I have two computer so this is the master computer who only runs the daw and the audio. Im planning to upgrade the master but even though the templates can get large only a small fraction of it plays at the same time.Excuse me but...
These two things don't make sense to me when you sum them up. You evidently have a rather limited computer but at the same time state that 256 tracks is not enough for the work you do.
I really don't think a (really rather high) limitation on the number of tracks available is going to be a bottleneck for you unless you reach hundreds of gigabytes to run such an amount of tracks simultaneously. And if your template exceeds that number of tracks at this point I sincerely believe you should re-examine your workflow.
This honestly seems more like an unhelpful mental hang-up than an actual practical problem.
My advise would be to re-evaluate what it *actually* is you need to get your work done and if a track limit of such proportions should really be a bottleneck.
Personally, I'd sooner work with multiple different templates than I'd ever want to reach such a number of tracks in my projects.
