With S1v4, the Import Song Data feature was implemented. However, I don't think the feature is complete.
For instance, when you select a Song to import from, you cannot import bus or FX channels with no automation lanes. I've tested this. As long as there are no events or automation envelopes on a track, you are not given the option to import it.
Why is that a problem? Well, let's say I have Superior Drummer set up in multi-out to give me control of individual mics, and I have groups of mics bussed to subgroups for kick, snare, etc., and I have all the channels running to a drums subgroup with processing on it. I want to import just the bus channels I used as subgroups. Well, they don't have automation envelopes, and because they're bus channels, I can't put events on their respective tracks. So I can't import them without importing the instrument.
Or, what if I want to import pieces of my template at a time, so I pull in my DRUMS layout, then my KEYS, then FX, and so on. That's not possible if there are no events or envelopes on those tracks. In the case of FX, you really can't import them without first adding automation envelopes.
To make matters worse, you cannot import from Song templates. Why in the world is that the case? The first thing I tried to do with the S1v4 demo was import from a template. Why would I want to do that? Well, let's say I've already started on a song, or I've begun working on a project, and I need to bring in additional processing after recording the drums. Or, I've laid out the tracks as recorded and I want to bring in my FX "rack." I'd look for my template and import just the pieces I need.
So, I know it's not a bug, but there's really huge limitations on Import Song Data as it compares to Pro Tools' Import Session Data. If Studio One wants to be the next big professional-level player, I think it should incorporate as much of a professional toolset as possible. Hopefully others agree with me.
