DELAY / TAP BPM
Once you turn
P1
, the lock icon disappears, the
Multiplier number turns white and
P1
becomes
a Delay control. Delay has a range of 1ms to
2.9 seconds, and a track without a BPM tag
will start at 500 ms. A slow turn gives 1ms
adjustment resolution, while a fast turn increases
the resolution to 200 ms per step. To get back
to the original BPM after adjusting Delay, select
a multiplier with
J1
, and the Multiplier number
changes to green. A single Tap of
P1
resyncs the
delay to the BPM.
J1
MULTIPLIER
Pressing
J1
toggles between normal transform
operation (indicator off) and the BPM Multiplier
(green indicator on). With the green indicator lit,
J1
adjusts the multiplier to 4, 2, 1, 3/4, ½, 1/4,
1/8, or 1/16. Multipliers that exceed the Delay
memory will not function and are grayed-out in
the software control panel. If BPM is set with
tapping, the multiplier is set to 1. The multiplier
is not reset when the BPM is set via the ID3 tag,
so your subsequent tracks can stay at x4 if you
wish. The active Multiplier is shown in green text
when locked to a BPM.
P2
FEEDBACk
Feedback is the amount of delayed signal fed
back to the delay input. Feedback minimum
to maximum is 11/3 rotations of
P2
. The Delay
clears after one circulation when Feedback is
brought to 0%. The Delay clears immediately
when uninserted, but changing the insert point
does not clear the feedback loop. This is useful
for adding PGM 2 Echo to the fading PGM 1
Echo. To clear the loop and start a fresh Echo
immediately, rapid double-click on the insert
point
B1
,
B2
,
B3
or
B4
.
J2
WET / DRY MIX
Pressing
J2
toggles between transform
operation (indicator off) and Wet / Dry control
(green indicator on). The hold echo default is
50% Wet / 50% Dry.
J2
has the same operation
on all effects.

DESECRATOR CONTROL
aSSIgnmentS
The Desecrator adds controlled distortion, from
fine dust to rusty metal spikes, by allowing
adjustment of bit-depth and sample rate without
dithering or anti-aliasing. Clipping can be a fine
shave, or enough for a wig! Signal flow and
control is shown below.

DRIVE LEVEL
The only function of
P1
(indicator off) is Drive
Level, adjusting from 0 dB to +24 dB in 32
uniform steps. To keep audio output level
constant, inverse gain is applied after the bit-
depth stage. A slight level reduction occurs
when clipping.
P1
has no second function when
using the Desecrator.
J1
has no function when using the Desecrator.
P2
SAMPLE RATE / BIT DEPTH
Sample Rate is the primary function of
P2
(indicator off) adjusting the sample rate from a
clean 44.1 kHz to a dirty 34 Hz over 32 steps
with 1/3-octave spacing.
Bit Depth is adjusted with the second function
of
P2
(green indicator on) adjusts from a creamy
24 bits to a crunchy 3 bits in 22 steps. Increasing
the
P1
Drive Level increases the spreadability
when bits are reduced to a single digit.
J2
WET / DRY MIX
Pressing
J2
toggles between transform
operation (indicator off) and Wet / Dry control
(green indicator on). The desecrator default is
100% wet.
J2
has the same operation on all
effects.
