Activating and Selecting Sub-Channels
To select a sub-channel for a specific MIDI channel number, click the appropriately
numbered button on the multi-instrument Object. The first time you click it, the sub-
channel is activated, making it available from the Instrument List. To avoid menu
clutter, you should only activate as many sub-channels as you actually need.
As with any other Environment Objects, you can remove sub-channels from the
Instrument List, by unchecking the icon box. The button for that sub-channel will then
be shown with a diagonal line through it. If you want to select the entire multi-
instrument rather than a particular sub-channel, click on the top edge of the multi-
instrument Object, or next to the icon.
In the above diagram, sub-channel 1 is selected, sub-channels 1 to 8 are activated, and
9 to 16 have been removed from the Instrument List.
The Sub-Channel Parameter Box
The sub-channel parameters are the same as those of standard instrument Objects (see
“Standard Instrument” on page 163). The only parameter you can not change is the
MIDI channel. (If you change the output port, this will affect the entire multi-instrument
and all other sub-channels.) If you try to change the channel from the Parameter box in
the Environment window you’ll see the following warning: “Channel protected! Please
select a sub-channel from the Instrument pull-down menu.” You can, however, change
the channel in the Arrange window’s Parameter box to a sub-channel shown in the
Instrument List (one without a slash through it on the multi-instrument), and the track’s
instrument will change to the selected sub-channel.
Cabling
To connect the output of an Environment Object directly to the input of a sub-channel,
hold down Option, and connect it the via the Instrument List (see “Cabling” on
page 160).
