Linked with STAB

sold separately. made to lock together.

STAB is its own plugin and its own purchase, and BASS never needs it. But own both, open them in the same session, and BASS finds STAB by itself and follows its key, scale and chord roots as they change. No MIDI routing, no sidechain, no menu. TAP, the percussion plugin, joins the same way: it fits its groove around STAB’s hits.

01
Open STAB on a track.
Pick a key and a style. Hit SLASH until the stab is right.
02
Open BASS on another.
The sword goes through the fish. That is BASS saying it has found STAB.

Press play.
Change the key or the scale on STAB. BASS follows inside the bar. Hit BITE for a new line in the same key.

The sign

A plain fish means BASS is on its own. A sword through the fish means it is linked to STAB. Close STAB and the fish swims on alone, in the key you last had.

The BITE button with the sword through the fish.

Low end

STAB leaves the room. BASS fills it.

Turn LOW CUT on and STAB has no sub. BASS lives in that window, one note at a time. Same keys, same scales, same style names, so the two interlock by construction.

★★★★★

"The interface looks great and is super intuitive, so you can start generating interesting MIDI patterns straight away without having to learn a complicated workflow."

Questions

Is BASS a bass plugin or a preset pack?
A bassline generator. BASS writes the bass sound and the line together, every time you press BITE: subs, rolling garage basslines, acid-leaning lines, dubby low end. Lock the sound you like and reroll the line, or the other way round.

Does BASS follow STAB automatically?
Yes. Open both in the same session and BASS finds STAB by itself and follows its key, scale and chord roots as they change. Nothing to route, nothing to set up.

Does BASS work in Ableton Live 11?
Yes. Live gained VST3 support in 10.1, so anything from 10.1 up loads BASS, Live 11 included. Tested in Live 12 on Mac and Windows.

Do Mac and Windows come in one purchase?
Yes. One download covers macOS (universal, notarised) and Windows, as VST3, AU and a standalone app.

Do I need an account or an internet connection?
No account. Your licence key arrives with the Gumroad receipt, the plugin checks it once online, and from then on it works offline.

Can I use the basslines in released tracks?
Yes. Everything BASS makes is yours, royalty-free, in any release.
