Bassline MIDI Pack: UK Garage, UK Drill, Amapiano, Reggaeton, Afro House, Baile Funk

A bassline MIDI pack usually arrives in one key. You open it, your song is in F minor, the file is in A minor, and you start dragging notes in the piano roll. Shift the whole line down four semitones and it works. Shift it up eight and the root lands an octave higher than a bass should sit. That is the job this pack takes off your desk.

The pack holds 216 .mid files: 18 basslines in six styles, each written out in all 12 minor keys. The six styles are UK garage, UK drill, amapiano, reggaeton, Afro house and baile funk. Each file is 2 bars, one track, 480 ticks per quarter note, with the tempo written into the file: 132 BPM for UK garage, 142 for drill, 113 for amapiano, 95 for reggaeton, 122 for Afro house and 130 for baile funk.

The register rule is the point. In every key the root note sits between E1 and Eb2. E minor starts on E1, the lowest root in the pack. Eb minor starts on Eb2, the highest. Every other key falls between. Across all 216 files the lowest note is E1 (MIDI 28) and the highest is A#3 (MIDI 58), measured by reading every file back.

Take one example. UK garage, the 2-step skip bassline, F minor, 132 BPM. The root is F1 (MIDI 29), the line runs from F1 to F2, and it has 12 notes over 2 bars. At 132 BPM those 2 bars last 3.64 seconds. Change the key to A minor and the root moves to A1 (MIDI 33). Change the tempo to 140 BPM and the same loop lasts 3.43 seconds.

The drill files work differently. The next note starts one 16th before the previous note ends. That overlap is what makes an 808 glide, but only on an instrument set to mono with glide, portamento or legato switched on. On a polyphonic patch you hear two notes at once. Drill 02 also uses the flat second, the half-step above the root that gives drill its tension.

Reggaeton follows the dembow: three, three, two in sixteenths, the same tresillo shape as the snare. One of the three reggaeton lines walks i, VI, III, VII across 2 bars, the progression a lot of perreo sits on. Amapiano lines are short, pitched hits meant for a log drum patch. The baile funk lines follow the tamborzao pattern.

Getting a file into your DAW takes three steps. Drag the .mid onto a MIDI or instrument track in Ableton Live, FL Studio, Logic Pro, Reaper, Cubase or Bitwig. Load an instrument on that track, such as an 808, a sub bass or a log drum; without one the track stays silent. Keep your project tempo, and say no if the DAW offers to import the tempo from the file.

MIDI is not sound. It is note data: pitch, start, length and velocity. The tone comes from your own instrument, so the same file sounds different in every DAW and in every patch. Menu names also differ between DAW versions and UI languages.

What is free. The web page shows all 18 basslines in your key and at your BPM, note by note, with the note name, the position in the bar, the length and the velocity. A play button sounds the 2 bars in the browser. The UK garage 2-step skip bassline downloads free as a .mid in any of the 12 keys and at your own tempo, and that download is byte-for-byte the same file as the one in the pack.

What the pack adds. The other 204 files, already written, named by style, number, pattern, key and BPM, so you browse them from the DAW sidebar without a web page open. The price is $28 once, no subscription. A rival bassline MIDI pack on this shelf sells at $28 (our shelf measurement, 2026-10-01).

If your song is in a major key, use the relative minor: C major takes the A minor file, G major takes the E minor file.
