250 Chapter 5 The Environment

-1- (0 to 127): defines the first data byte of the event. In some cases, such as pitch bend,

this is an actual data value. In other cases (MIDI controllers), this indicates the controller

type (volume, pan, and so on, as examples). In other cases, such as aftertouch, this byte

is unused.

Here is the meaning of the -1- parameter and fader position for each of the In and Out

definition choices:

Note On

The -1- parameter sets the pitch, and the fader position sets the velocity. This is most

useful as an In definition—for trapping specific notes and converting them to other

MIDI events, or simply monitoring their velocity. If you move a fader with an Out

definition set to Note On, a note-off MIDI event will immediately follow the note-on.

This might be useful for creating onscreen drum pads from button style faders, for

example.

P-Press

The -1- parameter sets the pitch, and the fader position sets the amount of Poly

Pressure (key pressure or polyphonic aftertouch).

Control

The -1- parameter sets the MIDI controller number (the controller type), and the fader

position sets the controller value. The controller type can actually be selected by name,

via the pull-down menu that appears when you click-hold on the -1- parameter.

Program Change

The -1- parameter is ignored. (In earlier versions of Logic, this sets the program bank.)

The fader position determines the program number.

C-Press

The -1- parameter is ignored. The fader position sets the channel pressure

(monophonic aftertouch) amount.

PitchBd

The -1- parameter sets the pitch bend LSB, and the fader position sets the MSB.

Typically, you would set the -1- parameter to 0, and use the fader to control the “coarse”

pitch bend amount. A -1- setting of 0, and a fader position of 64 results in no pitch

bend.

SysEx (see “Overview” on page 256) and Switcher/Meta are special functions of the

faders.
