The Prime Time III Program<br />
The Prime Time algorithm provides left and right control<br />
mechanisms for predelay, high frequency rolloff<br />
(6db/octave), max pitch shift, speed, time event length,<br />
feedback, x-feedback, input delay, and delay pan. The<br />
input signal goes into a stereo delay line which has<br />
three modulation controls: MAX L&R, SPEED L&R,<br />
and WINDOW L & R. The glide is performed inside the<br />
delay lines, thus it is possible to have large amounts of<br />
delay but retain control of the overall modulation effect.<br />
These three glide parameters interact with each other.<br />
Speed is the rate of climb (acceleration slope) to<br />
maximum pitch shift; MAX is maximum amount of pitch<br />
shift; WIN is the time event length. WIN defines the<br />
amount of time over which the entire glide event takes<br />
place. The actual time that it takes a cycle of modulation<br />
to complete is determined by speed and the MAX<br />
pitch shift. The delay will always speed up to MAX and<br />
then back down again, which takes a certain amount of<br />
time. This time can be lengthened by setting WIN large.<br />
This allows long flanges with low pitch shifts to be<br />
achieved. Window is specified in samples, a unit of<br />
time. Feedback paths are routed outputs to inputs and<br />
x-feedbacks are routed outputs to opposite inputs. An<br />
input delay is provided to match the pre-delay for “over<br />
the top” type flanges while mixing “internally” in the box.<br />
The treble filter is functionally placed at the output of the<br />
algorithm.<br />
About the Parameters<br />
Page 1<br />
SPD (Speed )<br />
SPD controls the acceleration rate to reach maximum<br />
pitch shift. There are two controls for SPD, one for the<br />
left and one for the right.<br />
MAX (Maximum Pitch Shift)<br />
MAX sets the maximum amount of equivalent pitch<br />
shift. Each step is equivalent to 6 cents of pitch shift.<br />
The total maximum pitch shift can be set for 180 cents<br />
— almost a full tone. There are two independent<br />
controls for left and right.<br />
WIN (Window)<br />
Left and Right WIN controls define the minimum<br />
amount of time over which the entire glide event takes.<br />
WIN is specified in samples, a unit of time.<br />
