Apple Logic Pro 9 - Manual (Page 301)

Note: There are diagonal lines running through each of the 16 sub-channel boxes. The
Port and Channel parameters are shown to the left of the Environment window.
4 Click the Port pop-up menu, then choose a new MIDI Out port for the Multi Instr. object.
Make sure that this port is different from the one used by the GM Device object.
5 Activate each sub-channel by clicking each sub-channel box. As you do, the diagonal line
disappears from each.
6 Click the Mixer button at the bottom of the Arrange window, and you’ll see 16 new (Multi
Instr.) channel strips.
Tip: Once an object has been created in the Environment (using any of the methods
described), you can Control-click (or right-click) track names in the track list. Choose a
port and sub-channel from the Reassign Track menu to quickly reassign tracks.
Setting Parameters for Instrument Channel Strips
When you choose a track that is assigned to either a MIDI or software instrument channel
strip, the Inspector’s Track Parameter box displays the parameters outlined in this section.
Changes to these parameters affect the entire channel strip, and all tracks routed to the
channel strip are affected. This is an important distinction to make, as some parameters,
such as transposition, are available as both a track and region parameter. To put this into
context, imagine a project with six tracks routed to the EXS24 mkII (with a drum kit loaded)
on instrument channel strip 1. You want to transpose the snare drum part (played by
regions on track 2) by two semitones. This will trigger a different snare drum sample.
• If you use the Region Parameter box Transposition parameter for all regions on track
2, things will go according to plan.
