Finally. Something I hadn't thought of. Getting past the alloted object limit. But surely that
isn't why Emagic decided to have both types. I'm just dying to know a more legitimate
reason. I've been pondering it for a few days and I'm sure there must be something I've
overlooked. It's a bit frustrating.
Logic didn't just spring fully formed into all it is today. The entire audio part was added on, and expanded. In fact, AFAIK nothing has been added to midi for years. So there may be more than one way of doing things (e.g. track mute and channel mute), or there may have started with something like busses, and then decided to expand to aux's but not want to hose those people who already using buses. Or perhaps the buss will always be there because its modeled on a hardware mixer buss which many people are familiar with, whereas a free floating aux does not have a physical model.
A lot of things are modeled on "real" mixers and such. What stops them from making a mixer that is perpindicular to the existing one. Wouldn't it be useful to have an arrange page where there was a horizontal fader on each track. In this way, you could see more tracks and see them in the places you have been working with them on the arrange page, rather than having a vertical view (arrange) and horizontal view (mixer) like protools. But real mixers are horizontal so they don't get too creative.
