Deflection Error

Simulates an unstable CRT deflection coil: image roll, line bend, sync jitter, and flicker, layered independently.

Parameter	Control	Range	Notes
Amount	Trough	0 to 1
Roll Speed	Trough	0 to 3
Line Bend	Trough	0 to 1
Sync Jitter	Trough	0 to 1
Flicker Amount	Trough	0 to 1
Flicker Rate	Trough	0.5 to 60Hz
Roll Mode	Selector	Seamless, Tear Band	UI-only; not modulation-assignable.
Video Standard	Selector	NTSC, PAL	UI-only; not modulation-assignable. Independent of Scan Lines’ own copy of this control.

NOTE: setting Roll Speed to 0 stops the roll wherever it currently sits, part-way shifted, rather than returning the image to unrolled. Resetting Roll Speed does not undo it either. A Reset Roll button snaps the roll back to unrolled; it is the only control that does.
