8.5 projects in X1, X1A, X1B are a crapshoot

When X1B was released I posted a thread about this compatibility issue.

There are issues for some of us in that regard -- sorry you got bit too.

In my testing of my VVocal and bounce to clip issues, I have discovered the same thing.  Problems with any project from older versions of sonar.

BUT... I had no problems with a project created in Cakewalk Pro Audio!

Go figure!

Yep - this is exactly what I've found.

Projects created in 8.5.3 do NOT play at all well with X1.

Projects created totally inside X1b seem to be completely stable, though I've got a lot more testing to do before I'm convinced.

This may be totally irrelevant, but I have found what appears to be a cure/work around for opening old 8.5.3 and before projects that then end in X1a or b to crash.
 
I have found if you open your project in safe mode.  i.e. select the project to open and then Hold down the shift key before pressing OK or Open.
 
I then selectively load each plugging as I go,  I only load what I recognise and I do not load SONITUS EQ.
 
Once the project has loaded I save it with a change in the name, I have been adding X1b in the title, then close and reopen the project.
 
This, as I say appears, to work.  Yes you have to go and recreate your EQ which if you have lots of tracks, it is tedious but it is better than the alternative. There ain't gonna be a SONAR 8.5.4 or SONAR 9.x.x.  Beside the Pro Channel EQ is much sweeter.
 
If this is irrelevant then please ignore.

Jim, John, Max - some good points & food for thought there.

Will try this later on tonight & report back.

I think I am just going to give up at this point.  I might revisit X1 again someday, but my frustration level is through the roof.

In response to earlier posts, this is on the same machine as 8.5.3, and all plugins are still in place...Kontakt 2, 3, 4.

Once again, Sonar couldn't load the Kontakt 4 that is in the project (3 times).  I close down Sonar, add Kontakt 4 to a new track, close the project, re-open the 8.5.3 era project and Kontakt 4 is suddenly somewhat peachy....UNTIL

On 8.5-era projects, if I add an additional single instance of Kontakt 4 within X1.  I can play the sounds, but I can then never again run the transport in that project.  Yes, you read that right.  Until I remove that new instance, the transport will not let me click on PLAY.  The audio engine will not engage after the first attempt.   Remove the Kontakt instance, playback can happen.  Redo the insert of Kontakt 4, the problem returns.  This is freaking ridiculous and I am literally shouting at my computer.

All I needed to do was open am 8.5-era project, mute a piano track, and insert one part to replace it.  I guess I was just way too optimistic that I could do this in X1.

I have same problems with both! I've had crashes with both opening 8.5.3 projects and fresh one started with x1b within the first half hour of installing x1b! 8.5.3 and other daws on this pc work flawless....  (both projects were minimal with only a few tracks, the one that was started fresh in x1b was just 2 tracks, an audio and track w amplitube 3) after that i shut it off, was dissapointed...
i just don't get it! i had high hopes for x1,x1a and x1b.

I have tons of old projects that I load into X1 and have not had any problem except missing ports because I have changed hardware and missing plugins.

No project has not loaded or been a problem.  These go back to wrk files.
This is with all versions of Sonar. I do not load newer projects in older versions but I do the opposite all the time.

Perhaps try loading an old demo from an old version to see if you still have loading issues with it.
