Not sure I understand what advantage you see here, so I ask...

Can we have a timeline for time from beginning of performance, continuing
even if the pause control is engaged, and another timeline for time from
beginning of performance, but exactly synchronized to position in the score?
Call them performance time, and score time.

Since I proposed Conductor Time and Score Time, I don't object. 8-) But what's your view on how tempo behaves and how beats are counted after a pause? ... just leave the most recent tempo & time sig in effect?


I would think both would be
available in sample frames and in musical units.

What do you mean by available? In the event record for every event, or that they would be convertible when needed? Also, they wouldn't be mutually convertible.


I don't think tempo alone will do it; perhaps the host is ramping from a
slower tempo to a faster tempo thanks to a command, say from a
accelerando/ritardando knob, while the pause control is engaged. This could
make sense in algorithmically assisted live performance.

What are you saying, the accel./rit. would continue after the pause and you don't want it to? Or that it wouldn't continue but you want it to? Couldn't this handled be a host implementation choice?

 Well, In VST you can query the host tempo, even when the transport is
 stopped.  Tempo synced effects (like echos etc), dosn't need the song
 position (only the tempo).

So I think musical clocking can go away when you press stop.

 Best Regards,
