FWIW
You have the correct idea in your opening Post.
Put your programs and VST's in the C drive
Everything else that can be installed do so on the 2nd drive.
If sonar places the synths on the c drive let it be. they do not take that much space, if there is an update then sonar knows where to look to fix it and at least you know that it will work right out of the gate......
It's the library's and samples, loops, downloads etc that will eat up your space and also slow your programs down. so by seperating them you give the programs a chance to operate more effeciently and thus less issues....
Also just a thought ...
on the VST's what I do is create
One master folder and then sub folder it for different bit programs (32 bit, 64 bit Cakewalk and jbridge) then all my VST's dll files are in ONE PLACE so all I need to do then is point my plug in manager to that one master folder and everything gets scanned....no missies...
Here is what it looks like
C\
Program folder \
ALL VST"S \
(now comes the the subfolders)
32 bit Vst's (I place all 32 bit VST's in this folder and yes you can subfolder this for individual Plugs like IK MultiMedia, Kerovee etc...)
64 bit Vst's (I place all 64 bit VST's in this folder and yes you can subfolder this for individual plug ins as well)
Cakewalk VST's (I put all my Cake walk VST's in this folder)
Jbridge (anything I want jbridge to see I use this folder)
Now all i do is point my plug in manager to the "All VST" folder on the
c drive and everything get's scanned and no one get's missed.......
If I have any issues I know exactly where to look for things.........clean
Hope this makes sense
