The advent of GPO4 surprised and perplexed me. Where are 2 and 3? Assuming that I am using what would be considered GPO1 along with GJ&BB, I wonder how I missed those updates.
Whatever the case, as can be seen in the provided screen-shot, I use Garritan libraries in conjunction with Overture SE 3.6.1 which, of course, came bundled with GPO for a time.
This leads me to the crux of this post—
Will I be able to upgrade to future and more advanced Garritan products like GPO4, or will my use of Overture SE prohibit any such upgrades? For at this point I see no likelihood of acquiring another notation program to replace this one.
I greatly appreciate any help on this matter.
