Delay line objects have the following parameters:
Thru Original checkbox: If selected, the original events are passed thru. If unselected, 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.
Transposition pop-up menu: Defines the transposition of note events per repeat.
Velocity field: Defines the change in the velocity values of note events per repeat.
