AI MIDI generator for FL Studio: chords, bass and melodies into the Piano Roll

Chords in. Now what?

You've got the loop in the Channel Rack. Eight bars, on repeat, for twenty minutes. The next part isn't coming.

That's the spot LOCKDIN is built for. Load it on a track, give it the loop, pick the part you're missing and lock in. The take lands on LOCKDIN's piano roll as MIDI, in your key and in the same pocket. Like it? Drag it into FL. Don't? Run it back.

It doesn't make the beat for you. It hands you ideas in MIDI. You still pick the sound, the take and the arrangement.

How it works in FL Studio

1. Load LOCKDIN as a VST3 plugin in FL Studio.
2. Give it your loop. Drop a .mid onto the Session, or export your pattern as MIDI and drop it in. No loop yet? Start straight from the key and scale.
3. Pick the part: Chords, Bass, Topline or Countermelody.
4. Set the feel with four knobs: Creativity (tight to loose), Density, Swing, Gate.
5. Lock in. The take shows up on the piano roll. You can preview it at your project tempo.
6. Run it back until one hits. Every take stays in Takes, so nothing gets lost.
7. Lock it into the Session. LOCKDIN moves to the next missing part and writes it on top of what you kept.
8. Drag into DAW. Pull the clip out of LOCKDIN into your FL project. It's a real .mid file: notes only, so FL's tempo and your sounds lead. From there, open it in the Piano Roll and edit like any other pattern.

We're still testing the cleanest way to send a live FL pattern into LOCKDIN (Capture). Testers get a step-by-step guide.

Why MIDI, not audio

• Your synths, your notes. Put the MIDI on Sytrus, Serum, Vital, a Kontakt piano, whatever you run. LOCKDIN never picks the sound.
• Every note editable. Move it, re-voice it, add ghost notes, quantize it, slide it. It's your Piano Roll.
• Nothing baked in. No watermark in a bounce. What you make with it is yours to finish.

Four parts that talk to each other

Most tools give you one line. LOCKDIN builds a Session: chords first, then a bass that moves with them and leaves room for your 808s and drums, then a topline, then a countermelody that answers it. Each part is written around what's already locked.

Made for whatever you make

Every kind of beatmaker, any style, any key. The model is LOCKDIN's own, trained on MIDI that musicians picked by hand, on grid. You pick the feel with the controls.
