I'll try to summarize the situation for the little I remember (correct me if I'm wrong): those who work with audio always have to deal with a very large number of tracks that make it difficult to display on the timeline. Glen requested (BT#433) a feature to tie the tracks (channels) into a single line (track). Ardour does it using only one line (track) for the "n" channels; instead in Cinelerra each channel is an independent track. GG came up with the usual ingenious (original and complicated!) idea of Master/Slave tracks and Gang modes. I had hoped that it would become a way to link video tracks with their audio tracks, so that sync would not be lost during editing, but it was not possible! If we are talking about Gang modes then we are talking about audio tracks and in this case the behavior is different from the Cinelerra standard: the slaves (hidden) tracks undergo the same editing as the master track regardless of whether they are armed or disarmed (BT#577). I, who don't do audio mixing/editing, find it antintuitive, because I'm used to Cinelerra's std behavior, but it's actually the normal behavior of DAWs that group the various channels in a line and it doesn't make sense to think of them as some armed and some not. Perhaps this should be explained better in the manual. Moreover, if we want to implement the standard behavior of Cinerella, so that an unarmed track is never modified whether it is visible or not, we must be sure that it is a separate function from the current Gang modes, creating a new type of gang and explaining very well its function, because the risk of confusion is great and the subject is already complicated. Patches 1 and 2 are great because they simply add the ability to use In/Out points with "Attach effects". Patches 3, 0004 and 0005 (I haven't tried this one yet) should be part of a new Gang mode (Gang arm? Gang Cin? Gang Std?). PS: I tried to put the 0005 patch without recompiling, but I don't see any difference. Do I need to recompile?
