I have an enomorous template with over 1200 tracks in it. Many composers I know have gigantic templates as well. I have been using Cubase for many years and it suffers some slow loading issues etc. from large track counts. It is magnified big time by the number of midi ports.
If you take a blank Cubase sequence add 1000 midi tracks and add a couple of VE PRO 5 plugins and then save and close it. Now change the ports in VE PRO to populate 48 ports. Try opening your sequence you just saved. It will now probably take about 10 minutes per VE PRO plug in that you put in the sequence to open.
Making suggestions about how to manage the ports, etc. does not fix certain issues that can not be avoided with large templates. I currently use 14 ports per plug and it is super slow already. Big templates are a balancing act. If you could implement these "sub" smaller plugs it would really help in a HUGE way and allow much more flexibility in how many of us set up across multiple machines.
Thanks,
Danny
