I think my first two year's worth of beats were each an excuse to learn something, wether that was new tools or random self imposed limitations. Whatever is was, every one had a background task.
You're clearly on the same wavelength as what I was badly waffling about above. You don't have to change everything you're already doing. But as you say, the inability to edit the odd mis-step is just wasting precious time IMO.
Likewise, I don't get too involved in the 'correct' sonics of a track... great for dancefloor impact and all that, but that's not me. Plus I mostly listen to old music where different track fill different frequencies in different ways or even not at all. But even saying that, I still want the finished thing to have some degree of overall balance/coherence - occasionally I listen to something on some different speakers say and one sound might be annoying dull or bright or whatever. Just being able to go in after the fact and spend 5 mins balancing out a mix or fix a real clanger is so valuable to me. Applied to you, I don't think that would rob from your musician's skills and work ethic either, just present your vision in the best possible way.
Again, not neccesarily anything that applies to you, but I often feel production nerds and musicians could be a lot better off by learning a little of the other's skills. In fact maybe it does apply to you as you're really good example of these things succesfully colliding...
Buy anyway, so many times I've heard music made on a computer that's technically outstanding and yet all I can think is this person wouldn't know a good tune, or riff or even chord if it bit them on the arse. Conversely, I lost count how many times I've encountered great musicians with a wealth of musical talent, who kill live shows but then produce the most sterile, dull album possible - pretty much always because they are only interested in being a musician and think if the music and lyrics are strong enough, nothing else matters. Bullshit. Pretty much all the old good music in existence in the history of recorded music is partnership between great musicians and the skills and techniques in the studio that captured and ultimately immortalised their vision. It's why record collectors fetishize certain labels and studios, they had the artists AND the sound.
(sorry, tangent rant there... on what was already a thread tangent )
