I think I got it now, please correct me if I'm wrong.

HostTime is a timer that starts from zero when my Mac starts. It cannot be set to zero (or anything else), the timer increases until it wraps around. So...

If I want to make a sequencer I can use it this way:

When recording the sequence:
1 - I set a variable (recordstarttimestamp) to value of HostTime at the moment I press the record button.

2 - Every time I recieve midi I set the timestamp to HostTime-recordstarttimestamp and save.

When playing back the sequence:
1 - I set a variable (playstarttimestamp) to value of HostTime at the moment I press the play button.

2 - I send out my midi messages with timestamp set to playstarttimestamp+recorded timestamps.

Is this the correct method?

Best regards Peter

Hi!

I wonder what HostTime really is? Is it a timer that starts ticking as soon I turn on my Mac and never stop? And a timer that can never be reset to zero?

Let us say that I record a sequence of midi bytes. What do I need to do with the timestamp to be able to play them back later? I mean, the timestamp that comes in is too old to be usefull in the future so some kind of calculating (adding) is needed.

Best regards Peter
