Some may want to record say a kick on the first pass and snare on the second etc. But where this falls down with new clips being generated each time is you might want to do say a kick and snare hits first pass and some more kick and snare parts second time around. Then it is easier to add all the parts into the one clip. Same for piano or bass parts etc. You might only get part of the piano part the first time around and want to complete the part the second time around. Especially if you are not a great keyboard player but want to create an interesting or slightly hard part in stages or cycles in the loop. All in real time of course. eg with feel etc..
It is not hard either to expand pitches onto separate tracks in Studio One either. So we can just as easily put all the stuff into one clip, get it right and then expand it out onto separate tracks for individual processing etc just as easy as you guys can merge clips.
Sounds more sensible to me. Merge first then split out later if you really need to. All I know is that merging stuff into clip certainly works for me much better as it does many others in most DAW's. What I found though that was real revelation for me was the ability to jump midi tracks on the fly and add parts in here and there over a range of instruments. Sonar simply cannot do this at all. I know not everyone does this either but I have found it quite useful at times. You can even switch input quantizing on and off as required too as well go in and out of record for rehearsal reasons all while looping and never stopping.
We can also switch the takes to layers option on and generate clips for each pass too just as you guys are doing now. Which of course is excellent for doing say a solo over a section and then comp later etc..Which of course you also may need to do.
Like I said for some this is
revelation. This and other reasons such as excellent timing are the main reasons why I actually left Sonar and went to another DAW. So for some it
can be serious show stopper. It just depends on your workflow I guess and how important some things are for you in terms of how you might build up midi parts.
