DigiTape, Recoil, and WACKELPUDDING: 3 Free Plugins Worth Grabbing This Week

DigiTape brings two dead tape machines back from the 2000s

Pulsar Audio released DigiTape on October 27, free, for PC and Mac in VST2, VST3, AU, and AAX. It bundles two early digital tape emulation algorithms from the 2000s, back when processing power was limited and tape plugins had to cut corners. Pulsar built DigiTape to reproduce that specific, slightly compromised character rather than compete with today's more accurate tape models, and the two algorithms sit side by side so you can switch between them on the same track.

The range runs from a light warming to outright grit, and Pulsar describes the CPU load as low, which matters if you are running six or eight instances across a session full of layered bass and drum busses. The one catch: it needs an iLok account to activate, even though the plugin itself costs nothing. If you already have an iLok login for something else, this is a two-minute download. If you do not, factor that extra step in before you commit a mix session to it.

For a bass bus, DigiTape is worth trying ahead of a heavier saturator. Run a sub-bass track through it, A/B the two algorithms, and listen for which one adds body without smearing the low end. The lo-fi character means it is doing more to the harmonics than the fundamental, so your sub should stay intact even on the grittier setting.

Recoil ducks without an account wall

afugazi's Recoil is a free sidechain ducking plugin, VST3 and AU on macOS, VST3 only on Windows, and it asks for nothing: no email, no account, no login screen before the download starts. That alone makes it worth keeping around as a backup when a client session arrives with a sidechain effect you do not own.

Recoil works the way sidechain compression has worked for twenty years: it listens to a trigger signal, usually your kick, and pulls the level of whatever is routed through it down in response. The dip starts once the kick has already begun, which is different from how Low End Candy's own Preduck behaves. Preduck looks ahead and starts dipping the bass before the kick lands, then returns to full volume exactly as the transient arrives, so there is no residual pump sitting on top of the strike. Recoil's approach is the one most producers already know, and it is the right tool when you want that classic pump, not the pre-emptive dip.

Worth trying both on the same bass track back to back. If the bass note starts right as the kick lands, Recoil's reactive dip will shave a few milliseconds off the front of the note. Preduck will not, because it has already finished ducking by the time the kick strikes. Neither is wrong, they just solve slightly different problems.

WACKELPUDDING turns a spring into a wobble bass LFO

Kreuzberg Audio's WACKELPUDDING is a free wobble filter for macOS, Windows, and Linux, in VST3, AU, CLAP, and standalone, and it is licensed free for commercial use, so you can put it on a release without a second thought. Instead of a standard LFO sweeping the filter cutoff, WACKELPUDDING models a physical spring: push it and it oscillates with the spring's own damping and overshoot rather than a clean sine or saw shape. It ships with four filter types and 18 presets, and it includes an export feature that renders a vertical MP4 clip of the waveform and filter movement, built for pairing with a phone-shot performance video.

If you read this week's piece on Native Instruments' Massive XL and its new Tape Wobble effect, this is the free, lower-stakes version of the same idea: a one-stop way to sketch a dubstep-style wobble without hand-automating a filter LFO. See how Massive XL's wobble tools compare if you want the fuller picture. WACKELPUDDING will not replace a dedicated wavetable synth, but for pulling a wobble pattern out of an existing bass sound in thirty seconds, the spring model gives it a looser, more human feel than a straight LFO would.

Low End Candy's own free lineup just grew to four

Preduck has been live for over two weeks now, and the version history tells its own story about what producers actually asked for. It shipped as v0.2.0 on October 14, a pre-transient ducker built around one job: dip the audio routed through it just before a snare or kick strike, then return to full level exactly as the strike lands. By October 22, v1.0.0 added a new window layout with a draggable dip control for Lead and Depth, plus two new presets. v1.1.0 landed the next day with the ability to save and delete your own presets and a five-step first-run tour for anyone opening it cold. v1.1.1 arrived the day after that with Logic Audio FX placement and a separate Preduck MIDI AU so Logic users can trigger the duck from a note instead of a sidechain input, plus a fix for spacebar transport control inside FL Studio. The latest, v1.1.2, resized the window to fit smaller screens and sharpened the MIDI-routing hints across Logic, Live, and FL Studio.

Ten days, five releases, each one answering a specific gap rather than piling on features nobody asked for. Preduck is free to download in exchange for an email address, no card and no license key required, and it runs as VST3 on Windows and Mac, AU on Mac. It joins Ratchet and The Clap as the fourth plugin Low End Candy gives away outright rather than gating behind a trial.

None of the three plugins in this roundup, or Preduck, need an introduction from a sales pitch. Each one does a narrow job well, and in a week where the bigger headlines went to a $99 synth relaunch, the free tier quietly kept pace.

Which one actually earns a spot in your session

If your sessions already lean on a sidechain duck for kick-and-bass separation, grab Recoil first since it costs nothing to try and needs no login. If you are chasing tape character on a bass bus without reaching for a heavier saturation plugin, DigiTape is worth the extra iLok step. And if a wobble bass idea is stuck in your head and you do not want to program an LFO from scratch, WACKELPUDDING will get you there faster than expected.

Preduck earns its own slot regardless of which of the three you pick, since the pre-transient approach solves a different problem than any sidechain ducker, free or paid. Put it on your bass bus alongside a kick trigger and compare it against whatever you are currently using to duck. The difference shows up most clearly on dense, four-on-the-floor patterns where a reactive duck barely has time to finish before the next strike arrives.

A practical way to test all of this in one session: load Recoil on a bass bus return, sidechain it from the kick, and bounce eight bars. Duplicate that return, swap Recoil for Preduck, sidechain it the same way, and bounce the same eight bars. Flip between the two bounces in your DAW's browser and listen specifically to the attack of each bass note relative to the kick. Most producers have never actually heard the difference between a reactive duck and a pre-transient one outside of a plugin demo video, and having both free options installed side by side makes the comparison take five minutes instead of an afternoon of reading specs.
