Marlow is one person.

I'm Ken Berglund. I write and produce pop music in Gothenburg, mostly for Japan and Korea. Snow Man, Isak Danielson, and a run of artists across Europe and Asia. Somewhere past two and a half million records sold on physical formats, which is a strange sentence to be able to write in 2026, and one of the reasons I like working where I work.

I still make records. That is not background for this; it is the whole reason the plugins exist.

I have been building things for my own sessions for years. Most stayed there: too specific, too ugly, welded to one song and useless the moment it was finished. A few kept getting opened long after the record was delivered, and turned up in work they were never built for.

Those are the ones I am releasing. Tape Sway is not the first thing I made. It is the first one finished well enough to hand to somebody else.

I am putting them out because they might be useful to you as well. Nothing more is being claimed.

Most days I am not looking for a cleaner sound. I am looking for the thing that makes a take feel like it happened somewhere, to someone, on a particular afternoon. Those tools are rarely the ones with the most controls, and they are almost never the ones designed by measuring something.

So Marlow makes two kinds of thing, and I do not think they are as different as they look. Some are creative: they do one strange thing properly, and they change what you write rather than how it sounds at the end. Some are useful: they do a job a professional does forty times a day, and they get out of the way while doing it. Both are made by the person using them, rather than for the person using them.

The catalogue grows slowly. I would rather release one tool I stand behind than ten I tolerate. Fewer products, made with more attention, remembered longer. Each one is finished before it ships.

The writing matters as much as the code. So does the room, the record playing in it, and the reason you reached for the plugin in the first place. I assume you know what a transient is. I will tell you how I think a tool should be used, and then leave you to ignore me.

That is the whole pitch. The tools are on the desk. You are being let in.
