MewDelay is a stereo delay whose echoes “evolve” the more they repeat. With each feedback pass, drive and bit crush can rough things up, pitch can drift, and the modulation and stereo image can deepen — the tail changes over time.

(Dry bypasses the loop and is mixed in)
ECHO EVOLUTION runs inside the feedback loop, so the effect accumulates with every repeat (the very first echo already has one pass applied). POST FX runs at the output stage and applies a constant amount per echo.
Ducking only acts on the delayed signal (Wet) — it does not attenuate what is inside the feedback loop (a classic behavior where the echoes return as soon as the input stops).
Time & Feedback — the delay foundation
| Parameter |
Description |
Sync |
Sync to host tempo. When on, the right Div selects the length. |
Div |
Note value when synced (1/1 through 1/32, including dotted and triplet). |
Reverse |
Plays echoes in reverse. Heads align on silent-to-sound transitions, so the same phrase always reverses the same way — it’s reproducible. |
Time |
Free delay time in ms when Sync is off. Moving it shifts pitch smoothly like tape, with no glitch. |
Spread |
Offsets the left / right delay times for a stereo feel. |
Fdbk |
Repeat amount. The sustain / decay is set by this knob (the internal level is matched so the loop does not blow up even with heavy drive). |
Tone |
Low-pass filter in the feedback path. Lower values darken the repeats — an analog / tape-style decay. |
| Parameter |
Description |
Input |
Input gain. Use it to drive the distortion stages harder. |
Dry |
Amount of dry (original) signal. |
Wet |
Amount of delayed signal. |
Out |
Final output level. |
| Parameter |
Description |
Duck |
Turn ducking on / off. While the input (or the sidechain) plays, the delayed signal is suppressed. |
Src |
Detection source. Self = the plug-in’s own input; Sidechain = the external sidechain input. |
Thr |
Threshold at which the suppression kicks in. |
Depth |
Depth of suppression. |
Atk |
How quickly the suppression engages. |
Rel |
How quickly the echoes come back. |
To use Sidechain, route a different track’s signal into MewDelay’s sidechain input from your DAW.
Motion — animate the echo’s position
| Parameter |
Description |
Pan |
Turn pan modulation on / off. Animates the stereo position of the echoes. |
Mode |
Ping-Pong = alternate left/right; Sweep = continuous sine motion; Random = a new position every time. |
Depth |
Pan motion amount. |
Rate |
Speed. ×1 is one cycle per delay; higher values are faster. |
Echo Evolution — stacks with every repeat (inside the feedback loop)
Each module can be switched on / off, and Amt (amount) sets the strength per pass. Because they sit inside the loop, the effect deepens as echoes pile up.
Drive — overdrive
| Parameter |
Description |
Amt |
Soft, warm saturation. 0 = off. Adds gentle upper harmonics that thicken with each repeat. |
Dist — distortion
| Parameter |
Description |
Amt |
Hard, edgy distortion. More aggressive than Drive — repeats grow grittier. |
Crush — bit crush
| Parameter |
Description |
Amt |
Lowers the quantization bit depth, roughening the sound. The texture coarsens with each repeat. |
Pitch — pitch shift
| Parameter |
Description |
Amt |
Shifts pitch up or down (tape-speed flavor). Positive raises, negative lowers. The shift accumulates with each repeat. |
Glide |
OFF = a stepped shift per echo. ON = the tail glides continuously once the input stops (Amt sets speed and direction). |
Post FX — constant amount per echo (output stage)
The spatial effects run at the output stage, so they stay stable and do not affect delay time.
Modulation — wobble
| Parameter |
Description |
Depth |
Modulation depth (chorus / vibrato style motion). |
Rate |
Modulation speed. |
Stereo — stereo widening
| Parameter |
Description |
Amt |
Widens the stereo image of the echoes. Even a mono input gains a natural width. |
Detune — detune
| Parameter |
Description |
Amt |
Slightly detunes left and right against each other to prevent cancellation against the dry signal. Bipolar (0 = off). |
Levels — meters
| Item |
Description |
IN / OUT |
The meter on the right shows input (IN) and output (OUT) peaks for each side. |
Usage tips
- For a clean delay, turn ECHO EVOLUTION and POST FX all off. With just
Fdbk and Tone, you get a straightforward tape / digital delay.
- For a growing tail, push
Fdbk higher (0.7+) and gradually bring in Dist, Crush, or negative Pitch. The repeats deteriorate over time.
- For a special effect, try
Reverse + Pitch (with Glide ON). The heads align on each phrase, so the result is reproducible.
- The plug-in passes signals above 0 dB through without clipping. Manage the final level with a limiter or similar afterwards.
