I spent yesterday building a logic environment that splits the keyboard into 3 sections and has a few toggles to do octaves and activate brass and timpani hits. I've got the toggles mapped to a midi foot controller and the brass levels mapped to volume pedals.
The strings and brass were created from the aggressive multis, but then modified a bit - changing ports for my needs and getting rid of most of the keyswitched stuff.
It's pretty epic!! The strings are cranking away at ~90 poly and brass at 18 at the end.
The strings/brass were played in a one take manner.
All the melodic instruments are GPO. Most percussion is true strike tension.
I've been enjoying listening to you talented folks here. Thought I'd drop something - I'm a little excited about it
And if anyone wants the environment - which could be imported into logic 8, I'll probably be making it available after a little clean up and a small readme.txt authoring.
