Like Stratman, I too have been using Sonar for a long time (Since cakewalk 2004). Now, I will preface my statement with the fact that I DO save often just to keep from losing important stuff as I would do in ANY software program I use.
All of my cakewalk experience until X1, was in the Home Stduio versions. I dropped the whole dime on the full X1 when it first came out. I didnt work well with my new system and had a lot of small problems that got repaired over time with updates. I actually went backwards and bought Sonar 8 full, and Cakewalk was nice enough to provide me with the 8.5 upgrade links so that I could have all the tools. Once upgraded, 8.5.3 worked flawlessly on my system. I waited thru X-1 and when it went to X2 I upgraded immediately. With a couple of insignificant glitches (still no lost work due to saving), X2 has performed to expectations.
Now before you jump all over me, Bub I will admit to NOT being a high end Recording studio user, but I do a lot of work with Midi combined with audio using an 6 year old audiophile 2496. I record live sometimes, but mostly in house audio and midi equalling close to 80 tracks depending upon my needs. Also, I use a lot of effects and until I get into multiple softsynths I dont have any real problems. Even still they are mostly user controlled error on my part. With a some research, and using the forum, I get what I need in plenty of time.
Sorry to hear that youve been having a lot of problems with it, but if moving on to something better will help you get the job done then you probably should. The way it reads in the last 3 pages there isnt any amount of convincing you that Sonar is a good platform, but from where I sit... its the best yet (for me)
Hope you find a form of a solution that suits you.
