Chapter 10 Working With Instruments and Effects 255
You can’t actually change the receive channel of a sub-channel in the multitimbral
synthesizer. This is only possible in a few models (and is not particularly useful when
using Logic Express, at any rate).
If the MIDI channel is set to All, you can edit the parameters of the whole multi
instrument object. A useful facility for globally changing the MIDI port (Port A, B, and
so on), for example.
Program, Volume, and Pan
The Program, Volume, and Pan parameters transmit program changes, volume
controller (CC #7), and pan controller (CC #10) information.
If the respective box is unchecked, the default value of the MIDI device itself is used.
A program change (a preset or patch number in your MIDI module) may be selected on
the right, via a pop-up menu. When dealing with multi instrument sub-channels,
sounds can be selected from a pop-up menu by name.
As an alternative, you can double-click on the track name (GM Device 1, for example).
This launches the Multi Instrument window.
Simply click on the name of the sound (synthesizer patch) that you want to use. Click
the close button at the top left to exit the window, or press Command-W. More details
on this window, including customization of patch names, can be found “Using the
Multi Instrument Window” on page 904.
To the right of the program number, there is an extra parameter which is used for Bank
Select. If your sound source receives Bank Select messages (MIDI controller #0 or #32—
check your synth manual for format details), you can switch between different banks,
each containing a maximum of 128 sounds.
For more on the other instrument parameters, see “Standard Instruments” on page 899.
