”GAUSSN.WFM” = noise()

”SINE.WFM” = sin(2 * pi * scale)

”RAMP.WFM” = 2 * scale –1

”TRIANGLE.WFM” = tri(2 * pi * scale)

”SQUARE.WFM” = sqr(2 * pi * scale)

See Figure 2–45 on page 2–74 to see the contents of the subseq.seq file, and

Figure 2–48 on page 2–78 to see the contents of the mainseq.seq file.

Figure 3–66 on page 3–207 shows the gaussn.wfm and ramp.wfm waveforms

created in above equation.
