How do I make a chiptune melody for free?

Veena is an AI DAW with a personal music producer built in. Describe the song you want and CoProducer builds it with you — beats, chords, melody, arrangement and mix — as real tracks you can edit, mix and export. Free, in your browser. Ask for a chiptune melody and CoProducer writes it on Snap Pluck, a square-wave pluck on Veena's own synth, with Square Bass underneath.

What makes a melody sound 8-bit?

Square waves, one note at a time per voice, chords faked with very fast arpeggios, vibrato on long notes, and everything dead on the grid. Old sound chips had only a few channels, so every part had to earn its voice. Veena's CoProducer writes the lead, the arpeggio and the bass as separate tracks, the way a chip kept them on separate channels.

Can I use my chiptune melody in my game?

Yes. Veena's terms say you own the Output you generate through your use of the Service, and exports carry no watermark. Export the theme as 24-bit WAV or 320 kbps MP3 for your engine, every track as a separate stem for adaptive layers, or MIDI for another tool, as often as you like.

Chiptune Melody: 5 Patterns in D Major, B Minor and E Minor

A chiptune melody is a bright, square-wave line that moves fast and stays catchy with very few voices: a hook built from chord tones, chords faked with lightning arpeggios, and vibrato on anything held. Here are five patterns, from an overworld theme to a boss riff, written note by note. Veena, a free AI DAW with a personal music producer built in, writes them on its own square-wave synth, and CoProducer keeps each part on its own track like a sound chip's channels.

Five chiptune melody patterns

1. The overworld hook · Snap Pluck · D major, 150 BPM

8ths        1    &    2    &    3    &    4    &
Bar 1 (D)   A4   D5   F#5  A5   F#5  E5   D5   E5
Bar 2 (Bm)  D5   —    B4   —    F#5  —    D5   —
Bar 3 (G)   D5   G5   B5   D6   B5   A5   G5   A5
Bar 4 (A)   A5   —    —    —    E5   —    C#5  —

Bar 1 climbs the D chord and turns around; bar 3 answers with the same shape over G, which is what makes it sound like a theme rather than a scale. Bars 2 and 4 slow to quarters and a half note so the ear can catch its breath. Every note on a beat is a chord tone; the in-between notes pass by in 8ths.

2. The frame arpeggio · Bright Pluck · 32nd notes

Chord	Cycle these three, in 32nds
D	D5, F#5, A5
Bm	B4, D5, F#5
G	G4, B4, D5
A	A4, C#5, E5

Old sound chips could not play chords, so composers cycled a chord's notes so fast that the ear heard one shimmering chord. At 150 BPM a 32nd lasts 50 ms, twenty notes a second. Set the piano roll's snap to 1/8 Beat and draw the three notes on repeat for the whole bar.

3. The dungeon theme · Square Bass, drawn an octave up · B minor, 120 BPM

Quarters     1      2      3      4
Bar 1 (Bm)   F#6    —      E6     D6
Bar 2 (G)    E6     —      —      —
Bar 3 (Em)   G6     —      F#6    E6
Bar 4 (F#)   A#5    —      —      —

A slow, falling line in B harmonic minor that ends on A#, the raised seventh, pulling back to B. Long notes like these need vibrato, and Square Bass has it: pick it for this clip from the Bass + 808s shelf, turn MOVEMENT up, and every held note wobbles the way chip composers bent theirs. It is a hollow square over a sine sub, and it sounds an octave below the drawn note, so draw F#6 to hear F#5. Turn BODY down to trim the sine and BRIGHTNESS up to open the top.

4. The boss riff · Snap Pluck · E minor, 160 BPM

16ths   1   e   &   a   2   e   &   a   3   e   &   a   4   e   &   a
Riff    E4  E5  E4  D5  E4  C5  E4  B4  E4  C5  E4  B4  E4  A4  E4  B4

A pedal-tone riff: every other 16th hammers the low E while the notes between walk down the scale. One voice sounds like two, and the speed does the menace. Snap Pluck is gone in about 70 ms, so even at 160 BPM the 16ths never smear.

5. The walking bass · Square Bass · under the hook

8ths        1    &    2    &    3    &    4    &
Bar 1 (D)   D3   F#3  A3   F#3  D3   F#3  A3   F#3
Bar 2 (Bm)  B2   D3   F#3  D3   B2   D3   F#3  D3
Bar 3 (G)   G2   B2   D3   B2   G2   B2   D3   B2
Bar 4 (A)   A2   C#3  E3   C#3  A2   C#3  E3   C#3

Root, third, fifth, third in 8ths: the bass outlines every chord on its own, so the arrangement sounds full with only three voices. Drawn in octave 2 and 3, it sounds an octave lower, right where an 8-bit bass sits.

Make it sound 8-bit in Veena

Snap Pluck is the lead. A square wave with a pitch blip on every attack. MOVEMENT sets that blip from none up to a full octave, the difference between a clean note and a video-game "bloop". It dies away by design, so for held notes like bar 4 of the hook, open the synth panel's Envelopes card and raise Amp Sustain.

Keep it on the grid and in mono. One note at a time per track, quantized hard, no swing.

Fake the echo. Copy the lead clip onto a second track, move it an 8th later and pull its velocities down by half. That's how 8-bit composers doubled a melody with a spare channel.

Drums from the sample search. Ask CoProducer for 8-bit drum one-shots; it shows 10 preview cards, and you load the ones you like onto the 16-pad sampler. Or keep the Electronic kit and let the melody carry the retro.

Make a 150 BPM chiptune overworld theme in D major over D, Bm, G and A, one chord per bar: a Snap Pluck lead that climbs A, D, F sharp, A in bar 1 and answers with the same shape over G in bar 3; a Bright Pluck chord arpeggio in 32nd notes cycling each chord's three notes; a Square Bass walking the chord tones in 8ths; tight drums on the Electronic kit with the snare on 2 and 4. 4-bar intro, 16-bar A section, 8-bar B section in B minor, then the A section again.

CoProducer writes first the parts others depend on, then the rest against the notes actually placed, with 3 options for each. Hum a theme instead, and it transcribes your voice to MIDI on a new track, ready for Snap Pluck. In Veena's own data, 86.2% of new users who ask for game music or chiptune get a finished first result on day one.
