One of the dangers of the "cut and paste" methodology of DAW's and associated software is the loss of real playing skill and technique. I'm sure (if I had the money) I could record some songs and through the use of plugins/software/pitch correction etc I could make my recordings sound much better than I really am. And while artists have been employing various methods throughout the years to make themselves sound better on a recording, the foundation for everything is the ability to play/sing properly in the first place. I think that an MTR forces you to play and sing properly, moreso than a DAW/software setup where things can be "repaired" with a few mouse clicks. If all you ever want to do is be a recording artist, then fine but if you plan to perform live, you'd better have your chops going or it'll be ugly..
This is sort of true, but not really for us mere mortals. A DAW can make the next pop singer starlet sound great, even though she's never seen the stage in her 17 years of life. She's going to suck live. However, the guys in the big budget studio are going to be working on that one vocal track for a long, long, long time to get it to sound good. It's not as easy as just tossing on some Autotune.
For us non-big budget studio mere mortals, yes, we'll still cut and paste, but you can do that on any MTR out there, too, with almost as much ease. THere's just not as much other control, like time stretching, automating various parameters of things other then just volume, etc.
A lousy take on a DAW can turn into something usable or at least decent with some work, but a lousy take on an MTR usually can't be made to sound any better. The example I gave in an earlier post typifies this. The 3-4 noticable flubs that I had on the one take couldn't be fixed with an MTR, so I've got to go back to the studio at a later day. If we used a DAW, I'll bet that the track could have been edited within an hour or two so that it would sound pretty good. Instead, I've got to go back, which will take all day.
That said, at home, I have no desire to spend all day fixing tracks. A good take is still absolutely paramount to just about anything else when recording with a DAW, MTR, or any other recording platform.
For us mere mortals, a DAW at home can get you really close to making a truely professional sounding recording, where it's much harder to do with an MTR. For me, that's the bottom line, as I am trying to get nearly professional sounding recordings. If you're not, then an MTR may be tons easier for you.
