How Does It Work?#

Digital Delay is a stereo delay with manual millisecond timing, clock-sync operation, feedback filtering, and optional ping-pong crossfeed for moving repeats across the stereo field.

Quick Overview#

• It accepts stereo audio and outputs stereo audio.
• Time works in milliseconds until a valid clock is present at Clock.
• Div chooses the synced note division when clocked.
• Lo Cut and Hi Cut shape the feedback path so repeats can thin out or darken over time.
• Ping Pong crossfeeds the repeats between left and right.

Inputs And Outputs#

Port	Type	What It Does
In L	Audio	Left audio input.
In R	Audio	Right audio input. If unpatched, it follows In L.
Clock	Clock	Sync input for tempo-based delay time.
Time	CV	Modulates delay time.
FB	CV	Modulates feedback amount.
Out L	Audio	Left delay output.
Out R	Audio	Right delay output.

Controls Reference#

Control	Values	Default	Behavior
Time	1..2000 ms	250 ms	Sets the manual delay time when no clock is driving sync.
FB	0..0.95	0	Sets feedback amount.
Mix	0..1	0.5	Blends dry and delayed signal.
Hi Cut	1000..20000 Hz	12000 Hz	Low-pass cutoff for the feedback path.
Lo Cut	20..500 Hz	80 Hz	High-pass cutoff for the feedback path.
Ping Pong	Off, On	Off	Crossfeeds the repeats between channels instead of feeding each channel back into itself.
Div	1/1, 1/2, 1/4, 1/8, 1/8., 1/8T, 1/16, 1/16., 1/16T	1/4	Selects the synced delay division used when Clock is patched.

Timing Behavior#

• With no recent clock edges, the module uses the Time knob directly.
• When Clock is patched and a stable pulse train is present, the module measures the incoming period and derives the delay time from Div.
• If the clock stops for about two seconds, the module falls back to manual Time.
• Time CV applies exponential time scaling, so it behaves like a pitch-style multiplier rather than a simple offset.

Repeat Character#

• Hi Cut and Lo Cut act on the feedback loop, not just on the final output, so the repeats change character as they recirculate.
• Ping Pong makes left repeats feed the right side and right repeats feed the left side.
• High FB values move from clear echoes into longer ambient tails.
