Delay Line Objects
A delay line object repeats (echoes) MIDI events passing through it, at intervals ranging
from one tick to 256 whole notes.

As with the arpeggiator, you need to place a delay line object in the MIDI signal path,
and Logic Pro must be in playback mode. The echoes of each incoming event are sent,
sequentially, to each cabled output of the delay line object: event 1 to cable 1, event 2
to cable 2, and so on. Obviously, if only one cable is connected, then all events are sent
to that output.
The delay line can send up to 99 repeats, at intervals ranging from one tick to 256 whole
notes. You can also suppress the original note events.
The Delay Line’s Parameter Box
The delay line’s Parameter box offers the following parameters:
• Thru Original checkbox: If this parameter is turned on, the original events are passed
thru. If the parameter is turned off, the original events are suppressed (which means
that only the echoes will be heard).
• Repeats field: Defines the number of event repeats. The 0 setting turns the delay line
off.
• Delay field: The delay time between the individual repeats. The left value is in divisions,
and the right value in ticks.
