Actually, I don't think some of the standalones are that bad, as long as you know what they can and can't do. I'm using
a Roland VS1824CD to record an album, and it really isn't a bad 24 bit 96khz HD recorder. It's A-D converter is fair, although I judge it inferior to say, an Alesis HD24. Its preamps suck, and they are virtually always bypassed. I don't use the COSM effects (or any others, most of the time), nor am I doing complex editing on it, although I think I could, if I was good enough.
So what is it to me? A HD recorder with a built in mixer. Yeah, it records 18 tracks, but seeing as how they give me only 12 track faders, I think of it as a 12 tracker, and that's about perfect for me. If I get through this project without a single knob or button on this puppy blowing, I'll be impressed (fingers crossed). So far, so good. Before I went to dedicated high speed CD duplication, I probably burned 800-1000 various CD's on this machine, mostly without a hitch.
I feed it with a small boatload of outboard gear, just as you would an HD24. On the other hand, I can take it to remote locations, and yeah, I still don't really like it's pres, so I'll take, say, a DMP3 for 2 somewhat more believable channels. I probably will go to a dedicated HD recorder soon, and the Roland will probably stick around as a remote unit. One mixer coming up! The outboard gear will feed an Alesis or a Mackie just as well as the Roland. It may not be the greatest HD recorder around, but I have been able to make it serve my needs pretty well. The preamps suck, but the mixer isn't bad. YMMV-Richie
