SPIN
SPIN sets the rate of WANDER. SPIN is a log control
with a period of 8. In English, this means that if you
increase SPIN by eight units, the amount of audible
spin increases by a factor of two. There is always some
spin--even with SPIN at 0.
There is a trade-off between NUMBER and SPIN;
lower NUMBERs increase spin speed.
Note: After changing SPIN or LENGTH, the voices
take a while to stabilize. Faster SPIN settings stabil-
ize faster.
SLOPE
SLOPE controls the amplitude of the delays over time.
Figure 4.2 shows the decay characteristic with SLOPE
all the way down. The variation in level is linear on a log
scale as shown. Overall level is adjusted to keep the
loudness constant. Figure 4.3 shows the decay char-
acteristic with SLOPE midway up. Figure 4.4 shows the
decay characteristic with SLOPE all the way up.
LENGTH
The delay of each voice is equal to the LENGTH setting
divided by the number of voices set with NUMBER.
WANDER
With WANDER set to 0, the voices are absolutely fixed
to their constant ratio apart. An impulse put in without
wander will sound like a single delay line with feedback.
As you add wander, delays go backwards and forwards
randomly in respect to each other.
