Tell us more about what you do as a musician.
If you have a midi keyboard (99.9% of all keyboards these days are midi) you can easily record the midi data into the midi tracks and assign a synth to play it as whatever instrument you wish. Editing is easy in midi.
Understand there is a learning curve. You will likely spend anywhere from a few days to a few months just getting a handle on the capabilities of MC6...depending on your existing skill level.
As far as user friendly and making tracks... yes it does make tracks, but you have to learn how it all works.... that's the learning curve part. I probably spent several months just messing around, working on simple tunes and learning how it all worked.
Do not let the Cakewalk propaganda fool you. While MC6 is classified as a "Beginners package" that is technically correct , however, MC6 is quite advanced and very capable of producing high quality recording output. I used MC4 for more than 3 years with excellent results before cross grading to X1 a few months back.
Once you get the hang of it, you will not even really need to think about the details.... you just turn it on and start recording your music.
So yes, it can do what you want, you just gotta take the time to learn it......and once you do..... then, it will be a "Cakewalk" to use it.
