I built 3 free browser-based music tools (step sequencer, music theory explorer, chord generator) — no signup, no install

Hey folks — I've spent the last while building a small suite of free web apps for musicians/producers, no login or install required:

  • meloodi — a browser step sequencer with MIDI export, multi-track support, tap tempo, and scale/mode-aware note placement so you can't easily play "wrong" notes.
  • Harmonix — an interactive music theory explorer: chords, scales, circle of fifths, and progressions, all clickable/audible.
  • NextChord — generates chord progressions based on mood (happy, sad, tense, epic, dreamy, dark), scale and key — rule-based, no AI — and shows them on a piano roll + staff notation.

All run entirely in your browser (Web Audio), nothing is uploaded anywhere. I built these mostly for my own workflow and figured others might find them useful too. Would genuinely appreciate feedback, bug reports, or feature ideas — this is a solo side project, still actively improving it.

I created a multitrack MIDI generator with export function

Hello people!

My updated and final free version of my MIDI generator for generating melodies in different scales.

You can change the melody in the sequencer by painting and dragging notes and even export to MIDI with up to 4 tracks.

In each track you have different options for short or longer notes etc.

Right-klick (or on mobile tap and hold) to change the velocity of each note.

At the bottom you can save loops or chain them.

I hope this can help if you are stuck with no musical idea. Please give me feedback on the form at the bottom of my page or here in reddit.

Have fun!
