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
