With initial help from this forum I have been able to run Garritan Jazz & Big Band and GPO simultaneously via Garritan Studio into Sibelius 4 which I use for composing. I have just bought Marching Band to access certain samples not available in the other two libraries but Studio does not appear to be seeing the new library. Is it possible to access these samples through studio? Any help much appreciated. PS I am not using these samples in real time - I add notes in Sibelius using mouse and keyboard.
