Apple Logic Pro 9 - Manual (Page 694)

On the left (Convert), you can see the parameters of the selected event definition, and
on the right you can define the parameters of the destination event type. The current
settings (of the source) are used as default values for the destination.
Select the Quantize Events checkbox to quantize the event positions to the Grid value
chosen in the right parameter field. If any Delay value is shown on the right, this is taken
into account by the quantization.
If you simply open the Convert Definition dialog, change the Grid value in the right field,
select the Quantize Events checkbox (and make no further alterations), the event positions
of the selected event definition lane will be quantized.
Using the Event Definition Parameter Box
You use the Event Definition Parameter box in the Inspector to alter the settings of the
selected event definition lane. The most important parameters are Status (and First Data
Byte). All display-related parameters are covered in
Changing the Grid and Beam Display .
Altering the Event Status
The event status determines the type of event controlled by each event definition lane.
Click-hold the arrows to the right of the Status line, and choose one of the following from
the pop-up menu:
• Fader: To define a fader event lane. Fader event data can be used to control any possible
parameter (except channel volume and pan, which use controllers). Fader data can
also be used to create meta events.
• Meta: To define a meta event lane. Meta events are internal Logic Pro commands that
can perform tasks such as screenset switching.
• Note: If you want to define a lane for a particular note pitch (perfect for drum
programming).
• Control: If you want to define a MIDI controller lane.
