create slice markers with protools

[mick...@gmail.com]

I madea useful discovery over the weekend and dont know if its been reported before!

I use protools by choice for editing audio and have used logic a few times for adding markers that qlab will read which
is fairly easy but frustrating if i want sample accuracy or looping which ive already sorted in protools.

I found that if I add tempo changes in protools where i want my markers - it has to be an actual change no smaller than .001
of bpm for every marker - then as well as exporting the audio from protools I create an empty midi track and export
a midi file - if I load both files into logic my tempo changes are registered in logic via the midi file. The cherry on the cake
is if i bounce the audio out with logic the tempo changes register as markers on the audio file without me evn creating markers in
logic and appear in qlab. Note that if you put markers into logic as well you get two sets of markers in qlab which is a disaster
waiting to happen. Dont forget to hit the "export markers with audio" option - I dont actually know if this is essential?

So in protools audio with no actual beat map adjusting tempos has no effect on the audio but just transfers the marker points.
I was actually using some tempo mapped audio but wanted to create loop points within it that werent on zero crossings and clicked
in protools and qlab - so I had to do extra mapping for my loops selecting zero crossings just off the grid by samples and
then beat identifying to insert tempo changes at just the right points if fractionally off grid. This is all much easier for me in
protools than logic where all i now have to do is load up and bounce out. Note to self - if you make a tempo change less than .001
which protools will do - logic will see no change and wont create a tempo marker for that point.

As an aside I also discovered that garageband will no longer pass markers to qlab in v9/10 my old v6 will still do it and will work in
mavericks. Unfortunately its never imported tempo changes from midi files so the above trick is out.
