Apple Logic Pro 9 - Manual (Page 303)

• No Reset: Turn on the No Reset parameter to prevent reset messages from being sent
to this channel strip. This can be useful if controllers are being used for nonmusical
purposes, such as mixer automation. The Logic Pro > Preferences > MIDI > Reset
Messages pane determines what reset messages are normally sent, but these messages
are not sent to No Reset instruments.
• Style : Whenever a MIDI region is created on one of the tracks routed to a given channel
strip, it is assigned the staff style set in the Style pop-up menu. If Auto is chosen,
Logic Pro picks an appropriate style based on the pitch range of the notes in the region.
Tip: You can change a MIDI region’s staff style at any time in the Display Parameter
box of the Score Editor.
Setting Software Instrument Channel Strip Parameters
The following parameters are specific to software instrument channel strips.
• MIDI Channel: This parameter sets the MIDI channel strip used by the software
instrument.
• Freeze Mode: The Freeze Mode parameter allows you to define the point at which the
signal on the selected channel strip object is frozen: before the signal is fed into the
first effect plug-in (Source Only) or the entire signal including all effect plug-ins (Pre
Fader).
Setting External MIDI Channel Strip Parameters
The following parameters are specific to External MIDI channel strips.
• Port: Defines the physical MIDI output that data is sent to. Your MIDI sound module is
connected to this MIDI output connector.
• Channel: Defines the channel used for MIDI output by the instrument track, allowing
your “real” instrument to receive the data.
You can also alter the MIDI channel of an external MIDI instrument part by choosing
another sub-channel of the current multi-instrument.
A sub-channel is one of 16 possible MIDI channels or parts that can be played by a
multi-instrument object. It goes without saying that the external MIDI synthesizer
(represented by the multi-instrument object) needs to be capable of playing on more
than one MIDI channel for sub-channel selection to be useful.
You can’t actually change the receive channel of a sub-channel in the multi-timbral
synthesizer. This is only possible in a few models (and is not particularly useful when
using Logic Pro, at any rate).
If the MIDI channel is set to All, you can edit the parameters of the whole
multi-instrument object. This is a useful feature for globally changing the MIDI port
(Port A, B, and so on), for example.
