Crap Cassette by SESDevices: A C90 Deck in an Audio Rack

· max4.live editorial

Crap Cassette by SESDevices does one thing: it emulates a good old C90 tape playing back on a less than perfect deck. That is the whole pitch, and the author leans into it — the description talks about the golden age of the compact cassette, and about the pencil you needed when your deck turned an album into brown plastic spaghetti. Underneath the nostalgia is a working audio effect that, in SESDevices' own words, ranges from subtle to downright nasty.

It landed on 4 June 2015, at version 1.0, and has never been updated. It has 20,731 downloads, a 5/5 rating, and 14 comments. For a single-purpose colour box with no licence attached, those are strong numbers, and they're worth unpacking before you decide whether to install it.

No manual, by design

SESDevices explicitly declines to document the controls: "No explanation of the controls should be needed." That's a design statement as much as a shortcut. The device assumes you know roughly what a worn cassette sounds like and that you'll find the shape you want by turning things until it matches the memory in your head.

Practically, that means you should audition it the slow way. Load it on a single sound you know intimately — a drum loop you've heard a thousand times, or a vocal take — set everything to its minimum, and move one control at a time to its extreme before backing off. You'll map the device in about five minutes. Trying to dial a finished sound by moving three things at once on an undocumented effect is how you end up with a preset you can't reproduce.

Once you've learned it, save your own presets immediately. There's no version history to fall back on and no parameter list to read, so your saved .adv files are your documentation.

Three places it earns its slot in a session

1. The sampled-loop pass. If you build from loops — breaks, chopped guitar, a two-bar synth phrase you bounced yourself — Crap Cassette is a quick way to make disparate sources sound like they came off the same medium. Put it last in the chain on the loop track, after any EQ, and set it conservatively. The point here isn't the effect; it's the glue. Freeze and flatten once you're happy, so the tape colour is baked into the audio and you stop fiddling.

2. The return-track wreck. Set up a return with Crap Cassette pushed toward the nasty end of its range, then send small amounts from several tracks into it. You get a parallel layer of degraded signal that sits behind the clean mix. This works especially well on sustained material — pads, strings, vocal tails — where the degradation becomes a texture rather than an event. Automate the send rather than the device: it's easier to undo and easier to perform.

3. The transition effect in a live set. Map one of its controls to a knob on your controller, drop the device on the master or on a group, and ramp it up across the last bar before a drop or a scene change. Because the device can go from subtle to extreme, the same control can serve as both a mild colour at rest and a full breakdown when you push it. If you perform with Live, this is probably the most valuable use — it's one knob that does something nobody expects from a filter sweep. Worth a word of caution: test the extreme setting at gig volume on your own system first, since heavy degradation effects can change perceived loudness quickly.

Where it sits among comparable devices

Browse the Audio Effect category around this download range and you'll notice something: popularity clusters don't mean functional clusters. The devices sitting near Crap Cassette's 20k downloads do wildly different jobs.

What 20,731 downloads and 5/5 actually tell you

A perfect rating is always worth reading carefully. With 14 comments against 20,731 downloads, the feedback sample is small relative to the install base, and people who dislike a free single-purpose effect usually delete it rather than rate it. So read 5/5 as "nobody who bothered to rate it was disappointed," not as "this is the best tape emulation available."

The download figure is the more telling number. Twenty thousand downloads for a device with no listed updates, no licence, and a deliberately joke-adjacent name means it kept getting recommended for a decade. Devices that don't deliver don't accumulate that quietly.

The compatibility question

This is the real decision point. Crap Cassette is listed for Live 9.1.9 and Max 6.1.9, version 1.0, added in 2015 with no update since. Many Max 6-era devices open fine in current Live versions, but some don't, and there's no maintained release to fall back on. There's no licence stated either, which matters if you're planning to use it on commercial releases and want something explicit in writing.

If you're running a recent Live, the sensible approach is: download it, load it into a scratch set rather than a project you care about, and confirm it behaves before building anything around it. If it works, bounce your results to audio early — don't leave a 2015 device as a live dependency in a session you'll open in three years.

Who should skip it

Skip Crap Cassette if you need documented parameters you can automate precisely and recall across machines — the no-manual approach is charming but it makes collaboration and recall harder. Skip it if you're on a current Live and unwilling to troubleshoot an unmaintained Max 6 device; High School Crush covers adjacent territory on a modern build. Skip it if you need explicit licence terms for commercial work.

Download it if you want a dedicated tape-degradation box, you're comfortable learning a device by ear, and you have the kind of set where one knob that can go from gentle to ruinous is worth having mapped. For that job, after ten years and twenty thousand downloads, it's a safe pick. More single-purpose effects worth a look are collected in the best-of lists.
