I am new to Logic but have read all the manuals now, and they say that you can automate ALL controls in the Track Mixer, including Bus Send on/off buttons. I have been able to automate most functions of the Track Mixer but cannot get the Bus Send on/off buttons to automate at all. The buttons work manually (by Option clicking), and I can automate the Send "levels" to a bus, but trying either the Touch, Latch or even Write modes will not record on/off activity on the Send buttons. Is this a bug? The only workaround is to automate the Send levels instead of just turning on/ off the Sends. This of course is much more work, since you have to individually create each send level change for each time you want to activate a Bus effect, rather than setting a single send level to the Bus and simply turning off/on the send. Anyone have this problem too?
