Both jacks output signals from -10V to +10V and are DC-coupled.
Clock Out and Loop Clk Out Jacks
The
Clock Out
jack outputs the stable master clock. It sends a clock that’s in sync
with the base clock (“beat” clock or Ping clock), whether you tapped in a tempo or
are using an external clock.
The
Loop Clk Out
jack
outputs a clock that’s in sync with the the loop/delay time.
All the clock outputs are quantized to the sample-rate. This insures they are jitter-
free (assuming your external clock has low jitter). The
Looping Delay
clocks are
some of the lowest jitter clocks available using Eurorack modules and should be
used whenever possible as a master clock.
The high voltage of the clock outputs is 8V. At fast clock speeds (audio rate), the
jacks output square waves.
In
Inf. Hold
mode, the clock goes high when the loop starts. This can be used to
trigger an envelope that VCA's the loop, for example.
Infinite Hold vs. 100% Feedback
Since setting
Feedback
to 100% (or close to 100%) and
Delay Feed
to 0% creates an infinite loop, the
Looping Delay
acts similarly to how it does when
Inf. Hold
is on. However, there are a few important
differences:
When
Inf. Hold
is on, you can adjust the
Time
parameter from one setting to another, and then back to
the original setting and it will sound exactly the same as it did to begin with. This is not the case with
Inf. Hold
off and
Feedback
at 100%; changing
Time
to a faster setting will actually record the new
shorter echoes into memory. Then when you turn back to the original slower
Time
setting, the
Looping
Delay
will be reading the shorter echoes and will repeat these in a longer echo. Therefore, even though
the
Time
setting is the same as it was originally, it will sound different.
Another difference is that when
Inf. Hold
is on, the
Feedback
knob has a special function: windowing.
Hold down
Inf. Hold
while turning
Feedback
to change the start and stop points of the loop (see
Windowing
section on page 9). There is no windowing with
Feedback
at 100% and
Delay Feed
at 0%.
The final difference is that with
Feedback
at 100% and
Delay Feed
at 0%, there is the ability to fade in
new sounds (layers) by fading up the
Delay Feed
knob, or by applying CV (perhaps an envelope) to
the
Delay Feed
CV jack. Or you can create blank spaces by turning Feedback down momentarily. The
loop is more dynamic and mutable, versus when
Inf. Hold
is on, the loop is static and immutable.
Why do I hear something I played a long time ago?
Notes on the nature of Looping Delays...
When
Inf. Hold
is off, the wet signal (i.e. whatever's being output from the
Send
jack) is continuously
recorded into memory, going back for about one and a half minutes. This means that the results of
every knob you twist and every bit of CV you input is being recorded into memory. Let's say you're
playing a melody into the
Looping Delay
with a nice rhythmic echo. If, for example, you change the
Time
parameter to make triplets for a moment, then switch back to eighth notes, then maybe bring
Feedback
up to make a “bloom”, then pull down
Delay Feed
to cut the audio out, etc... all of this will
be recorded into memory.
Normally you won't have to think about this: the
Looping Delay
operates “as you think it should”,
overwriting whatever it recorded 87 seconds ago with what you're playing now. But in some special
circumstances, you can access this old memory: Windowing large chunks in
Infinite Hold Mode
is the
primary method whereby you might hear some sounds that were recorded onto the “tape loop” several
minutes ago. Another way often happens when
Infinite Hold
and
Reverse
are toggled many times
while
Time
is being modulated. This can be surprising! But it also can be very useful.
