I noticed nothing new - the behavior and the reason seems to be exactly the one I tried to explain in my 3:th post, and if this is the issue, it is different from the original bug that was fixed. The channel swap itself seems fine, but when doing the swapping while playing, after the swap channel manager 'resets' for example channel volume to the channel volume setting given in the general tab(try putting correct channel volumes to channel settings instead of applying then at the beginning of the mod with effects). Anyway, I can't think of any good reason why the swapping should act differently if playing the mod or not.
