Slimline Delay

Compact delay with manual time, feedback, mix and CV control for Eurorack in 2 HP

The Slimline Delay brings short repeats, added density and modulated time shifts directly into the patch. In Eurorack, a delay is not merely an effect placed at the end of the chain. It can sit before a filter, become part of a feedback network, create rhythmic edges or transform a simple signal into a moving texture.

The module focuses on the essential controls: delay time, feedback and mix. These parameters determine how far the echo is separated from the original, how strongly it is fed back into itself and how prominent the effect is in relation to the dry signal. The delay time can also be controlled by CV, making time itself a modulation destination.

Why use a delay in a patch?

Short delays often change a signal more subtly than expected. A single impulse gains space, a percussive sound acquires a second edge, and a sequence begins to push and pull. Feedback creates denser repeats, more metallic contours or small resonant spaces. When the delay time is modulated, pitch movement, bends and unstable transitions are added.

This flexibility is especially interesting in a modular system because the delay is not tied to a fixed position. It behaves differently before a filter than after a VCA. In a feedback path, it becomes part of a larger instrument. Alongside a sequencer, it can increase rhythmic density without requiring additional notes to be programmed.

Delay time, feedback and mix

The manual delay-time control establishes the basic behaviour. Shorter settings are suitable for thickening, slapback-style effects or rapid rhythmic reflections. Longer settings give the echo more independence and make individual repeats more clearly audible.

Feedback determines how long the signal continues to circulate. Low settings remain controlled and rhythmically clear. Higher settings bring the delay further into the foreground and can develop small events into longer textures. The mix control keeps the balance between the original and the effect directly playable without requiring an additional mixer.

CV-controlled time

CV control of the delay time is the point at which the module becomes truly modular. An LFO can create gentle fluctuations, a sequencer can make time values jump rhythmically, and an envelope can set the echo in motion. The result is not merely a series of repeats, but reshaped transitions: time is stretched, compressed and audibly modulated.

This makes the Slimline Delay particularly interesting for compact effects chains, experimental voices and performance patches in which an effect should not remain static.

More than an echo at the end of the chain

A delay is especially rewarding in Eurorack when it is not treated solely as the final effect. Placing it before a filter creates different movement than placing it after one. Before a waveshaper, an echo can feed additional material into the distortion. In a VCA path, the effect can be opened rhythmically so that only selected repeats remain audible.

Feedback also does not have to take place exclusively inside the module. A delay output can be routed through other modules and mixed back under external control. This creates textures that sit somewhere between echo, resonance and a moving layer of sound. The Slimline Delay provides a compact and directly accessible time-processing element for such patches.

The effect remains playable because time, feedback and mix are all immediately available. Small changes are often enough to shift a patch from spatial depth to rhythmic instability.

Short delay times in particular respond sensitively to such interventions. A slight offset can thicken a signal, push a rhythmic line forward or, together with feedback, introduce a new edge into the sound.

Typical applications

• create short echoes, slapback and rhythmic repeats
• modulate delay time with an LFO, sequencer or envelope
• use feedback for denser textures and unstable edges
• keep the effect level directly playable with the mix control
• use the delay before filters, VCAs or waveshapers as a sound-shaping element
