Not rated yet
K7D is a tape-style delay from Imaginando that models warmth, wow, flutter and saturation that builds up with each repeat.
It adds feedback filters, ping-pong and width controls, MIDI key-follow for the delay time and feedback up to 200%, for €39 (about $44).
Best for: Guitars, Vocals, Keys & Synths, Sound Design. Genres: all genres.

What it does
K7D is Imaginando's tape delay. It aims to recreate "the warmth, motion and gentle degradation of real tape echo" through separate, adjustable stages, and adds modern modulation and MIDI tracking on top.
- Delay line: 1 to 1000 ms on an exponential curve for fine control at short times, free in milliseconds or synced to host tempo, with 4-point cubic interpolation for smooth pitch glides.
- Drive and saturation: a 0 to 20 dB pre-amp drive on the input, and in-loop saturation that re-saturates every repeat so echoes get warmer as they fade.
- Tape motion and noise: separate wow (about 0.48 Hz) and flutter (about 19.5 Hz) pitch modulation, plus noise injected into the feedback loop for hiss.
- Feedback and filters: feedback from 0 to 200% for self-oscillating drones, with 6 dB/oct low-pass and high-pass filters (25 Hz to 10 kHz) inside the loop so each repeat loses bandwidth.
- LFO: sine, square, saw, triangle, sample-and-hold and filtered S&H shapes from 0.01 to 10 Hz, free or synced, driving delay time and both filters with bipolar amounts.
- Keyboard Follow: the delay time tracks incoming MIDI notes, turning echoes into tuned comb-filter and resonator tones.
- Stereo: stereo spread, ping-pong and a 50 to 100% width control, with an option to invert the LFO between left and right.
It is sold outright or rent-to-own, with a 14-day refund guarantee; a bundle with DLYM and GRFX is also available. The demo never expires, but plays a noise burst every 60 seconds and disables saving until you buy a license.

When to use it
K7D is the better pick for a cheap, playable tape delay that rewards pushing the feedback. Unlike EchoBoy, it does not model a range of specific echo units, but at a fraction of the price it covers the warm, wobbly, degrading repeats most people want from tape. Compared with Galaxy Tape Echo and Arturia's Delay TAPE-201, which recreate the Roland Space Echo closely, K7D is less tied to one machine and adds Keyboard Follow and a multi-shape LFO. Its 200% feedback makes it easy to tip into self-oscillation for dub throws and drones.
- Best for: warm repeats on vocals, guitars, keys and synths, dub-style feedback swells, and tuned comb effects via MIDI.
- Genres: any; dub, lo-fi, ambient and electronic music get the most from the feedback and modulation.
- Look elsewhere if: you want many delay styles and rhythm patterns in one plugin (EchoBoy) or a faithful Space Echo model with spring reverb (Galaxy Tape Echo).
- Tip: push the pre-amp drive to add crunch to beats before the repeats even start.
What producers say
Early reviews were warm about the sound and the price; the main wish was for more control over tape condition.
- Audio News Room (2019) called it a "well-designed, easy to use, great sounding" delay, praising the minimal interface, the LFO on the filters and the presets.
- Criticisms: the same review missed a tape-age control to move between clean and worn tape, and found the iPhone interface small.
