• Program, Volume, and Pan: Transmit program changes, volume controller (CC #7), and
pan controller (CC #10) information. If the respective box is unselected, the default
value of the MIDI device itself is used.
A program change (a preset or patch number in your MIDI module) can 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 the track name (GM Device 1, for example). This
opens the Multi-Instrument window.
Click the name of the sound (synthesizer patch) that you want to use. Click the close
button at the top-left corner to close the window, or press Command-W. For further
details about this window, including customization of patch names, see
.
To the right of the program number is an extra parameter that 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 information on other instrument parameters, see
• Delay > Auto Compensated Delay Offset: This is the same as the Delay > Delay in
Milliseconds setting, except that the current plug-in latency compensation plus the
audio hardware output delay is added to the MIDI data transmission. This setting is
ideal when the outputs of classic MIDI sound sources are mixed with Logic Express’s
outputs using an external mixing desk. Using the Auto Compensated Delay Offset
setting makes sure that audio from Logic Express and audio from the MIDI-controlled
external hardware appears on the external mixing desk at the same time. When this
setting is chosen, the parameter label changes from “Delay” to “Auto Delay.”
