+ONLY — when ON , this parameter causes the pattern waveform to be “rec-
tified” about the level midway between the peak to peak values of the
normal waveform as shown in the following illustration.
Slits
Press KURL MODE to highlight the SLITS function. Slits is an effect in which
the source video is split into a number of parallel slits. The width of the slits
may be uniform or random, and an angle may be specified. An offset func-
tion is provided which controls the amount of displacement of alternating
slits in opposite directions (to cause a transition type effect).
Slit modulation patterns include sine wave, triangular wave, square wave,
ramp, circle, random, pulse, or trapezoidal wave (same as Ripple Patterns
in previous menu).
Soft knob controls are provided which change the phase of the Slits, and the
amplitude, frequency, and phase of the modulation pattern.
