https://cinelerra-gg.org/download/CinelerraGG_Manual/Displaying_tracks_Gange... i see it described there as well === NOTES: When in Gang Channels or Gang Media mode, if the first audio track is not disarmed, but any of its connected channel tracks are, the disarm of those channels are ignored and all channels are treated as being armed. This is to be consistent with the purpose of using this mode; the purpose being that any edits to the first master track are automatically propagated to all other channels. == but again, I never used Ardour (or any audio DAW) but I thought idea of locked/protected tracks still common there? At very minimum it gives you more fine control about editing... note, my implementation of hidden preference actually done in localsession, too, just like gang_mode itself. Also I think this line has a typo (ares instead of are) ? "More details ares described next about master tracks" Finally, is there a way to numerate chapters in html output? ( so reference to numbered chapter can be easily found by browser's search function.)
