Use this command to generate a clock pattern with a rate of <instrument
frequency> / <n>. The parameter <length> determines the length of the
sequence.
<n> = 2 generates 010101010101010101010…
<n> = 3 generates 001001001001001000100…
and so on.
Special case: With <n> = 0, the sequence defined by <length> is filled with
zeroes. If <n> = 1, the sequence is filled with ones.
