hello,
it appears that logic sets incorrect values for
outDeltaSampleOffsetToNextBeat. instead of giving the number of samples
until the next beat, logic passes either 0 or a very large number, such as
4294967287.
someone sent an email about this to the list in 2004 about Logic 6. I've
attached this email below. I'm using Logic Pro 7.2.3, and it seems this
bug still hasn't been corrected. any ideas what's going on here? thanks
a lot!

Subject: Host transport start/stop and song position

Hello
I have some questions regarding the hosts songs position and hosts
transport notification.
1) Does it exist any way to get the information if the host transport is
moving(playing) or not(stopped). I have looked in the documentation and
also in the mailing list archive but i cant find any clear answer on this
question. I dont want to use beat(beatAndTempoProc) information to detect
if the host is playing or not because then i will miss some
samples(comparing old song position with new song position).
2) Why is the outCurrentBeat(beatAndTempoProc) start (song position 0 in
the host) different depending on host. For for example in Logic 6 the
outCurrentBeat start position is 0.0 and in Digital Performer 4 it is 1.0,
why isn't this the same?
3) outDeltaSampleOffsetToNextBeat(HostCallback_GetMusicalTimeLocation)
seems to give very strange results in Logic 6. The value is switching
between 0 and a very large number, an example 4294967287, 0,0,4294967290
if you read the documentation...
Taken from the documentation
...outDeltaSampleOffsetToNextBeat Will contain the number of samples until
the next whole beat from the start sample of the current rendering
buffer....
Is this correct behavior?
4) Is there any easy way to get the song position in samples(without
converting)? I cant use AudioTimeStamp.mSampleTime because this has
nothing to do with the song position this increases even if host transport
is not moving(Logic 6).
Regards
Hans Mvller
