples of that are probably a little more practical, ie record
at 86.1328bpm and nudge -4 ticks. I have a list of the “magic” tempo
multiples for my hardware in a marker in my Autoload.
If your tempo is already set to something else and you have existing stuff
in the Arrange, all is not lost. Record, then:
1. Select all (watch out for track-locked and hidden tracks)
2. SMPTE-lock.
3. Change the tempo to a multiple of the “magic” tempo you worked out.
4. Select only the newly recorded audio.
5. SMPTE-unlock.
6. Nudge.
7. SMPTE-lock.
8. Change the tempo back to the original tempo.
9. Select all.
10. SMPTE-unlock.
If you have tempo-changes in the song, it's presumably the tempo at the
region start that affects the nudge amount, so you'd just change that tempo
while SMPTE-locked and leave the rest of the tempo-changes alone. I haven't
tested this …
Not exactly ideal, but if you can do it it's a lot quicker than opening each
region from a multitrack take individually and moving the anchor point with
the mouse (owww my wrist!)...
