Advanced latency compensation

Yes, that makes sense.

We won't catch all cases this way, think of aux sends in a track. But I'd say it's a step forward and covers some real world cases.

Thanks Rui.

• For audio tracks it works as expected.
• The audio of MIDI tracks gets compensated for plugin latency in the track (as before) but not for plugin latency in the audio bus.

It's magic: switching latency compensation in the bus has an immediate effect while playback is running. Switching latency compensation in a track needs stopping/starting playback.

Thanks for this positive outlook, Rui.

Now using external hardware is even more fun. And Inserts can be (ab)used to report a fake latency, so Qtractor can compensate the latency of plugins that don't report it to the host. Complicated setups with additional aux sends to other buses can be handled/aligned manually, e.g. by inserting LSP Compensation Delay if the destination bus of an aux send has a lower latency than the track's audio bus. Of course this can be pushed to extremes and might lead to a delay function within aux sends some day or a whole rewrite of the latency compensation. Until that I am confident that all real world problems are already solvable with Qtractor as it is now.
