Nice post, dtb!
---> I agree with exactly what dtb just said.
My 2c, it doesn't come overnight. Guys like me & dtb have been doing home recording, playing, and collecting stuff for a long, long time.
F/I, putting together a MAJOR HOME RECORDING CD RELEASE, like THE DAVEMANIA COLLECTION, [my own cd creation, now available], also took years, and DAVEMANIA is just HOME recording... you know...
...Years to learn my chops. Years to learn how to record live sounds to tape. Years to practice, play, and jam, and whatever else I could do, day & night, and have fun w/music. Years to review, remix and dub MILES of ARCHIVAL tapes to WAV files, on the 'puter... [2 actual years for archival tape remix to WAV, on the DAVEMANIA project]...
Looking at it that way, the DAVEMANIA CD project was OVER 25 YEARS IN THE MAKING!! Wow, it adds up fast. [I'll turn 40 in weeks, but I don't feel too 'old',... yet].
I started learning to play guitar, 'seriously', when I was about 13, on what what was essentially a 'department store' electric guitar that somebody gave me, second hand, and for the first few years, it only had 5 STRINGS, [and 5 tuning pegs!]. I just played it that way, and I had to learn all over again, when I finally got a '6 string', HAHAHAH.
The first acoustic [classical] I had & played, at age 16, was also a department store clunker that was just given to me, but it worked!
I started out at 18, " pseudo-multitracking", with tape-to-tape kluges of cassette machines, which 'works', but sound quality is really awful. Try any more than 2 or 3 dub generations, and your primary tracks are lost in the hiss.
The first multitracker I got was a Tascam 244, when I was 21, which I still have to this day. It's a great machine, it still works great, and I've used it for many purposes: multitrack production, vocal/pa mixer, and submixer.
Anyway, enough about me.
We all start out as home recording NEWBIES, working from the ground up, and learn day by day as the recording process takes place. Recording & music is an art, as well as a science, and it's lots of fun, too..
Good luck w/your 424mkII/III. They are both great machines.
