"What a stellar and musical delay. I put this up there with Kosmonaut on iPad. What a generous set of presets. It’s also so easy to use and create your own presets. This feels more creative than Valhalla DSP’s delay. Just…"

K7D.
A tape delay. Every echo,
a new generation.
A tape-style delay that recreates the warmth, motion and gentle degradation of real tape echo — with a deep modulation engine and creative controls that go well beyond a vintage emulation.
[ OVERVIEW ]
The short version.
K7D isn't a static digital delay with a "tape" preset — it models the physical behaviours that make tape echo musical, and rebuilds them as discrete, controllable stages.
Interpolated pitch glide, in-loop saturation, feedback-path filtering, wow & flutter and analog-style hiss — each one a real stage in the signal path, not a faked artefact.

01 · What it is
Tape soul, modern control.
Real tape warmth, wow & flutter and self-degrading repeats — but with smooth musical filters, tempo sync and a full modulation engine layered on top.
02 · What it does
Slap-back to self-oscillation.
1 ms to a full second of delay, feedback from 0 all the way to 200%, drive on the input and saturation inside the loop — controlled echoes or infinite swelling drones.
03 · Why it's different
A delay you can play.
Keyboard-follow makes the delay track incoming MIDI pitch, turning echoes into tuned, playable resonator and comb textures from your keyboard.
[ ENGINE ]
The behaviours that make tape musical.
01 · feature
Reels that glide, not steps that click
The delay line reads with 4-point cubic interpolation off a fractional read head, so moving the Time knob bends pitch like spooling tape — never the zipper-click of a stepped digital delay.
02 · feature
Every echo, a new generation
A saturator sits inside the feedback loop, so each repeat is re-saturated. Echoes compress and thicken the longer they sustain — warmer and more worn than the last.
03 · feature
Echoes that dissolve
A low-pass and a high-pass filter live in the feedback path. The tail loses highs and lows with every pass — gentle 6 dB/oct curves that narrow the bandwidth instead of piling up.
04 · feature
Wow & flutter
Two independent pitch LFOs model speed instability — a slow Wow and a fast Flutter. From a gentle sway to a seasick warble.
05 · feature
Hear the machine breathe
A noise source is injected into the feedback loop, so cranked feedback and self-oscillating washes pick up authentic analog-style hiss and grit.
06 · feature
One LFO, three destinations
Six waveforms — sine, square, saw, triangle, sample & hold and filtered S&H — drive Delay Time, Low-pass and High-pass, each with its own bipolar amount from −100% to +100%.
07 · feature
Stereo that moves
Stereo Spread offsets the right channel against the left, Ping-Pong bounces repeats across the field, a 50–100% width matrix sets the image, and inverting the LFO flips L/R for opposing modulation.

[ FAQ ]
Quick answers.
The questions we get asked most about K7D.
What is K7D?
+
K7D is a tape-style delay that recreates the warmth, wow, flutter and saturation of vintage tape echo, with modern modulation and tempo sync.
Which platforms and formats does K7D support?
+
K7D runs on macOS and Windows as a VST, VST3 and AU plugin, and on iOS as an AUv3 plugin and standalone app. The standalone app is iOS-only.
Can K7D sync to my project tempo?
+
Yes. K7D syncs delay time to your host tempo in musical divisions, or runs free in milliseconds.
Is the iOS version separate from the desktop plugin?
+
Yes — the desktop plugin and the iOS app are sold separately (the iOS app is on the App Store).
Can I try K7D before buying?
+
Yes. A free desktop demo lets you hear it in your DAW before buying. The demo is desktop-only.
