Victor writes: "Setting up multi-timbral multi-channel instruments such Garritan Personal Orchestra, SampleTank, or Logic's own EXS24, is not entirely trivial. It takes a couple of tricks both in the environment and the arrange window. In this tutorial I will show you how to set up GPO, using a string section (2 violins, viola, cello, bass) as example".

This will be of enormous benefit to Logic Users. Enjoy this tutorial amd be sure to visit Victors web page at:

Thank you Victor!
