When no sequence is defined, all of the pattern data is output as a single
waveform as shown in Figure 3-62. If a sequence is defined, the sequence
ordering and repeat (Repeat Count) functions are applied as shown in Figure
3-63. The extended sequence functions (trigger input, event jump, etc.) are
ignored.

Pattern data is output not according to the internal clock, but rather according to
a clock signal generated manually with the STEP/EVENT button. Pattern data
is output using the method used by the Repeat item.
Pattern data is output as defined by the sequence. The extended sequence
functions (trigger input, event jump, etc.) are valid during this output. The
Repeat Count item setting is used for sequences for which the repeat count is
not set to Infinite. Figure 3-64 shows an example of an enhanced mode
sequence. Also refer to the description of the EDIT menu Make Sequence menu
on page 3-57.
