Of particular interest are:
Row 1 & 2
: Notice, when
Gate Stretching = ON
, that the gate length of each stage’s single pulse
is stretched beyond the limits of one clock pulse, and now occupies 75% of the entire
note/stage width.
Row 3 & 4
: Here, the pulse is divided by /3. Because GATE TYPE = MULTI and Stage 1 is
4-pulses long, this generates an extra gate (after the first three pulses) on the fourth
pulse of the first stage.
Notice that, when
Gate Stretching = ON
(ROW 4), the gate length of each pulse
increases to fill 75% of the note’s length, rather than 75% of one clock pulse (which is
what happens when
Gate Stretching = OFF
). Also notice that gates cannot stretch
beyond the boundary of a Stage. So (on ROW 4) the gate that’s triggered on Stage 1,
Pulse 4 will go low one ”tick” (1/96th of a clock pulse) prior to Stage 2.
Row 5 & 6
: Here, the pulse is divided by /2. Because GATE TYPE = MULTI and both Stage 1 and
Stage 3 are longer than 2 clock pulses, those two stages generate an extra gate after
two clock pulses.
Besides the effect of Note Stretching on ROW 6, notice also how its final Gate is
truncated (ending one tick shy of the end of Stage 3) since gates cannot stretch
beyond Stage boundaries.
Row 7 & 8
: Here, with GATE TYPE = MULTI, we are dividing the pulse by /1. This results in a new
pulse being generated every clock pulse. Therefore, it doesn’t matter whether
Gate Stretching is on or off, because each note is one clock pulse long, resulting in
identical gate lengths.
