Ah, OK, good to know, thanks! It seems to work for WAV files though.
I assumed that if I start all sources at the same position and then always call getNextAudioBlock in a loop for all of them, they should stay in sync?
(you suggested something similar, but back in 2009, so it might be outdated Synchronising audio tracks)
Or is there any built-in sync mechanism in Juce? So far I didn’t find any…
