I usually stay away from threads like this because whenever I give my opinion I get labeled a "fanboi", but I guess I'm in the mood for some abuse....
I truly hate that some of you are having so many issues, and I wish I was smart enough to help you out. Which ever DAW you find that will work for you is the one you should use. We're all just in it for the music, there should never be any hard feelings because the pile of code I use is different from the pile you use.
But the fact is, I've been using SONAR since version 3 and with the exception of a period of time when I was using a crap computer I've had minimal problems.
The pc I use now is an off the shelf HP, no special build or anything like that. I'm not an IT guy and I don't do tweaks, I'm just a guitar player. I just try like hell not to put anything weird or shady on my machine (not saying anybody here does, just sayin')
I have added memory (16 gigs) to my pc, and I use 3 different drives (one for programs, one for audio, one for samples and such). I try to keep my drivers up to date, but I don't use anything "cutting edge", no beta drivers or programs, etc. My interface is firewire and my pc doesn't have a TI firewire chipset.
I bought the best interface I could afford, after doing a lot of research and price shopping. I only use plug ins from established, reputable vendors. And although I'm running the 64 bit version of SONAR I use a lot of 32 bit plug ins.
My pc is hooked up to the internet and a wireless home network with a printer, two video game consoles, a DVR, and a TV.
I use a midi keyboard controller and a Behringer control surface.
Most of my projects are anywhere from 30 to 50 tracks with audio and soft synths and lots of plug ins. And I do a fair amount of live band recordings recording up to 12 tracks at a time.
I almost NEVER have any crashes, and when I do I've found they're usually caused by operator error.
I'm not saying all this to refute anything anybody else says or to be a smartass. I don't want to butt heads with anybody. I truly believe the folks who have problems are genuine in what they say and I hope they can get SONAR working for them or can find a DAW that is everything they look for and that makes them happy.
I just wanted to point out that it is possible to have SONAR work in a steady, reliable fashion without spending big bucks on a special build or doing some kind of voodoo incantations every time you fire the thing up.
And I certainly mean no disrespect to people like Jim who make such fabulous machines (wish I could afford one)
Happy New Year folks, hope the coming year is full of happiness and great music for you all.
