Efficiently clarified Alec!
The? then is: Will the EMC's program for the 5k do the same "good job" for the 7k?
Perhaps I should explain that because of hands disability, I can no longer play music and so have learned the laborious technic of making it, using step time sequencing, first with the capacity limits in the 2K and then in Cakewalk.
B-i-a-b has algorithmic programmed chord-based arrangements in which each track (instrument) can be opened,notated and then edited,finishing up with a midi/audio "Sibelius" type orchestral score.
I had hoped the far superior preset arrangements of 7k may have been similarly open-ended(no trade secrets!)
