I just resurrected an old 2008 x-serve and managed to get it updated to High Sierra just so I could be able to use Cubase 10.5 on it (the newest version that I've purchased) in order to go through 10 years worth of old projects I have that were written n pro 4 through 10.5.....

ANYWAY, am I dumb or is there no way to non-destructively edit midi tracks in it like the audio tracks work? When I split some midi drum's track nd spread it out I should be able to re-extend the events and still have the parts there past where I had split it...this is how the audio works and I swore that's how midi worked too, but I haven't used 10.5 in awhile, is it not capable of it? I've searched through walk throughs and shit and followed every preference setting they said in order to disable destructive midi editing but noe of them worked...this is nuts...Anybody have an answer to help?

Anyone who wonders why I'd want to use an 18 year old computer as a daw, well, it has 2 2.8ghz quad core Xeons in it with oodles of storage, it can run almost as many tracks and plugins as my newer M4, but I can't use all these intel plugins and 32 bit ones I own on apple silicon processors unfortunately....

 

Maybe post some screenshots to show exactly what is happening.
If you purchased Cubase 10.5 I believe you can install any version before that to use.
I have lots of projects saved as .all files from really early Cubase and if I remember right I think I had to use SX

 

I investigated further and cubase 7 just isn't capable of non-destructive midi event splitting, but audio is. I managed to get the project to work in 10.5 on the same computer, which is capable of it, so I had MOST of the plugins in 64 bit form on it for the project to work nearly perfect compared to the 32bit c7 version.

I'm not sure I'm familiar with .aII files, I do have some projects that go back to SX 2 but I haven't tried resurrecting them in modern cubase at all. Pretty much everything I've done in the last 18 years was on cubase 4, but I did upgrade to 10.5, and finally now 14. I was only using 7 because my 8.5 installation doesn't run very well for some reason. I'm assuming I should have installed cubase versions in sequential order but instead I think I ran 8.5 update again AFTER 10.5 was already installed to work out bugs after using dosdude installer to get up to high Sierra so I could run 10.5...its an irrelevant story anyway...I really hated losing my 32 bit plugins...and then I REALLY really hated losing my intel based vsts when I switched to apple silicon, so I've been enjoying being able to make some music with the old plugins. Enough time and evolution has passed for digital synths and fx plugins though that you can absolutely hear the quality difference between modern ones and ones from the 2000's. it's too bad there are some really great vsts from back then that have never been updated for modern use...on Macs anyway, I'd bet you can manage to get most old plugins to work still in windows, apple has too make sure to version lock things every chance they get.

 

Yes lots of 32-bit still work with jBridge (currently v1.77 beta) and Bridgewize by DDMF possibly available for Mac which also works OK on Windows but renames the plugins which I don't like as old projects do not see it.
Lots of the old Steiny plugins were unlocked by the witches on sister site if you search 'steinberg unlocked' ...but I think only for Windows
