Looping Delay: Controls
A. FREEZE button. This latching button stops the recording of incoming audio. When
FREEZE is activated, the content of the audio buffer is looped (stutter effect). Size con-
trols the repeat time multiplication/division.
B. Blending parameter/Audio quality button. Selects which of the blending parameters
is controlled by the BLEND knob and CV input, or selects one of the four audio quality
settings. This engine is quite similar to the granular mode, except that it uses two over-
lapping grains synchronized with the most salient period of the sound. The grains are
carefully spliced so that they mesh well with each other (a technique similar to the “de-
glitching” of early pitch-shifters).
C. Load/Save button. See the “Advanced topics” section in the original manual.
D. PRE-DELAY DIV/MULT (POSITION). When a clock is sent to the Trig input, the Posi-
tion knob becomes a clock divider/multiplier for the pre-delay: at 12 o'clock, the pre-de-
lay takes the value of the clock length; clockwise, this clock is divided, and count-
er-clockwise it is multiplied following the rates: 1/16, 3/32, 1/8, 3/16, 1/4, 3/8, 1/2, 3/4, 1,
3/2, 2/1, 3/1, 4/1, 6/1, 8/1, 12/1 (borrowed from the Echophon). Note that the clock divi-
sion is limited to the largest division not exceeding the maximum delay; beyond this
point, the Position knob will have no effect. Note also that clock synchronization will be
more accurate with the Size knob fully counter-clockwise.
The Position knob response has been tweaked to allow easier dialing of very short
delays.
E. F. Grain SIZE and PITCH (transposition). SIZE controls the size of the overlapping
windows used for pitch-shifting – fully clockwise for a smooth result that might smear
transients, fully counterclockwise for a grainy, almost ring-modulated sound. When
Freeze is active and delay time is synced to an external clock, Size controls the repeat
time multiplication/division.
When the pitch is at 0, it now bypasses the pitch shifter completely. This drastically
enhances the delay quality when no pitch-shifting is done, avoiding the flanging effect
when the delay was used with feedback.
G. Audio INPUT GAIN, from -18dB to +6dB.
H. DIFFUSION (DENSITY) creates a granular diffusion effect based on all-pass filters.
